Question

cross sectional views.
place the layers and events in an order of time relative to each other using the relative dating principles
begin with the older later and work your way to the youngest layer.
then answer the questions


Events youngest Ufult 8. Describe the fault type for faults D and R: oldert 9. What type of unconformity is erosion L? Events youngest 10. Intrusion W is what type of intrusion? oldest 11. How can you tell which came first, For Z? 12. What is the fault type for fault V? 4 of 7

Explanation / Answer

The arrangement of the events of First Image on the basis of older to the younger event:

Answer 8:

The fault D has a curved fault line, whose hanging wall has moved downward side relative to its footwall. Therefore, fault D is a Listric normal fault.

Where the hanging wall of fault R has moved upward side relative to its footwall along its fault plane. So, fault R is an example of Reverse fault.

Answer 9:

The erosion L is an example of Disconformity because the layers above and below of this erosional surface are more or less parallel to each other. The deformed beds are showing an angular nature but according to the genesis and stratigraphy, this erosional line must be a Disconformity.

The arrangement of the events of First Image on the basis of older to the younger event:

Answer 10:

Intrusion W is a Dike intrusion which crosscut all the pre-existed layers.

Answer 11:

Rockbody F came first then rock body Z; because according to the stratigraphy of the area rock body F came first then subsequently the layers G, X, D, and R and then the fault deformation took place. After this, rock body Z intruded otherwise it was also affected by fault V.

Answer 12:

Fault V is a Reverse fault because its hanging wall has moved upward side relative to its footwall along the fault plane.
