Three dimensional digital analysis of 2,500 square kilometers of gravity and magnetic survey data, Bellefontaine Outlier area, Ohio

Introduction The Bellefontaine Outlier area is a highland region of flat lying Devonian age rocks capped by varying amounts of glacial till. The area is entirely surrounded by a topographically flat and heavily glaciated area of flat lying older Silurian age rocks. The Outlier highlands also contains the highest point in Ohio, Campbell Hill, (1,549ft) which has an elevation 40 feet above it the ...

Landstreamer

The Landstreamer LS-24 is used to record P-, S- or surface waves. The landstreamer is suitable for MASW or reflection seismic applications, especially on paved ground. It consists of several horizontally or vertically oriented sensors mounted on sledges which are attached to a robust belt. The belt can be hooked to a vehicle and moved along the profile. A landstreamer is used to collect a large ...
