Clarence King, Geologist
May 2004 by Edgar B. Heylmun, PhDClarence King was born in Rhode Island in 1842, the son of a businessman. His father died when he was 6, so he was raised by his mother. She wanted to have Clarence attend the very best schools, and even moved in order to have him in the best district. She gave him a magnifying glass on his 7th birthday, and this led to his discovery of fossil ferns in neighborhood rocks.

…there are loads of different copper minerals, but a large number of them form first in the ground as chalcopyrite and then through the effects of weathering are changed into other minerals like malachite, cuprite and chrysocolla.
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
