This is “just” a view of Mount Fuji - the highest mountain in Japan, actually a stratovolcano

In geology, folds are formed when originally horizontal layers of sedimentary rocks are bent and/or curved as result of acting temperatures and pressures. This is an absolutely stunning example of fold formation – click the pic for full size.

Crocoite is a fairly rare mineral in many parts of the world, consisting of lead chromate, PbCrO4. The relative rareness comes from the way it forms: it requires an oxidation zone of lead ore bed and presence of what are called ultramafic rocks, which act as a source of chromium. Ultramafic rocks are 90% mafic minerals (dark colored, [...]

What you are looking at is an entirely natural landscape – it is a sandstone rock formation, formed when dinosaurs roamed the Earth, in the Jurassic. Dinosaurs went extinct and the U-shaped formation got eroded, and after their formation, the drainage basin, which fed rainwater to these troughs, shrank to the point that that the [...]

What you see here is calcite and hematite. Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3), while hematite is a mineral containing oxygen and iron (Fe2O3).

This truly wild picture shows the stunning beauty which can result when a volcanic eruption creates lightning. A detailed explanation about why this happens can be found here.

I recently received this picture in an email from one of you guys, and while I think this picture is just mind blowing, I didn’t receive any information about where this is located or how it was formed. If you have any tips you can drop, that would be really great! If not… just enjoy [...]

What you re looking at is Mount Fuji, the mountain of the Japanese fire deity, the tallest mountain in Japan. It is actually an active volcano, which erupted for the last time in the early 1700s. As always, click the pic for full size.

Ok, what could rails have to do with this? Quite simple: these rails were thrown in this position by the move of the Earth’s crust, in Christchurch, New Zealand. According to seismologists, in some areas, it moved about 30 cm in some areas.

What you are looking at is Annapurna – one of the deadliest mountains on the face of the Earth. As always, click the pic for full resolution Picture source
