10 Questions
What is the characteristic of 'second-layer geology'?
The first and second layers are totally different and have structural attitudes that may not be related
In which scenario can surface structural studies be used to locate deeper structures?
When the surface and subsurface structure are similar due to the first-layer geology
What is the purpose of a subsurface structural map?
To illustrate the present subsurface attitude and disposition of a chosen datum horizon
What led to the extraordinary success in oil finding by surface structural methods?
Oil fields were found in subsurface rocks whose attitude and dips were the same as those mapped in the surface rocks
How can structures in 'second-layer geology' often be located?
There is no surface manifestation of the deeper structure, and therefore surface structural studies could not be used to locate this deeper structure
Subsurface structural maps are always constructed on the surface rocks.
False
Oil fields were found in subsurface rocks with different attitude and dips than those mapped in the surface rocks.
False
The first and second layers of geology have structural attitudes that may not be related.
True
Surface structural studies can be used to locate deeper structures in 'second-layer geology'.
False
An unconformity separates the two layers of geology in 'second-layer geology'.
True
