Central Washington University's Dr. Hannah Shamloo features the lab work of her graduate student Hailey Finch. Zircon separation details in the lab.
The relationship between the professors and students at CWU Geology is phenomenal. Your students love you, and it's obvious why. This is the absolutely best environment to learn in. Thank you for sharing your school, Nick and Hannah. Y'all are the best!
This is very illuminating. Seeing what's involved separating out the zircons helps in the never ending learning process.
Hearing the word zircon so many times in the various A to Z programs and watching this show is a wake up to how much I have yet to learn.
Funny how some particular shows really spark me. Thanks for this educational journey.
Loving this hands-on part of the process. Thanks for allowing us into the lab!
Hannah Shamloo is awesome as is Hailey Finch. Two fantastic women in science.
Wow - so cool to see how this process is done by the geologists, and Hailey did an excellent job explaining everything. Well done Hannah and Hailey, and thank you Nick for sharing this with us. CWU ROCKS!!
This was wonderful and so helpful to start to understand the mechanics of how the zircons are collected. Thank you!!
This was awesome. The process to extract zircons has been an ongoing question. Thank you Finch, Hannah, and Nick
Ms. Finch is very well-spoken and knowledgeable. Very impressed and hope to hear more from her!
Thank you for your superior channel!
Best wishes from a retired Geochemist.

Thank You, Nick Zentner, Hannah Shamloo, & Hailey Finch,
Who would have thought getting a Date from a Rock involved so much Work.
Great to see the process that actually separates the Zircon, the mineral that we have all heard about for so many years. Also the way the so called "waste" from this process actually is not waste at all, its another resource for another type of research. Pictures paint thousands of words. Thanks for that one Mr Zinger 😁
Nick, great, super fabulous story! Very very informative Thanks ❤❤
Very good video. It's great to see a grad student doing serious research with cutting edge tools.
Awesome, thanks for the Lab Lesson, Finch...you Rock! Slaying those Zircon samples!
I’m so impressed with this process, including the mentoring process. It’s good to see how student and teacher work together and the shared respect.
I LOVE YOUR CW LAB. LESS THE MACHINERY I WAS INVOLVED, MANY YEARS AGO, WITH THE SCIENCE LAB CONSTRUCTION AT UW. SUCH MEMORIES WORKING ALONG SIDE SUCH TERRIFIC AND TALENTED PROFS. I LEARNED SO MUCH!!
Thanks for the wonderful lab tour and demonstration. Hannah, Hailey, and Nick.
Thank you for the closer look at separating zircons from rock samples. Thanks to Finch, Hannah, and Nick for wonderful video!
Nick; Thank you and Hannah for sharing this process. I look forward to seeing more of the student help Hannah with her work. Hailey, outstanding clarity in your explanation. I hope you do the follow up for the next step. Hailey is easy to understand and clear on her description of processes. Great job. I am a lab tech and use similar processes in the paper industry.
Long time viewer, first time commenter. Outstanding video. Hannah and Finch are rockstars. You said it, Finch is a natural. Hopefully we'll see her more in the future. Nice job Ned bringing us into the lab.
Hailey Finch seems very knowledgeable, what a cool cat
I obviously chose the wrong major in college! I am so jealous! Great work Finch! And thanks for sharing Hannah, a new insight into the "How." Nick, more of these please.
This was a wonderful walk through of the process of collecting zircon. Hailey Finch is a rock star. Hannah is too. This brings the Goat Ricks researchers alive. Good idea!
Wow! Lucky us! To be able to get a glimpse of science in progress. So interesting to see this. Way to go people. We are a captive audience. Thanks CWU.
Those new microphones are a big improvement.
Saw this last night just before sleep. Put this on my calendar for this morning. I am very impressed with what this video shows. What is below the microscopic level, atomic? And then what?
CWU has its "stuff" together! Bravo with congratulations. 5 Stars.
What a fabulous program - hooray for CWU! 🎉
Thank you for this video. I wondered about this process because it's so important. It nice to see the lab side of geology. How I envy these students!! If only I were 55Yrs younger....
Great explanation. Would love to know how they prevent cross contamination in the rock crusher. Loved seeing the process. Thanks Hailey, Hannah and Nick!
Thanks again Nick, Hannah, Hailey and CWU for these videos!
I’m 71, but wish I was 17 again and would come to CWU and study rocks. Love the lab tour
Thanks for sharing the process to retain zircons from a rock sample. Great job CWU to build new machines to get it done.
