Scientists report on the analysis of a surprisingly Earth-like Martian rock, discovered by the Mars Science Laboratory rover Curiosity, that offers new insight into the history of Mars's interior and ...

There are three types of rock found on Earth. These are igneous, metamorphic and sedimentary. Each rock type is formed in a different way. For example, the rock malachite is mostly made of the ...

UNIFORM with the “Rock Minerals” of the same author, now in its second edition, the work which Prof. Iddings has now completed will take an assured place as the fullest and most comprehensive ...

Scientists on NASA's Perseverance mission made a surprising discovery about the composition of rock in Jezero Crater, one that will help them get a better idea of when water existed on Mars, and ...

The first martian rock NASA’s Curiosity rover has reached out to touch presents a more varied composition than expected from previous missions. The rock also resembles some unusual rocks from Earth’s ...

One main goal of NASA's Mars 2020 mission is to determine when conditions on the planet were conducive to the formation of liquid water. Hence the target Jezero crater, seemingly a lakebed with a ...

I’ve been thinking about granite a lot recently; primarily because we have been covering plate tectonics in my AP Environmental Science class. Granite figures prominently in this discussion because ...

Subduction is a geological phenomenon that quite literally shapes the planet over time. Taking place at convergent plate boundaries, it involves the sinking of one tectonic plate underneath another ...

During the nearly 14 months that it has spent on the red planet, Curiosity, the Mars Science Laboratory (MSL) rover, has scooped soil, drilled rocks, and analyzed samples by exposing them to laser ...
