THE main object of the research described in this monograph was to ascertain the amounts of many of the less common elements, including, certain members of the rare earth series, in the minerals and ...

By comparing the amount of lithium and potassium with the other elements they detected - sodium and calcium - they found that the ratio of elements matched the chemical composition of the crust of ...

NASA has been exploring Mars since the 1960’s, but it wasn’t until today’s modern technology and advanced computers that they’ve been able to answer so many unanswered questions about the red planet.

Researchers have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition. Since early 2019, researchers have ...

Map of the thickness of the Moon's crust from GRAIL mission gravity data. Mean thickness is estimated to be 34-43 km. Imagine a system of molten silicate material, where low-density minerals float and ...

For decades, geologists have known that a huge portion of Earth’s earliest continental crust simply vanished from the rock record, as if someone had torn out the opening chapters of the planet’s ...

Geochemists have investigated the volcanic rocks that build up the Portuguese island group of the Azores in order to gather new information about the compositional evolution of the Earth's interior.
