[b]reverse fault[/b]--->逆断层（断层面倾角大于45度）

A type of fault formed when the hanging wall fault block moves up along a fault surface relative to the footwall. Such movement can occur in areas where the Earth's crust is compressed. A thrust fault, sometimes called an overthrust if the displacement is particularly great, is a reverse fault in which the fault plane has a shallow dip, typically much less than 45o.

[b]thrust fault[/b]--->逆冲断层（断层面倾角小于45度）

A type of reverse fault in which the fault plane has a very shallow dip, typically much less than 45o. The hanging wall fault block moves up the fault surface relative to the footwall. In cases of considerable lateral movement, the fault is described as an [b]overthrust fault（逆掩断层）[/b]（即推覆构造）. Thrust faults can occur in areas of compression of the Earth's crust.


陆克政主编的《构造地质学》上讲：推移距离在10km以上、倾角极其平缓的巨大逆掩断层就称之为推覆构造、推覆体、辗掩构造


在我们学的课本上，逆断层是个统称，你上面说的对，逆断层包括逆冲断层（低角度逆断层），也就是说，我们在课本上学到的是，不论断层面倾角是多少度，只要上盘相对下盘向上滑动就称为逆断层。然而在实际应用过程中，我们通常所说的逆断层都指的高角度逆断层，而对于低角度逆断层多数称逆掩断层。这是中文表达方面不严谨的一个表现，而在英文中就有明确的区分，高角度逆断层就是Reverse Fault，低角度逆断层就是Thrust fault，理解了这一点，我想在看外文文献的过程中，头脑中就可以有一个清晰的概念，而不至于因为“两者都是逆断层为什么还要用不同的词汇表示”而弄混。
