Web4. Differential stress (pressure) can cause _______. (A) cause the rocks to partially melt. (B) cause new minerals to grow from the protolith. (C) cause minerals to align parallel to each other. (D) cause minerals to become smaller. 5. Chemically reactive fluids react with protolith to cause. WebStructures in geology are deformation features that result from permanent (brittle or ductile) strain. Stress is the force applied to an object. Stresses can be confining, compression, tension, or shear. Rocks under stress may show strain or deformation. Deformation can be elastic or plastic, or the rock may fracture.
