如何确定这个错误是正常的,左旋?

明天准备考试呢,栽倒在这个问题(部分 e d 和 )。 < blockquote > 区域显示在图2由一系列的沉积地层,倾斜的侵蚀,产生一个不整合。熔岩流的不整合覆盖,该地区经历了进一步倾斜,然后断裂之前侵蚀改变了平原地区。使用图2提供的数据确定 。数量的净滑 b。耙的净滑断层计划 c。跳水和趋势的净滑 d。relative movement along the fault e. type of fault

The original answer for d & e was that the eastern block moved NW relative to the western block, and it was a sinistral reverse fault. Can't remember why I chose reverse and not normal.

Lab TA appears to be saying not sinistral, just 'normal'.

So my questions are, how would you determine that it's a normal fault and not reverse? Why not sinistral?

I can't see an indication of how the foot wall (western block) has moved relative to the hanging wall. I know the TA is the person to ask but it's an online course and answers were slow to come at the best of times.

所以,基本的地质历史。从这个单位叫床1沉积,然后倾斜。床2沉积和倾斜(连同床1)。整个序列被指责。 ,我们怎么能告诉什么故障吗? 首先,注意到有块西北东部的运动。这可以推导出因为所有的联系人已经在这个方向转移。 ,让我们转向西北的撤销: < img src = " https://dl.dropboxusercontent.com/u/17444491/geology/x9wMl_2.png " alt = " " > 现在,我们可以看到,接触床2和床1不排队。这意味着我们必须有向上或向下运动。这个工作的唯一方法是通过了解接触的下降。如果它一直向北,东块上升。如果它下降,那么它将躺在所有的沉积物。 This suggests that Bed 2 dips northwards.

Upward movement of the eastern block would then reveal Bed 1 when the area was eroded.

My conclusion therefore, is that the fault moved the eastern block north-west and up, relative to the western block.

Did I miss anything? It is late, which I will claim as an excuse. If my logic is unclear, let me know and I can try add more pictures, or video of me waving hands about, which is my usual approach.
