Introduction

Basic research on the state's geologic framework and history is the work of the Division's geologists. These duties include geologic mapping, studies or rock layers and structure, ancient environments and ancient life, as well as analysis of test drilling, geophysical data and minerals to help evaluate land and water resources. These studies determine factors influencing ancient and present environments and provide the basis for applied research such as natural-hazard mitigation, building-site evaluation and minerals exploration.

The Division also maintains an extensive core and sediment sample inventory available for study.

Geological Survey Resources

The following information was originally developed within the Conservation and Survey Division. Due to the merger with the School of Natural Resources (SNR), the information is now housed on the SNR web site. For your convenience, links are provided here:

Other On-Line Data Bases

• Nebraska Oil and Gas Data Base - Administered by the Nebraska Oil and Gas Commission. The Conservation and Survey Division (CSD), now part of the School of Natural Resources, provided the stratigraphic information for this data base.
• Nebraska Registered Groundwater Wells Data Base - Administered by the Nebraska Department of Natural Resources. CSD was responsible for automating the geologic logs portion of this data base.
