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...

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

Midcontinent microcosm: Geology of the Atkins lake - Marengo falls area (Field trip 2) Midcontinent microcosm: Geology of the Atkins lake - Marengo falls area (Field trip 2)
Archean and Proterozoic rocks exposed over about 16km2 between Atkins Lake and Coffee Lake in southeastern Bayfield County (Fig. 1) chronicle almost all of the major Precambrian geologic events in the history of the southern Superior Craton. The oldest rocks are part of a locally gneissic quartz monzonite complex, the Puritan Batholith, with an igneous Rb-Sr age of 2710+140 Ma (Sims et...

Environmental baseline study of the Huron River Watershed, Baraga and Marquette Counties, Michigan Environmental baseline study of the Huron River Watershed, Baraga and Marquette Counties, Michigan
This report summarizes results of a study to establish water-quality and geochemical baseline conditions within a small watershed in the Lake Superior region. In 2008, the U.S. Geological Survey (USGS) completed a survey of water-quality parameters and soil and streambed sediment geochemistry of the 83 mi2 Huron River Watershed in the Upper Peninsula of Michigan. Streamflow was measured...

Immediate and long-term fire effects on total mercury in forests soils of northeastern Minnesota Immediate and long-term fire effects on total mercury in forests soils of northeastern Minnesota
Within the Boundary Waters Canoe Area Wilderness in northeastern Minnesota, soils were collected from 116 sites in areas of primarily virgin forest with fire-origin stand years (year of last recognizable stand-killing wildfire) that range from the 1759 to 1976. Median concentrations for total mercury in soils for this span of 217 years range from 0.28 ± 0.088 ppm (1759) to 0.09 ± 0.047...

Total mercury, methylmercury, and selected elements in soils of the Fishing Brook watershed, Hamilton County, New York, and the McTier Creek watershed, Aiken County, South Carolina, 2008 Total mercury, methylmercury, and selected elements in soils of the Fishing Brook watershed, Hamilton County, New York, and the McTier Creek watershed, Aiken County, South Carolina, 2008
Mercury is an element of on-going concern for human and aquatic health. Mercury sequestered in upland and wetland soils represents a source that may contribute to mercury contamination in sensitive ecosystems. An improved understanding of mercury cycling in stream ecosystems requires identification and quantification of mercury speciation and transport dynamics in upland and wetland...

The Sudbury impact layer in the paleoproterozoiciron ranges of northern Michigan, USA The Sudbury impact layer in the paleoproterozoiciron ranges of northern Michigan, USA
A layer of breccia that contains fragments of impact ejecta has been found at 10 sites in the Paleoproterozoic iron ranges of northern Michigan, in the Lake Superior region of the United States. Radiometric age constraints from events predating and postdating deposition of the breccia are ca. 1875 Ma and 1830 Ma. The major bolide impact that occurred at 1850 Ma at Sudbury, Ontario, 500...
