Releases airborne survey data, resistivity cross-sections and depth slices derived from data inversion. Resulting resistivity models confirm geologic framework, constrain hydrostratigraphy and depth to basement, and reveal fault and fold distribution.
Geological and borehole geophysical data and observations collected to characterize the basin and its surface and groundwater flow systems with primary focus on the physical characteristics of the fault vein, related mine workings, and surrounding bedrock
Flight-line data and gravity grids with documentation.
This report summarizes the assembly of pertinent data, determination of its limits, analysis of its properties, and the relations among the different data types in preparation for future modeling.
Discusses the physical properties of frac sand, its geologic origin and formation contributing processes, its use in industry, consumption history and a global outlook. US / Canadian producers are detailed and potential other sources delineated in a GIS
Groundwater geochemistry data from samples that were collected in June 2011 to better understand the hydrogeologic system in the area surrounding the proposed mine site.
To help understand the hydrogeologic controls in the basin and how they affect surface and groundwater interactions with nearby mine workings, electrical resistivity profile, self–potential, and magnetic measurement data are provided herein.
The objective of the survey was to improve the understanding of the relationship between surface water and groundwater systems critical to developing management programs for water resources.
Geophysical surveys to map shallow hydrogeologic features of the southwestern part of the Sand Hills that contain a mix of fresh to saline lakes.
The objective of the contracted survey was to improve the understanding of the relation between surface water and groundwater systems critical to developing groundwater models used in management programs for water resources.
Ground- and surface-water samples were collected in order to characterize the local ground-water flow system, determine metal concentrations in local ground water, and understand factors controlling the discharge of metal-rich waters from the mine.
This report describes key features; identifies tectonic-sedimentary environments; illustrates geochemical, geophysical, and geoenvironmental characteristics; evaluates deposit formation; presents exploration and assessment guides; and lists knowledge gaps
This report releases data, cross section, and model information related to the identification of travel paths for groundwater supply and principal stratigraphic and structural features that serve as constraints or conduits for groundwater movement.
