The files in this directory are dBase files, translated from the entire set of fault attribute tables in Info format.  The numerical keys match the integer data types of the original Info data set, and can be linked with the user-ids ("covername"_) of the GIS data set using MapInfo, ArcView or other GIS software.

In addition to fault data tables,this directory contains a full description of the table structure and contents in table form.  This database description begins with a catalogue of all of the tables and their uses in 'ftct.dbf'.  Links between tables are described in 'ftlinct.dbf'.  The fields in data tables are described in tables named using the first six characters of the data tables name followed by df and the extension '.dbf'.  Data tables themselves are named with the first up to six letters of the info table name followed by a 'dt.dbf'.  Allowable values for each non-numeric field are given in tables beginning with the first six letters of the field name followed by 'pt.dbf'. These value tables are named in the field description tables.Lookup tables, notably agetsmlt.dbf (geological age terms), contain the letters 'lt' at the end of the six letter prefix.


The lookup table agetsmlt for geological age terms was derived, mainly, as indictaed by the initials WBH in the field SOURCE, from:

Harland, W. B., Armstrong, R. L., Cox, A. V., Craig, L. E., Smith, A. G., and Smith, D. G., 1990, A geologic time scale, 1989, Cambridge University Press, 263 pages.

This was for the sake of the thorough list and documentation provided by the reference, but new IUGS calibrations will be adopted when they are officially accepted. 

Several more parochial terms (used mainly in mineral deposit databases) were obtained from:

Okulitch, A. V., 1995, Geological time scale, 1995, Geological Survey of Canada, Quality Color Press, Edmonton, Open File 3040, 1 p.
