Redefinition. A thrust isn't just where 'a rock is moved up relarttive to another rock; it is older over younger. Thats what makes it a thrust! A normal fault sees a rock moved up relative to the other rock; the younger rock.
Duplexes. These are important. Few understand them, but that doesn't mean you should edit out what you don't understand. Duplexes are right bastards to recognise, but they are probably heavily under-reported because its much easier to ignore the simple mechanical sense of duplexing: less energy spent stacking. Anyway, just a personal bugbear.
Added the bit about the Moine because I heard it via the Livejournal Geology community. Also added a bit about ramp-flats, to parallel the section in
geologic fault.
Finally, thrusting usually occurs within units, which was missing before this edit. The difference between a reverse fault and a thrust was added based on this principle. Not all reverse faults are thrusts, and its not as simple as the angle, because of the fact of rotation after the fact, nor "steepness" because thrusts very, very rarely are completely planar in any of the three dimensions. See ramp and flat, for instance.

The "History" section mentions "Escher, Heim and Bernard". Shouldn't "Bernard" rather be "Bertrand" ( Marcel Alexandre Bertrand, 1847-1907)? 71.141.118.221 ( talk) 00:25, 26 January 2008 (UTC)
"Because of their low dip, thrusts are also difficult to appreciate in mapping, where lithological offsets are generally subtle and stratigraphic repetition difficult to detect especially in peneplanated areas". 76.95.209.135 ( talk) 23:16, 13 April 2011 (UTC)
Agree. The photo caption for the example of thin-skinned deformation is difficult to understand as well. "Pinches out with distance"? -- 98.114.28.11 ( talk) 01:13, 2 April 2014 (UTC)
This sentence also sounds like it is talking about thrust faults in general and not just blind thrust faults. Perhaps if it is kept it should be moved to the lead in section. HarrisonHuttanus ( talk) 06:37, 24 February 2021 (UTC)
