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...

This collection is comprised of all field samples collected by the U.S. Bureau of Land Management Non-fuel solid mineral branch and the former U.S. Bureau of Mines housed at the Alaska Geologic Materials Center in Anchorage, Alaska. This collection represents the entirety of the BLM Alaska rock collection, totaling 117476 samples consisting of many sample types from core, hand, pan concentrates, stream sediments, thin sections, pulp and other miscellaneous sample types

This collection consists of samples with age data and associated information for available radiometric dates for rocks and minerals in Alaska. The sample records and their associated publications were loaded into the Alaska Division of Geological and Geophysical Surveys division-wide database. A legacy Microsoft Access database exists that includes dates for all available U-Pb, K-Ar, 40Ar/39Ar, and Rb-Sr data for Alaska through 2007. Previous compilations by Wilson and others (1990) and U.S. Geological Survey (1999) provided the initial source of age data. Additional radiometric dates were compiled from both published and unpublished sources. This legacy project added essential basic supporting information that...

Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members. Samples date from the early 20th century to the 1990s and were collected throughout the state. Many of the samples are described in the historical field notebook collection, and relationships between the samples and the field notebooks have been established and captured in identifiers. Locations for samples were taken from field notes, maps, and accession lists. There are approximately 5,700 hand samples in this collection.

This collection is composed of hand samples, thin sections, geochemical pulps and crushed splits of rock collected by the Alaska Volcano Observatory (AVO), a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the Alaska Division of Geological and Geophysical Surveys (ADGGS). It includes rocks from AVO field projects as well as samples collected by AVO-supported graduate students as part of our efforts to better understand eruptive processes and mitigate eruption hazards. It is estimated that there are about 30,000 samples in this collection. The Alaska Division of Geological and Geophysical Surveys division of AVO has no direct...

The Geologic Materials Center (GMC) Data Report collection contains analytical and interpretive data resulting from testing by third parties on material donated or borrowed from sample materials housed at the Alaska Geologic Materials Center. These reports are produced by the third party agency or company that conducted the sampling and analysis, and in some cases, interpreted results. The reports have not undergone technical peer review and should not be used or cited as reviewed data.

Minnesota Geological Survey is working with partners to build a statewide, consistent, standardized, and documented geochemical database, due to the convergence of: 1) systematic sampling & analysis of soils and stream sediments by the USGS & the MGS; 2) completion of a statewide till geochemical survey by MGS in cooperation with industry, and 3) renewed efforts by Minnesota Pollution Control Agency (MPCA) to ensure optimal usability of their state ground-water chemistry data. The soil/sediment data are distributed statewide, were collected over a short period of time, and samples from each project were analyzed by the individual labs following consistent and documented protocols, while the MPCA water analyses were...

The legacy thin section collection represents petrographic thin sections collected by DGGS geologists for field projects involving geologic mapping in areas of Alaska with a focus to study the potential and controls of mineral and energy resources. As part of the mapping process, rocks were collected for petrographic work to provide information for discriminating between various rock types and to write unit descriptions of the final rock types or units represented on geologic maps resulting from the field work. The collection represents 27 years or more of work and over 15,000 outcrop thin sections from all over Alaska and a wide variety of field geologists. Samples are housed in various locations within the DGGS...
