A special issue on volcanic centers as targets for mineral exploration

NEPTUNE or Pluto? Since the days of Hutton and Werner, every generation of economic geologists has addressed this question in a new light. Most papers in this special issue deal with the thin and leaky roof of Pluto's underworld. It allows hot emanations from Hades to leak out, only to be quenched and diluted by waters percolating down from...

Mineralogy, paragenesis, and mineral zoning of the Bulldog Mountain vein system, Creede District, Colorado

The Bulldog Mountain vein system, Creede district, Colorado, is one of four major epithermal vein systems from which the bulk of the district's historical Ag-Pb-Zn-Cu production has come. Ores deposited along the vein system were discovered in 1965 and were mined from 1969 to 1985.Six temporally gradational mineralization stages have been...

USGS analyst performs DNA extractions in a laboratory
December 13, 2012
A U.S. Geological Survey analyst performs DNA extractions on enriched cultures of water from the study area. Once the DNA was extracted it was used to detect pathogen gene markers using polymerase chain reaction (PCR). Scientists have found that the presence of indicator bacteria, hepatitis E virus (HEV), and numerous bacterial pathogen genes increased following precipitation-induced runoff...
Game camera image of an osprey taken on Poplar Island, Maryland
June 28, 2012
Game camera image of an osprey taken on Poplar Island, Maryland. Game cameras were used to identify species of fish fed to osprey nestlings. The image was taken during a U.S. Geological Survey (USGS) study on organic contaminant levels and the reproductive success of ospreys in Chesapeake Bay . Changes in the regulation and use of some organic chemicals have caused environmental concentrations to...
USGS scientist standing in a stream. The rocks in the stream have iron precipitates
