Here's another one for the structural geology fans out there. This is a photo of a cute little 'Z' fold in some Cretaceous strata in Patagonia (from this place). Sedimentologists and stratigraphers ...

An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide ...

As a geologist prowling the landscape along the coast for the past 40 years, I’m often stopped by folks asking what I’m doing. At the time I might be chipping away with my rock hammer, measuring the ...

Iran's folded rocks are rugged mountain ridges and valleys to the southwest of the Caspian Sea. They are an extension of the Greater Caucasus mountain belt, which also stretches along Russia's border ...

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name ...

A simulated view from above Tellus Tessera, one of the regions on Venus where Byrne et al. identify the presence of layering. Image generated from NASA's Magellan mission data. NORTH CAROLINA STATE ...

"Aside from volcanic activity, the other way to make layered rock is through sedimentary deposits, like sandstone or limestone. There isn't a single place today on Venus where these kinds of rocks ...
