DATA DESCRIPTION: 

This file is contains clay mineralogy, Nd/Sm and Pb isotope data from
possible source regions for GISP2 dust, from Biscaye et al.  (1997). 
Details are given in the reference and in the file gisp2min.dat.  '999999'
refers is used for non-measured parameters.

Data on possible dust source regions are given in the companion file 
gisp2min.dat.
