Abstract
This research project is to develop a system and conduct complex resistivity (cr) surveys using state-of-the-art instruments and interpretation methods at Mississippi Valley type (MVT) deposits in the viburnum trend or old lead district in southeastern Missouri. Analysis of combined surface and borehole measurements should allow the building of two-dimensional images of the geo-electrical cross section through the ore bodies. From the geo-electrical sections, major geological structures and massive and disseminated sulfide distribution can be inferred. During the project the need for such a system became increasingly obvious. We found the exploration areas are now commonly nearly 2,000 ft deep. This exceeded the design limits of the system that we were developing, and within the time and budget constraints of the present project we were not able to conduct field survey at a mining site. We did conduct field trials of the system at two shallower sites: one at rechtein farm and one at oyo corps cross-borehole resistivity test site in southeast Illinois. These sites have taught us a great deal about the design of a cross-borehole system.
