The Lake Bosumtwi meteorite impact structure, Ghana A magnetic image from a third observational level

Abstract

The Bosumtwi impact structure in Ghana is the youngest and best-preserved medium-sized impact structure on Earth, and because of the vast amount of prior geophysical and geological data gathered in the area, it constitutes a great natural laboratory to try to develop new geophysical interpretation and modeling techniques. During the 2004 International Continental Scientific Drilling Program (ICDP) drilling campaign at highlight of this study is that we demonstrate that is possible to acquire at least partial vector data with readily available instrumentation.
