The Wilson Cycle - Episode 4 - Collision and Collapse
The final of four episodes of "The Wilson Cycle" series. This is Episode 4: Mountain-building by continent-continent collision.
In this episode, we visit several localities with spectacular eclogites in Western Norway. These provide the evidence for the former deep burial and formation of a very thick, Himalayan type continental crust during the Caledonian continental collision between Baltica and Laurentia. The association of exposed mantle-rocks and the eclogite facies minerals formed at high- and ultra-high pressure conditions at 405 to 395 million years ago during the burial under the Caledonian Mountains in Scandinavia, provide solid evidence for the former presence of very thick oro...

The Wilson Cycle - Episode 3 - Ocean's Closing
Просмотров 3,9 тыс.2 года назад
The third of four episodes of "The Wilson Cycle" series. This is Episode 3: Closure of Major Oceans by Subduction. In this episode, we look at computer simulation of oceanic closure, island-arc and back-arc-basin formation by subduction and at the field-evidence for the initial intra-oceanic subduction-related formation of island-arc magmatism. We visit a large granodiorite formed by partial me...
The Wilson Cycle - Episode 2 - Ocean Opening
Просмотров 5 тыс.2 года назад
The second of four episodes of "The Wilson Cycle" series. This is Episode 2: Opening of large oceans by sea-floor spreading. In this episode, we have traversed west across the Caledonides in South Norway to look at the evidence for the former presence of oceanic crust that once was formed by sea-floor spreading within the Iapetus Ocean, which separated the two palaeo-continents Baltica and Laur...
The Wilson Cycle - Episode 1 - Rifting
Просмотров 10 тыс.2 года назад
The first of four episodes of "The Wilson Cycle" series. This is Episode 1: Rifting and Break-up of Continents. In this episode, we look at some of the geological evidence for the rifting and breaking-up of the Late-Proterozoic supercontinent known as Rodinia. This continental break-up resulted in the formation of the palaeo-continents Baltica and Laurentia. The continued rifting formed wide, a...
Earth's heat loss over time
Просмотров 2513 года назад
A new paper uses paleo-seafloor age grids and plate tectonic reconstructions to estimate variations in mantle heat loss since the mid-Paleozoic (400 Million years ago). Their results show that the Pacific mantle domain has lost heat at a much higher rate than its African counterpart since before the supercontinent Pangea (~ 370 Ma). Accounting for mantle heat sources, they inferred individual t...
LUSILAB - drone footage of the Lusi volcanic system in Indonesia
Просмотров 2923 года назад
Video by Adriano Mazzini (CEED, Uni. of Oslo/LUSILAB project). Lusi is the nickname of a volcanic/gas system that erupts water, oil, gas and mud and is located on the island of Java in Indonesia. It started to erupt in 2006 and, since then, has flow rate peaks of 180,000 m3/day (equivalent flow rate of around 8000 bathroom taps). The huge mud pool covering forced ~ 60,000 local residents to rel...

CLIPT Episode 5: Sediment and Soil Encapsulation
Просмотров 1,1 тыс.4 года назад
If you want to perform stable isotope analysis on materials with low amounts of organic material, you will need to load much larger amounts of bulk material into a tin capsule. In this video, I show you my technique on how to do this without the capsule bursting.

Here, I guide you through the process of preparing solid organic carbon and nitrogen samples for stable isotope analysis using an elemental analyzer configured with our mass spectrometer.
CLIPT Episode 3: How a Stable Isotope Ratio Mass Spectrometer works
Просмотров 12 тыс.4 года назад
Here we describe the basic operating principle of the mass spectrometer we use in the CLIPT Lab: a gas source, electron impact, magnetic sector stable isotope ratio mass spectrometer. For a more detailed description of how a mass spectrometer works, check out "Principles of Stable Isotope Geochemistry" by Zachary Sharp. This is a free resource that can be downloaded from : digitalrepository.unm...
CLIPT Episode 2: How an Elemental Analyzer works
Просмотров 17 тыс.4 года назад
This video walks you through the analytical cycle for the Elemental Analyzer the workhorse of our lab. It explains how we quantitatively combust bulk organic samples, purify and separate the carbon dioxide and nitrogen gases, and send them to the stable isotope ratio mass spectrometer for stable isotope analysis.

The interaction of mantle plumes and the Earth's surface
Просмотров 6 тыс.4 года назад
New study by Arnould et al. (2020) looked at how mantle plumes interact with both the mantle flow and tectonic plates, using global numerical models self-generating plate-like behaviour. They also focused on the mobility/stability of mantle plumes and studied the physical mechanisms leading to their stability/mobility. The movie shows the temporal evolution of surface topography (left panel) an...

    From Jake hossack (retired geologist). Great to revisit my early life as an academic geologist who mapped in Norway 1962 - 1977 and see outcrops that were discovered after I left. Also lovely to see again torgeir whom I met on a field trip in western Norway in late 1980 ‘ s. I was one of the early people to describe the Devonian extensional collapse of the Caledonian’s. Now at 84 am no longer able to see rock outcrops but enjoy watching others do it for me. Wish I had watched the series sooner. Jake

    Thank you for sharing the link. I found it really useful cause to me it wasn't clear the relations between measured and desired isotopic ratios. For example, how does the IRMS software derive the isotope relations from delta 45, 46, 47... given there are 9 isotopologues.
