In general, mineral particles are small, having formed within confined areas such as lava flows or between grains of sediments. Large crystals found in geodes and other rocks are relatively rare.

Petrology is the study of rocks - igneous, metamorphic, and sedimentary - and the processes that form and transform them. Mineralogy is the study of the chemistry, crystal structure and physical ...

Some minerals in rocks and organic matter (e.g., wood, bones, and shells) can contain radioactive isotopes. The abundances of parent and daughter isotopes in a sample can be measured and used to ...

SYDNEY, April 18 (Xinhua) -- Scientists' discovery of strong evidence of ancient, water-rich environments beneath Mars' surface offers new hope in the search for past life on the Red Planet.

“Our team found a way to measure the internal crystal structure of these minerals directly in the rock, which had thought to be impossible on the surface of Mars.” Jones is a co-author of the ...
