Evaluating pXRF instrument performance using reference materials
The portable X-Ray Fluorescence (pXRF) instrument provides fast, real-time, non-destructive, multi-element geochemical data (i.e. elemental concentrations) on rocks and minerals at a relatively low cost and with minimal sample preparation. This study quantifies the precision and accuracy of measurements collected by the WGNHS pXRF on reference materials...-

Depth-to-Bedrock Mapping in Wisconsin
Depth-to-bedrock maps show the thickness of unconsolidated materials overlying bedrock. These maps provide a key link between the underlying geology, groundwater flow, and land use and are important in guiding activities such as permitting, bridge construction, and the land application of waste products in sensitive areas. Given their role in guiding... -
2018 Year in Review
An overview of some of the projects worked on by the Wisconsin Geological and Natural History Survey in 2018. -
2017 Year in Review
In 2017, Survey staff worked in 69 Wisconsin counties. We mapped geology, inventoried springs, and created groundwater models. We provide natural resource managers – land and water conservationists, county boards, and water utilities – with the information they need to protect and share their resources. This publication provides a summary of some of the... -

Wisconsin's Geologic Past
At different times in the past three billion years, mountains and volcanoes stood tall in Wisconsin, shallow seas covered much of the state, and glaciers plowed across the landscape. This educational poster vividly brings our past to life. Ideal for classrooms. Size: 27 x 39 inches. -
