Mineral Diversity Clue to Early Earth Chemistry
February 28, 2013
Mineral evolution is a new way to look at our planet's history. It is the study of the increasing diversity and characteristics of the Earth's near-surface minerals, from the dozen that arrived on interstellar dust particles when the solar system was formed to the more than 4,700 types existing today. New research on a mineral called molybdenite provides important new insight about the changing chemistry of our planet as a result of geological and biological processes.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
