The 3002’ length core was extracted from the Redstone Quarry in Conway, NH in 1975 as part of an evaluation of geothermal potential produced by the natural decay of several radioactive minerals present in the Jurassic age Conway Granite pluton. The core extracted from the borehole at the Redstone Quarry is the deepest core drilled in New Hampshire. The Redstone Core project was part of a collaboration between the New Hampshire State Geologist and the U.S. Energy Research and Development Administration. Significant geothermal resources were not found. NHGS estimates that approximately half of the original 3002’ foot core remains in core boxes with sufficient documentation tags to identify the depth intervals each...
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.
Location data for exploratory, sciencific, or engineering borings conducted statwide since the early 1900s. Drill Core and/or other samples from a large number of these borings are stored in the DNR's Drill Core Library in Hibbing, Minnesota. For more information on the drill core library please vist the DNR's webpage: http://www.dnr.state.mn.us/lands_minerals/dc_library.html

Collections of physical samples and data managed and preserved by the U.S. Geological Survey (USGS). The separate collections are managed by different projects and Mission Areas of the USGS. The collections are distributed across the United States, in various USGS offices. Preservation of some of these collections may be supported by the National Geological and Geophysical Data Preservation Program. USGS strives to publicly expose its materials, data, and other research to further scientific inquiry. Points of contact for individual collections may be contacted to request access to materials and data.

The mission of the Colorado Geological Survey is building vibrant economies and sustainable communities, free from geologic hazards, for people to live, work and play through good science, collaboration, and sound management of mineral, energy and water resources. Geoscientific collections managed by Colorado Geological Survey are aggregated in the National Digital Catalog to enhance discovery and use of valuable samples and data for further scientific research. Contact information and material access instructions are provided for the individual collections.
Dataset contains point data describing the results of 1-channel and 12-channel seismic refraction studies mapped at a scale of 1:24,000, from the Maine Geological Survey. The results include the depth to the water and depth to the bedrock. Links are also provided, when available, to the profile graphs for the seismic line.

An FY17 NGGDPP grant funded a demolition project to rescue of 1952+ core boxes from a collapsed building, the Cary Annex. The OTHER Undocumented Core Collections (OUCC) defined herein helps compile the interim results of an inventory of 781 of the 1952+ rescued boxes, funded by an FY21 NGGDPP grant. As a result of the inventory, 277 core boxes were identified that are associated with 63 new, previously undocumented boreholes. All of the boxes were damaged and likely need reboxing; 85 were reboxed by NCGS staff. Some of the core boxes have partial losses of core lengths; some material is weathered in situ (in the box). These collections include HARD ROCK and TRIASSIC geologic core samples. Coordinate data is not...
