Franczyk, Ian P. Madin, Carlie J. M. Duda, and Jason D. McClaughry http://www.oregongeology.org/ Compiled isotopic age analyses are included in the geodatabase. This feature class does not have any cartographic representations associated with its features. This feature class represents the point locations where isotopic age has been obtained for the rock sample in Oregon. 2020 Publication Complete None planned -124.632455 -116.441283 45.984849 41.914307 ISO 19115 Topic Category geoscientificinformation Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus geologic map geology geochronology radioactive element K/Ar Ar40/Ar39 Pb/U Rb/Sr radiometric age radiometric dating radioisotope USGS Thesaurus isotopic analysis Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus North America United States of America Oregon Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus Recent Cenozoic Quaternary Holocene Pleistocene Tertiary Pliocene Miocene Oligocene Eocene Paleocene Mesozoic Cretaceous Jurassic Triassic Paleozoic Permian None MAP DATA: This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes.

Oregon Department of Geology and Mineral Industries jpeg image (.jpg) Supported for release 7 by the Oregon Geospatial Enterprise Office, Framework Development Program. Unclassified Care was taken to limit categorical attribute errors. Attribute accuracy of the database was visually inspected but despite the checks there may be some attributes that are still mislabeled. Many of the sources these data are compiled from include data that has been republished as part of further research or previous compilations. This led to a large number of duplicated datapoints during the initial compilation of the Radiometric Age Information Layer for Oregon (RAILO). Although this database is intended to be free of duplicated values, the complete accuracy of this process cannot be assured. It is important to note that there are numerous points within the feature class that share a location, but due to significant differences in the age date reported, as well as other attributes, these datapoints were determined to not be duplicated. All other fields were populated to various degrees depending on available information. Not all existing attributes were applicable to this schema, and therefore were not included. The source data, RAILO-1, used many different sources variable in age and scale in its compilation. Therefor it has a highly variable horizontal positional accuracy throughout the state of Oregon. Refer to the original source data for positional accuracy.