Thank you to all.
I can't resist.......Oh, Hannah by gosh! Ohanapecosh was said so many times my mind just ran with it. Through out Nick's series I've been impressed with all the geologists knowledge and Hailey follows right along that vein with her ability to speak with confidence about her subject. Well Done! What wavelength of UV do you use? Will you be able to laser the zircons to read formation times?
Short wave (UVC) LED UV flashlights sit around 254nm. In the last few years, they have become reasonably priced and more available than the filtered UV lights of the past. Not cheap, but under $100.00
@@mr.morelock Thanks, I have a 395 and a 365 wavelength flashlights, Under $30 for both. Well made and effective. Great for looking at my rocks!
Thank you everyone. Dr. Lydia got zircons from my property, but I never knew what it took to seperate and prepare them.
Great tour, not like the labs I remember (1970's). Yep, mostly in the basements of old buildings, noise galore. I also remember doing mineral separations with with "heavy liquids". This when I questioned whether anyone in the field of Geology ever talked to anyone in general chemistry regarding using vacuum to speed up the separation process, used to take hours if not days to wait for the liquids to seep through the filter paper and then days to air dry. Think this is why I "click", with your approach. Keep up the great work.
Very nice! Thanks Finch, Hannah, and Nick.
Crushing it with the interviews!
Fabulous explanation. Hannah is such a good mentor teacher for Hayley.
I love it, so cool to see how they process the samples, this answers a lot of questions for me. Thanks to everyone.
Interesting to see how the lab process works. Thanks to both Hannah and Finch.
Thank you, what a pleasure.
Thank You. Donna Chassie
Awesome to see the laboratory also, great work 🎉
I wish I could go back in time and go back to school. What a great learning environment at CWU
Woo, my favorite people is showing us how they extract zircons from a rock!!💞💗✨Thank you Finch for being a good sport on the camera!! Go have geological fun at CWU!!😃
Thank you, Hannah, Finch and Nick. Interesting stuff!
That was great. We have such a great future with folks like this. It's inspiring.
Welcome to the next PBS series - Finch on the Rocks!
Thanks for the demonstration of the process of extracting zircons from the parent rock. With so many mentions of their value in dating I’m sure I’m not the only one left wondering about the reality of their extraction. I spent a few decades doing electron microscopy and X-ray microanalysis in the service of semiconductor technology development, but at conferences would drop in on the biology and geology sessions and be envious of the rich diversity of the samples nature created for their study.
most excellent. thanks for describing the process. we always wondered
Thank you !
Seeing this is awesome. Y'all rock!
Panning for Zircons..cool🎉
L enjoyed the 'how too process. Thank you Hannah & Halley
Loved it! That was very interesting. I like to see the process of turning a rock into zircons that can be dated.
Well, that's what it takes to get Zircon samples. Thanks for the training.
Zircons are so cool. One of the few lifeline tools available for understanding how old earth things are in billions of years.
Another great production! So good. Wife prefers diamond though. Keep up the great work.
So cool to see some of the lab side of geology.
What a job. But the end part looks FUN!
Interesting and great to see lab work! What is the specific gravity of Zircons? Gold being 19.3 do Zircons ever erode out in streams and concentrate naturally to any measurable amounts? Thank you Nick for a peek into lab processes!!
Zircon typically runs at about 4.6 -4.7 , so slightly denser / heavier than gemstones like corundum , garnet , and , diamond , spinel , etc .
They are found regularly in a lot of gem places with other stones , and , are a semi precious gemstone when of sufficient size , transparency , and , if reasonably free of fractures and inclusions .
@kaboom4679 thanks for info I thought garnets were around 9 but 4.6 vrs 2.8 for quartz isn't much difference
Excellent sharing of the method for separating and concentration of zircon crystals from host rock. Is it primarily felsic geochemistry, that favor the crystallization of zircon but not magic magmas?
Nice to see field samples processed to zircons with CWU inventions. Hayley did great.
That was fantastic 👏
Chris Mattinson following in his father's footsteps doing zircon work.
Central is an amazing geology school.
Hahaha definitely brought back memories of working in the diamond assay lab! I know how tedious it can be to get a sample down to that size, and also used to use methylene iodide for liquid sep. We also used a couple other methods of heavy liquids. LST is okay because it's non-toxic, but is very very sensitive to water bringing the density down (it's like nougat, a particularly humid day can ruin a batch of samples). We also used Fesi (Iron silicate, hence Fe Si) in a vortex to create artificial density in our big DMS plant. I specialized in micro-diamond recovery by caustic dissolution. I wonder if that could be useful in zircon recovery?
