geological and prospecting of gold

Gold - USGS

Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is con-centrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits. Lode deposits are the targets for the ...

Division of Geology and Mineral Resources - Gold

In Virginia, gold was mined from near-surface lode deposits, veins, mineralized zones, and placer deposits. Most of Virginia’s gold mining was in the “gold-pyrite belt”, a nine-mile to sixteen-mile-wide, nearly 140 mile-long northeast trending volcanic-plutonic belt that extends from Fairfax County to southwestern Buckingham County.

The gold deposits could then be worked year-round. In 1855, hydraulic mining began. The hydraulic mining was directed mainly at the gold-bearing Eocene river gravels on Spanish Hill, Texas Hill, and at Coon Hollow. Most of the drift and hydraulic mining occurred from the mid-1850’s to the 1870’s. Hydraulic mining stopped abruptly in 1884 with
