穿过阿辛特区的莫因逆冲断层带是个向前陆扩展的薄皮逆冲断层带的典型实例,对于研究与逆冲断层有关的褶皱、变形作用产生的结构和应变,以及研究复杂的增量应变的历史是理想的实例。离散的运动方向、斜向褶皱、双重构造(duplex)带和垂直于主要运动方向的拉伸应变等,全都可以用逆冲断层的扩展来解释,扩展结果引起了斜断坡至断坡的发育。大多数逆冲断层都沿运动方向从基底往上切断盖层,但是还有逆冲席体的局部的拉伸性塑流与变薄。在阿辛特北部,此逆冲断层带包括有一条宽阔的、直立的左旋剪切带,这个剪切带范围内前逆冲断层、后逆冲断层以及伴生的褶皱、劈理等都与总的运动方向斜交。本文提出,在该剪切带以北,那些逆冲断层都运动得更远,很可能是盖在较厚层的下面,而在此剪切带以南。则运动是更加断断续续的,很可能是盖在较薄盖层的下面。这种变化很可能归因于逆冲断层的几何特征。在莫因逆冲断层带以东的莫因系地层里的改变,导致了整个莫因逆冲断层线上重力位能的变化。
The Moing thrust belt that crosses the Assinat area is a typical example of an anterior landward thin-skinned thrust belt that is of great interest in the study of structural and structural deformations associated with thrust faults, deformations and deformations The history of quantitative strain is an ideal example. Discrete directions of motion, diagonal folds, duplex bands, and tensile strains normal to the principal direction of motion, etc. can all be explained by the extension of the thrust fault, which results in the development of ramp to ramp . Most thrust faults cut the cover up from the base in the direction of motion, but there is also local stretch plastic flow and thinning of the body. In the northern part of Hinnit, this thrust zone consists of a broad, upright, left-lateral shear zone within which the pre-thrust, post-thrust and associated folds, cleavages, etc., The direction of the movement of the bias. This paper suggests that those thrusts move further north of the shear zone, most probably underneath a thicker layer, and south of this shear zone. Then the movement is more intermittent, it is likely to be covered under the thin cap layer. This change is likely due to the geometric characteristics of the thrust fault. Changes in the Moier strata east of the Moine thrust zone led to changes in gravitational potential over the entire Moine thrust line.
