查看答案
Fault gouge is very fine-grained, unconsolidated material consisting of pulverized rock fragments.
A slickenside is a smooth, striated, polished surface and can be used to determine the direction and sense of motion on a fault.
A joint is a crack along which there has been no appreciable movement, while fault is a fracture with relative movement of the rocks on both sides of it, parallel to the fracture.
Folds can also be classified into non-plunging fold and plunging fold according to the orientation of hinges.
