Carbonates are sedimentary rocks formed by layers of carbonate sediment laid down by marine organisms such as corals. More than 60 per cent of the world’s oil and 40 per cent of the world’s gas ...

The study shows that the petrographic, geochemical and spectroscopic features in the graphite (the crystalline form of carbon) found in the Saglek-Hebron chemical sedimentary rocks are in fact ...

In 2004, the Mars Exploration Rover Opportunity spotted similar strange spheres, so-called "Martian Blueberries", and since ...
