Digital geologic map of the Elizabethtown Quadrangle, Essex County, New York

Digitized shapefiles representing surface geologic features depicted in Matthew S. Walton's unpublished 1960 geologic map of this area. Includes geologic units representing Precambrian basement rock, geologic structures, diabase dikes, mine shaft locations, and water bodies. Data are provided in shapefile and GeoTiff formats. Notes from the original map are provided in PDF format.

Magnetotelluric data from Missouri, Arkansas, Tennessee, Illinois, and Kentucky, 2016-2019

Magnetotelluric station data collected from 2016-2019 across parts of Missouri, Arkansas, Tennessee, Illinois, and Kentucky to support regional investigations into the geologic and tectonic framework of the area and mineral resource and geologic hazard investigations.

USGS Spectral Library Version 7 Data

Spectra measured with laboratory, field, and airborne spectrometers. The instruments used cover wavelengths from the ultraviolet to the far infrared (0.2 to 200 microns). Laboratory samples of specific minerals, plants, chemical compounds, and man-made materials were measured. In many cases, samples were purified, so that unique spectral features of a material can be related to its chemical structure. Data are provided in text format as well as the SPECtrum Processing Routines (SPECPR) format.
