Bedrock geologic map of the southern part of the Diorite and Champion 7 1/2 minute quadrangles, Marquette County, Michigan Bedrock geologic map of the southern part of the Diorite and Champion 7 1/2 minute quadrangles, Marquette County, Michigan
This map illustrates the bedrock geology of part of the Marquette iron range in the Diorite and Champion 7 ½-minute quadrangles. The area includes part of the Marquette trough, a synclinorium containing rocks of the Marquette Range Supergroup (Precambrian X) and older Precambrian W basement gneiss. Among the Precambrian X rocks is the economically important banded iron-formation, and the...

Manganese: it turns iron into steel (and does so much more) Manganese: it turns iron into steel (and does so much more)
Manganese is a common ferrous metal with atomic weight of 25 and the chemical symbol Mn. It constitutes roughly 0.1 percent of the Earth’s crust, making it the 12th most abundant element. Its early uses were limited largely to pigments and oxidants in chemical processes and experiments, but the significance of manganese to human societies exploded with the development of modern...

Geochemical and mineralogical maps for soils of the conterminous United States Geochemical and mineralogical maps for soils of the conterminous United States
The U.S. Geological Survey began sampling in 2007 for a low-density (1 site per 1,600 square kilometers, 4,857 sites) geochemical and mineralogical survey of soils in the conterminous United States as part of the North American Soil Geochemical Landscapes Project. The sampling protocol for the national-scale survey included, at each site, a sample from a depth of 0 to 5 centimeters, a...

Mercury in the soil of two contrasting watersheds in the eastern United States Mercury in the soil of two contrasting watersheds in the eastern United States
Soil represents the largest store of mercury (Hg) in terrestrial ecosystems, and further study of the factors associated with soil Hg storage is needed to address concerns about the magnitude and persistence of global environmental Hg bioaccumulation. To address this need, we compared total Hg and methyl Hg concentrations and stores in the soil of different landscapes in two watersheds...

History and progress of the North American Soil Geochemical Landscapes Project, 2001-2010 History and progress of the North American Soil Geochemical Landscapes Project, 2001-2010
In 2007, the U.S. Geological Survey, the Geological Survey of Canada, and the Mexican Geological Survey initiated a low-density (1 site per 1600 km2, 13323 sites) geochemical and mineralogical survey of North American soils (North American Soil Geochemical Landscapes Project). Sampling and analytical protocols were developed at a series of workshops in 20032004 and pilot studies were...

A national-scale geochemical and mineralogical survey of soils of the conterminous United States A national-scale geochemical and mineralogical survey of soils of the conterminous United States
In 2007, the US Geological Survey initiated a low-density (1 site per 1600 km2, c. 4800 sites) geochemical and mineralogical survey of soils of the conterminous USA. The ideal sampling protocol at each site includes a sample from 0–5 cm depth, a composite of the soil A horizon, and a sample from the soil C horizon. The
