Question

Quizplus · Accepted Answer

Calcite is a mineral that is highly susceptible to chemical weathering by dissolution. It reacts readily with weak acids, such as carbonic acid, which is commonly found in rainwater. As calcite dissolves, it can weaken the rock it is a part of or be completely dissolved, leaving holes and voids in the rock. Clay minerals, iron oxides, and quartz are not as susceptible to dissolution.
