# Geologic Map of the Van Buren North Quadrangle, Carter, Reynolds, and ShannonCounties, Missouri

### By D.J. Weary and R.E. Weems          

|  |   | Abstract
The bedrock exposed in the Van Buren North quadrangle, Missouri,                comprises Mesoproterozoic rhyolite and Late Cambrian and Early                Ordovician aged dolomite, sandstone, and chert. The sedimentary                rocks are nearly flat-lying except where they are adjacent to                faults. The carbonate rocks are karstified and the area contains                numerous sinkholes, springs, caves, and losing-streams.   This map is one of several being produced under the U.S. Geological Survey  National Cooperative Geologic Mapping Program to provide geologic data applicable  to land-use problems in the Ozarks of south-central Missouri. Ongoing  and potential industrial and agricultural development in the Ozarks region  has presented issues of ground-water quality in karst areas. A National  Park in this region (Ozark National Scenic Riverways, Missouri ) is concerned  about the effects of activities in areas outside of their stewardship on the  water resources that define the heart of this Park. This task applies geologic  mapping and karst investigations to address issues surrounding competing land  use in south-central Missouri. This task keeps geologists from the USGS associated  with the park and allows the Parks to utilize USGS expertise and aid the NPS  on how to effectively use geologic maps for Park management.
