using grass for GEOLOGY

[Simon Cox]

We are interested in using grass as a geological map compilation tool.  
I wonder if anyone else has any experience with this?  

One set of programs which I was thinking would be useful would be some 
structural data projections - eg stereographic projections of orientation 
data which could be selected from a database using a combination of 
spatial and attribute queries (rock type, location mask, etc).  

Before I go ahead and try to implement this, I wanted to hear 
from anyone else who may have done the same thing.   Any takers ???

Thanks
