Question

Under what conditions was this rock likely deformed? 
A)relatively shallow 
B)brittle conditions 
C)conditions that favored fracturing 
D)all of these

Quizplus · Accepted Answer

The options given in A, B, and C are all conditions that favor brittle deformation. Shallow rocks are more prone to brittle deformation due to lower confining pressure, and conditions that favored fracturing also lead to brittle deformation. Therefore, all the options hint towards brittle deformation which implies that the rock was subjected to brittle deformation conditions. Hence, D - all of the above is the correct answer.
