We have a modified version of the USGS MRDS (Mineral Resources
Data System) global mineral occurrence data base available in a MapInfo format
(TAB or MIFF) on CD for US $40. The cleaned data base contains 101,806 records
(original file had 111,955 records). For those of you who are unaware, about 70%
of the data relates to the Americas. The original database has a lot of problems
(i.e. lots of duplicates and data with no location information and many useless
fields). If you would like to do this yourself I would not recommend it as a fun
pass time, It took about six days and a few knew gray hairs to get it into a
form that we regarded as acceptable. The resultant MapInfo file is just under
250Mb in size.
