Structural Geology Course: Lecture 7 (Interpreting geological maps/Introduction to outcrop patterns)
Просмотров 2283 месяца назад
Outcrop patterns are the visible exposures of rock formations on the Earth's surface. They represent areas where the underlying geology is exposed due to erosion, weathering, or tectonic activity. These patterns are crucial for interpreting geological maps because they provide direct evidence of the rock types, structures, and stratigraphic sequences present in a particular area. By analyzing o...

Interesting info. Just learned that the 12 gem foundation in the Heavens are made with the antsotropic minerals so they can shine! The one we would think as more valuable to us is not one of them which is the diamond that is isotropic!

Thank you for a clear and concise explanation on a highly controversial subject
Much appreciated 🙏🏼
As an interested layperson, this helped me understand how geologic maps may not be used alone, but as context for other info or site studies. So thank you.

Making an offhand comment to my wife about how borax can be used in fire assay to an AI narrated video in 2 hours, thanks modern world, I hate it here
That’s true, let’s be thankful to the modern world. I appreciate your input as well.
I appreciate your taking the time to put this together, thank you.
Much appreciated 🙏🏼
this was really helpful
Much appreciated 🤗
Can nobody narrate these days, must we now be subject to endless half baked AI readings, with no recourse to correction? "Amethyst colour due to trace ammounts of fay in the crystal", if it were not for the provided script I would have been stuck wondering exactly what "fay" was. Fe, iron you banana brained nit wit who decided to delegate this reading to an AI engine instead of getting a huiman who knew what they were actually reading to do it.
exactly what I was looking for! However, not in-depth enough! References!! Where can I find more??
Thank you so much. For more information check Tulane University (www2.tulane.edu/~sanelson/eens211/mineral_chemistry.htm) and article by Charles. A Geiger (Solid solutions: Background, history and scientific perspective, 2001).

Well explained Mr Malebati Sir
Thank you so much 🙌
Cation ( Read as Cat - Ion) .. Anion ( An-ion).. Great video, overall though..
Thank you for your input🙏🏼
While the content itself was exactly what I was trying to understand, the super annoying piano music was so distracting I couldn't retain the information properly. In my opinion drop the music.
Point taken. There is a room for improvement. Thank you for sharing your thoughts🙏🏼

Too difficult to listen to.
Ask I’ll be happy to help
I remember learning of unconformities, and thinking how weird the word “unconformity” sounds. It seems to go against the rules of the English language.
😂it’s a weird name indeed. Geological terms seem to have nothing to do with English
Enjoy this episode💯💥❤
This is very helpful
Thank you. Much appreciated 🎉🙏🏼
I LOVE your Videos.
Thank you so so much. Much appreciated 🎉
Does a GeoPhysical Survey Chart or Map actually look like anything like that shown in the Video?
This is for demonstration purposes. But more or less the same. Wherein colors plays an important role during interpretation (e.g., red colors in magnetic methods may show the rock below the surface which are associated with high magnetic values, however, the opposite is true for blue colors). For more information I recommend you visit: Geophysics for the Mineral Exploration Geoscientist. By Michael Dentith and Stephen T. Mudge.

Hello guys enjoy this wonderful episode🥹🙌❤️. Sorry about some mini breaks (it was network issues) and at about 18:51 (sorry guys, i meant to say the Sand River Gneiss is like a base, the Beit Bridge Complex was deposited on top as a cover. Enjoy and stay tuned ✨❤️❤️❤️❤️❤️❤️
The red line means "magma composition"? What is exactly the red normaliced lime?
The red line represent the standard composition which serves as a frame of reference. This is either Mid-Oceanic Ridge Basalt or Chondrite which have known composition.Then any shift in composition from this line is an anomalous change (enrichment or depletion).
Amazing content to study
Geochemistry is magical 🙌
