A translational landslide is when rock or soil moves down-slope along a plane of weakness like a joint, fault or bedding surface. Best illustrated with chocolate and a weaker layer of caramel.

In this video, Phil recreates two stages of the geologic history of Triton Bay, West Papua (northwest New Guinea).

In this model Phil Prince takes us to the Ouachita Mountains of Arkansas and Oklahoma.

Atlin was chosen for our field site because it’s home to an ophiolite, a rare place on earth where the crust and mantle are exposed at the surface.

Yesterday we were investigating marine volcanism via underwater fumaroles, and today we’re exploring the terrestrial side of Dominica! Scott Brame, a professor at Clemson University, took us to some of the most interesting geological features this volcanic island has to offer.

In this first part of a four part series, Dr. Phil Prince explains why we get the valleys and ridges that are the namesake of the Valley and Ridge province of Virginia.

A tour of Appalachia, as reconstructed Virginia Tech Active Tectonics and Geomorphology Lab.

From Khulna in the SW, we are heading to Rajshahi on the Ganges River, but first we are stopping at Kushtia, Humayun’s home town. Because the road on the more direct route is supposed to have bad road conditions, we took a longer route, way longer.

This video shows the development of a restraining and a releasing bend and then shows a cross-section of the model highlighting the different flower structures…

A “forensic geology” perspective on Hudson River School painting and sense of place

New video of a laboratory model which reproduces the decollements — essentially horizontal faults — on which the 2015 Gorkha earthquake rupture occurred in Nepal.

Zhemchug Canyon is 20 percent longer and deeper than Grand Canyon and is a t-shaped cut in the sea floor beneath the gray waters of the Bering Sea. On a Greenpeace-sponsored expedition, Michelle Ridgway, a marine ecologist and consultant from Juneau, descended into the canyon alone in a tiny submarine.

In this video continental crust is first pulled apart during extension and then tectonic forces change direction and the crust is put under compression. What results is first a basin and then an inverted basin.

If this rock was metamorphosed 25 km deep, why am I holding it now? How did it get back up here? This is a reasonable question for students to ask, and requires them to consider the combined effects of rock uplift and erosional removal of overburden.

We call the Appalachian mountains home and understanding our local geology can be challenging to students. How do you explain the juxtaposition of different rock types within the orogen? What tectonic processes are responsible?
Sometimes, a great idea arrives ahead of its time. A person squints at a raw landscape, thinks about it in his bunk on a heaving ship, dreams of it. He scribbles a diagram. He remains quiet years later as others rediscover the same thing.

In this four part video series, The Geo Models takes you to see Seneca Rocks, WV – an almost vertical limb of a now breached anticline.

In this model we show how different subsequent types of faults form in relationship to a strike-slip fault like the San Andreas fault.
