from The Century Dictionary and Cyclopedia
- n. In geology, a type of reversed fault where, as the result of enormous tangential pressure, the rocks on the upper side of the fault have been pushed or thrust for a greater or less distance, with an entire severance of continuity, over the, underlying masses. The line of junction of the dissevered parts in such cases is denominated a thrust-plane.
Sorry, no etymologies found.
The part of the thrust-plane over which movement took place must therefore have been about 200 miles long, not less than 50 miles wide, and between 6000 and 7000 square miles in area.
