VIEQUES.STP is a binary file of chemical data for Isla de Vieques
PRNEW.STP is a binary file of 1991 chemical data for Puerto Rico
PROLD.STP is a binary file of 1975-1985 chemical data for Puerto Rico
STP2DAT.EXE is a conversion program from "STP" data file to other commonly
            used data files (DBF, CMN, PST, DIF, and others).

The data tables (*.STP) can be converted into several formats, including DBF, DIF, and ASCII by using the program STP2DAT, authored by W.D. Grundy of the USGS.  This program is included on this disk.

This disk contains geochemical data from 2560 stream sediment samples collected in Puerto Rico, 421 soil samples collected on Isla de Vieques, and 45 soil samples were collected on Isla de Culebra.  Each rock sample was analyzed for 35 elements by a semiquantitative spectrographic method and for gold and zinc by other chemical methods.  Requirements: IBM PC or compatible, 1.2 megabyte disk drive, and a minimum 512K RAM.
