What is the characteristic of 'second-layer geology'?
What is the characteristic of 'second-layer geology'?
- The surface reflects the subsurface attitude of the beds
- The deeper structure has a surface manifestation
- The surface and subsurface structure are similar
- The first and second layers are totally different and have structural attitudes that may not be related (correct)
In which scenario can surface structural studies be used to locate deeper structures?
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 (correct)
- When an unconformity separates the two layers of geology
- When the first and second layers have totally different structural attitudes
- When there is no surface manifestation of the deeper structure
What is the purpose of a subsurface structural map?
What is the purpose of a subsurface structural map?
- To illustrate the present subsurface attitude and disposition of a chosen datum horizon (correct)
- To analyze the historical surface geological events
- To determine the chemical composition of subsurface rocks
- To predict the future subsurface geological events
