A buried body of shale is subjected to differential stress at temperatures greater than 200ºC,causing clay minerals to grow in preferred orientation and producing slate.This is an example of ____________.
A) diagenesis
B) erosion
C) metamorphism
D) weathering

Question

Quizplus · Accepted Answer

The process described in the question involves the transformation of shale into slate under high temperatures and pressure, which is a typical example of metamorphism. Diagenesis refers to the physical and chemical changes that occur in sedimentary rocks before lithification, while erosion and weathering are processes that involve the breakdown and transportation of rock materials.
