Provided here is a brief description of the files contained within Appendix D. Files 
ending in '.stp' are input files to 'Stp2dat.exe' which converts these files to other 
output formats. The files ending in '.dbf' are dBase files of the chemical analysis of 
data contained within the 'stp' files.


Culebra.dbf		a dBase file of chemical data for Isla de Culebra
Culebra.stp		a binary file of chemical data for Isla de Culebra
Prnew.dbf		a dBase file of 1991 chemical data for Puerto Rico
Prnew.stp		a binary file of 1991 chemical data for Puerto Rico
Prold.dbf		a dBase file of 1975-1985 chemical data for Puerto Rico
Prold.stp		a binary file of 1975-1985 chemical data for Puerto Rico
of92-353.pdf		text of USGS open-file report 92-353 in PDF format
stp2dat.exe		a conversion program from 'STP' data format to other commonly 
				used data formats (dbf, cmn, pst, dif, and others)
vieques.dbf		a dBase file of chemical data for Isla de Vieques
vieques.stp		a binary file of chemical data for Isla de Vieques

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.
