2021-3-14 Most of the minerals that make up the rocks in the crust and mantle formed through the cooling of molten rock, known as magma. At the high temperatures that exist deep within Earth, some geological materials are liquid. As magma rises up through the crust, either by volcanic eruption or by more gradual processes, it cools and minerals crystallize.

2021-5-8 Diamonds are crystalline carbon and the hardest known substance. This photo shows diamonds from the Argyle Mine in northern Western Australia. Diamonds are brought to the surface from the mantle in a rare type of magma called kimberlite and erupted at a rare type of volcanic vent called a diatreme or pipe. Kimberlite is a gas-rich, potassic ultramafic igneous rock that contains the minerals ...

The seemingly barren moon may actually be a treasure-trove of priceless resources: a potentially bountiful, mineral-rich – yet untapped – cosmic quarry. Still, few see the moon as an alluring mining site, ripe for the picking of rare elements of strategic and national security importance. Here on Earth, China recently blocked the export of rare earth elements to Japan for use in an array ...
