RAILO-1 is a compilation of 2,325 radiometric ages from published and unpublished reports by the Oregon Department of Geology and Mineral Industries’ (DOGAMI), along with additional data compiled from other sources such as the U.S. Geological Survey (USGS) and the journal Isochron/West. The compiled ages range from 0.00005 million years to 291 million years.
RAILO-1 is provided in Microsoft® Excel® spreadsheet and Geographic Information System (GIS) geospatial database formats. The location of each data point shown in this map was not necessarily verified; refer to the original data source for additional information about location and location uncertainty. Duplicate points were removed when found. This map also includes a list of data sources (references) from which the age information was gathered.
