Coal mine drainage effluents and associated solids major, trace, rare earth element and radium concentrations collected from Pennsylvania, USA Coal mine drainage effluents and associated solids major, trace, rare earth element and radium concentrations collected from Pennsylvania, USA
Discharges from abandoned coal mines and associated mine wastes represent historic and persistent sources of pollution in the Appalachian Basin, United States. In this study, we conducted the first-ever survey of radium (Ra) in coal mine drainage (CMD) water and solid samples in the United States. Samples were collected from 4 untreated coal mine discharges and 9 treated coal mine...
Mineral resource assessment of rare-earth elements, thorium, titanium, and uranium in the Greenville 1° x 2° quadrangle, South Carolina, Georgia, and North Carolina Mineral resource assessment of rare-earth elements, thorium, titanium, and uranium in the Greenville 1° x 2° quadrangle, South Carolina, Georgia, and North Carolina
Mineral resources of the Greenville 1° x 2° quadrangle, South Carolina, Georgia, and North Carolina, were assessed between 1984 and 1990 under the Conterminuous United States Mineral Assessment Program (CUSMAP) of the U.S. Geological Survey (USGS). The mineral resource assessments were made on the basis of geologic, geochemical, and geophysical investigations and the presence of mines...
A geochemical investigation of selected areas in Greenville and Laurens Counties, South Carolina: Implications for mineral resources A geochemical investigation of selected areas in Greenville and Laurens Counties, South Carolina: Implications for mineral resources
The purpose of this study is to geochemically evaluate three areas within the Greenville 1° x 2° quadrangle (see index map) that have been shown by previous studies to contain anomalously high amounts of tin. Jackson and Moore (1992) reported the presence of cassiterite (SnO2)-bearing heavy-mineral concentrates from stream sediment samples that were collected during a regional...

Evaluation of coal mine drainage and associated precipitates for radium and rare earth element concentrations Evaluation of coal mine drainage and associated precipitates for radium and rare earth element concentrations
Coal mine drainage (CMD) and associated metal-rich precipitates have recently been proposed as unconventional sources of rare earth elements (REEs). However, the potential occurrence of radium (Ra), a known carcinogen, with the REE-bearing phases has not been investigated. We hypothesized that Ra may occur in solids that are precipitated from CMD as a “radiobarite” solid solution ((Ba,Sr...

The Mississippi River: A place for fish The Mississippi River: A place for fish
The Mississippi River flows 3,734 km from its source at Lake Itasca, Minnesota to its outlet at the Gulf of Mexico. Along its course, it collects water from portions of two Canadian provinces and 41 % of the conterminous United States. Although greatly altered for navigation and flood control throughout much of its length, the Mississippi River remains an important fishery resource that...

Coesite in suevites from the Chesapeake Bay impact structure Coesite in suevites from the Chesapeake Bay impact structure
The occurrence of coesite in suevites from the Chesapeake Bay impact structure is confirmed within a variety of textural domains in situ by Raman spectroscopy for the first time and in mechanically separated grains by X-ray diffraction. Microtextures of coesite identified in situ investigated under transmitted light and by scanning electron microscope reveal coesite as micrometer-sized...

Monoclinic tridymite in clast-rich impact melt rock from the Chesapeake Bay impact structure Monoclinic tridymite in clast-rich impact melt rock from the Chesapeake Bay impact structure
X-ray diffraction and Raman spectroscopy confirm a rare terrestrial occurrence of monoclinic tridymite in clast-rich impact melt rock from the Eyreville B drill core in the Chesapeake Bay impact structure. The monoclinic tridymite occurs with quartz paramorphs after tridymite and K-feldspar in a microcrystalline groundmass of devitrified glass and Fe-rich smectite. Electron-microprobe...

Characterization of rock samples and mineralogical controls on leachates Characterization of rock samples and mineralogical controls on leachates
Rocks associated with coal beds typically include shale, sandstone, and (or) limestone. In addition to common rock-forming minerals, all of these rock types may contain sulfide and sulfate minerals, various carbonate minerals, and organic material. These different minerals have inherently different solubility characteristics, as well as different acid-generating or acid-neutralizing...
