Description:
Abstract: The Iowa stratigraphic column consists of rock materials of varying geologic age that have been categorized into a shapefile for summarizing the 3 dimensional aspect of Iowa's geologic framework for water & mineral resouce investigations within the state. This shapefile represents a subset of GEOSAM (Iowa's Geologic Sampling Points) that has geologic data associated with site specific data that may consist of well samples, cores, quarry faces, roadcuts, or river exposures.
Purpose: To be utilized as a point source for geologic interpretations of Iowa geology (both structure and thickness).
Supplemental Information: This digital, geographically referenced data set was developed by the Iowa Department of Natural Resources to carry out agency responsibilities related to management, protection, and development of Iowa's natural resources.

Use Constraints: The development of the coverages in the NRGIS Library represents a major investment of staff time and effort. As a professional responsibility, the the Iowa DNR expects to receive proper credit when these GIS coverages are utilized. The Department also expects that the original documentation will remain with any redistribution of these coverages.

Process Step:
Process Description: This dataset has been filtered to only sites that have xy coordinates and elevation within the GEOSAM dataset, from which an Event theme is created and exported to a point shapefile. Because of the nature of stratigraphic data multiple records per site location are created that then can be filtered by any combination or individually of geologic System, Group, Formation, or Member. Primary, secondary, and tertiary lithologies are also noted and can be filtered against also. Additionally unit elevations and unit thicknesses are recorded for each stratigraphic interval and can be utilizied in the 3D environment.