What is the process/equipment used to crush the rock? The separating process reminded me also of the gold table in the tv series "Gold Rush". Great video.
Nice to see how the field samples are processed. The “invisible” parts of the sample potentially have the most story to tell about the maturation of the magma prior to eruption. Thanks for the “behind the scenes” look in the lab!
I remember, zircons are very resistent, they can be subducted and come out again from a volcano hundreds of miles off. The zircons sometimes produced from Kilauea , the referent said, are suspected to be subducted on a plate border in the South.
Fantastic!
Hello Nick.... I so much enjoyed this video. A few years ago, I head about geologists looking for Zircon in rocks in Australia. Zircon was suppose to help in learning about when and how the magnetic poles of the earth moved/reversed? Am I confused?? I would be thrilled if you made a video on this as I have no understanding of it. Many thinks...
looks a lot like gold cleaning only way more technical. But to geologist it is gold. thank you, all good job.
It's a miller table , essentially .
Love this.
With zircons are they dating when those froze as opposed to samples that cool later such as potassium felspars and biotite which has a lower freezing point? I know you are probably using different dating methods for the minerals, but i was wondering if one can
I love to see the small details.
So cool!
This is nearly like fine gold recovery. Though zircon density isn't as high. (19.3 vs 4.6 g/cm^3) The rocks must get ground into a powder?
I was just catching up about Santorini. But good evening
On the job training. Fascinating!
5x5 yellows.
When I was in school, I wondered what the geologists were doing with a Wilfrey table ... and why did I, as a mineral processing engineer MS, not have a shake table in my basement lab. I was at UNR studying gold and figured the geos were too.
I now know why!
Reminds me of a fine gold recovery process. Very similar equipped.
Wondering how much of the magnetic material in sample is coming from the grinder?
Some for sure! We try to remove that from the sample before the water concentrator steps. We have some high powered magnets, it’s part of the early procedure Dr. Mattinson wrote up that I didn’t take time to go over :)
So Nick is inching closer to 100K mark where RUclips is gonna gift a plaque to Nick. I hope You get it by this month. BTW, Can I borrow the shaker table to pan some fine gold?
Reminds me of when I worked at the Oregon State University soil science lab as a student in 1989 grinding samples. Real science is tedious.
I remember mikroskoping heavy mineral sand. The zircons looked so very old.
Do zircons floresce in the uncrushed rock enough to be seen in the field?
Given the amount of zircon in these samples? Absolutely not.
Remember 1 kg of rock producing that tiny amount of zircon by mass. We're talking 0.1% zircon by mass at maximum. Chances of a crystal of zircon being at the surface of the uncrushed rock are tiny. Beyond that remember that they had to turn the lights off to properly see the fluorescence. You can't turn the sun off outside!
@davidpnewton was thinking of in a black box system and perhaps with a larger special flashlight and perhaps a detector more sensitive than the human eye for the frequency of emitted light... I admit the chance might be slim... but if it could detect surface zircons might it be a helpful tool?
do you guys have a IRMS or MCICPMS to do the dating in house or does it get sent out?
BTW, the world needs more woman scientists, now more then ever. Great work Hailey & Hannah!
Very similar to how gold is separated from concentrate on a gold table.
What a lovely atmosphere to get an education, as well as work in. Im guessing the pressures normal jobs have are far less in geology. The sample has waited 10 million years, I'm sure another day or two won't hurt anyone. lol
The flow meters are called rotometers or variable volumes flow meters invented by Fischer and Porter in the 1930’s
I saw “Goat Rocks Zircons” and thought of Cuzco the llama flashing bling on a catwalk…!
Just on toxicity safety grounds alone that Mattinson separation method is vastly superior to using heavy liquids that are nasty organic solvents.
Methyliodide looks fairly unpleasant based on its safety data sheet. The LD50 is 76 mg kg-1 orally whereas the LD50 for benzene is
930 mg kg-1 orally! Benzene has other hazards beyond its acute toxicity but I know it's been banned from use in undergraduate chemistry labs because it's so dangerous.
Beyond that drying something that's just wet with water is a heck of a lot simpler than getting rid of organic liquids. No explosion or fire risk with water for example.
