Gene,

Can you you briefly describe 'overthrust' and 'sill' for me?


Butting in, for lack of anything better to do in my life -

See "sill" and "thrust fault" at:
http:///WebPages/Glossary_Geology.html

Essentially, a sill is an intrusive igneous rock body, that superficially mimics a volcanic flow.

A thrust fault is such that, it is possible for older rock layers to be physically moved to be on top of younger rock layers (opposite of the normal superposition). The upper rocks (the upper plate of the fault) are "overthrust" over the lower rocks (the lower plate of the fault).

Regards,
Moose
