Collection of paper reports comprised mainly of IGS publications. A complete list of scanned publications can be found: https://www.iihr.uiowa.edu/igs/publications/search.
thumbnail
This collection includes approximately 4,000 thin sections of rock units from across the state. There are significant Iowa-based thesis/dissertation and paleontological components. The collection includes approximately 1,200 slides for clay mineralogy of Quaternary units. The collection requires a proper database. We are hoping to incorporate into GeoSam, our overall geologic database and web outlet (https://www.iihr.uiowa.edu/igs/geosam/home).
thumbnail
The Field Notes collection mainly consists of hand-written descriptions of outcrops, measured sections, gravel pits, and other geologic sites in Iowa. The majority of these notes were contained in paper files, organized by county. Pertinent information from the files was entered in the GeoSam database and associated documents were scanned and uploaded for public view.
thumbnail
This collection documents LAS files associated with various borehole geophysical logs saved at the IGS. The collection may contain LAS files created while “logging” a well or by digitization of historic geophysical logs.
thumbnail
The dataset consists of more than 3,000 sites in Iowa that contain detailed, regional alluvial stratigraphic nomenclature. The dataset is comprised of boring, dug pit, and cutbank descriptions predominately from the Iowa Office of the State Archaeologist, but also from other alluvial studies, including those conducted by the IGS. The majority of these descriptions were first published in documents from the 1990s, but also included data collected in the 1970s and 1980s.
thumbnail
This collection contains samples primarily from outcrops, quarries, road cuts, shallow Quaternary and soils borings. The unit of measure is 3" Core boxes (3 1/2" x 18" x 24").
This collection houses the results of laboratory analyses of different geological material. Analysis results may include: grain size, radiocarbon dates, clay mineralogy, pXRF, soil carbon and nitrogen, matrix carbonate, bulk density, and clast lithology data.

thumbnail
This collection contains unpublished, working maps, and cross-sections from a wide range of projects. Some of the documents date back to over 50 years ago. Many of these documents are scanned.
This collection houses well logs and construction data for water wells, exploration holes, gas storage structures, geotechnical borings, etc. The collection includes but is not limited to: drilling logs, down-hole geophysical logs, and striplogs (lithologic and stratigraphic logs produced by the IGS). This collection represents data from paper files that complement our cuttings/core collections. Together, they comprise much of the basic, raw geologic data for the state.
thumbnail
This collection includes rock cuttings primarily from public and private water wells. Public water supplies are required to submit cuttings while private well cuttings are received on a voluntary basis. The cuttings are collected in partnership with water well drillers, but also oil/gas companies, mineral companies, geotechnical firms, and other partners.
thumbnail
This collection includes rock cores from oil & gas exploration, public and private water wells, etc. IGS GeoCore tracks cores in the IGS Rock Library. GeoCore stores depth intervals, storage location, and high-resolution photographs for each core stored.
This collection houses wells with electronic records of the information present on paper striplogs in the IGS archives.
