Preliminary Investigation of Selected Samples of Varnished Rock from the Baluco Surface, Vicinity of Proposed Low-Level Waste Site Near Ft. Hancock, Texas

This report summarizes work conducted from March to June of 1989 in the preliminary investigation of varnished rock samples under consideration for AMS radiocarbon dating (Dorn, in press). The report is divided into three sections: (1) description of samples, (2) summary of discussions with Dr. Ronald I. Dorn, Arizona State University, and (3) summary of total organic carbon (TOC) determinations. Ultimately, it was concluded that the varnish on these samples is not well enough developed to yield reliable results, and as a result, the work was terminated.
