This map set contains unpublished maps, cross- sections, and related information archived by the State Geological and Natural History Survey of Connecticut as part of the Survey Library Collection. These materials have not been reviewed for accuracy, consistency, or completeness. For many geographic areas, more current information exists, either in published or unpublished form. For the most part, these materials were developed under research and mapping agreements between the State Geological Survey and individual scientists, academic institutions, or graduate students. Some of these materials have been received by the State Geological Survey as donations. The veracity of the information contained within these...
As coal companies closed business in Indiana many times they deposited their records at the Indiana Geological Survey (IGS). The records in most cases were delivered in boxes or full filing cabinets without documentation. The IGS has preliminarily sorted through the records filing them by company and if possible county or Township-Range to make them discoverable. The records can contain anything from maps, analysis, logs with or without picks, descriptions, correspondence, etc.

Most projects conducted by the MWRA have attached to them a geotechnical report and accompanying environmental information. There are also eighteen marine drilling reports on work in the Boston Harbor, as well as, two hardbound copies on the Geology of the Waschusett Reservoir Area. All reports are stored in the library at the main facility in Chelsea; however, not all project managers turn over reports to the librarian for storage. Most projects conducted by the MWRA, related to the construction of water and sewer lines, have attached with them, a geotechnical report and accompanying environmental information. Other paper reports include: eighteen marine drilling reports from work in Boston Harbor; as well as two...
Collection includes cores extracted over decades by mineral exploration firms as they completed their Maine work or otherwise released their data, covering both public and private lands that were the subject of mineral exploration. These records represent the best public collection of the major mineral exploration efforts of the 1960s-1980s. This collection of 595 scanned core records is accessible through a Google Earth application. Please contact the Maine Geological Survey to discuss access to the collection.

The current component databases of NCRDS include: USTRAT: Stratigraphic data related to coal (e.g. drill holes, measured sections) USCHEM (COALQUAL): Ultimate, proximate, and USGS-generated major-, minor-, and trace-element data for coal samples collected by USGS and States. USCOAL: A historical database of coal resource estimates compiled from publications prior to 1978 The collections referenced here are for historical purposes. The most current and up-to-date coal information is available electronically...
