Rocks are classified chemically as follows:
- Siliceous rocks: – They are composed mostly of silica (as well as quartz and flint) and are extremely hard and resistant to weathering. Granites, quartzite, traps, and sandstones are the most common siliceous rocks.
- Argillaceous rocks: – Clayey rocks are mostly made up of alumina, with minor amounts of other minerals thrown in for good measure. This category includes slates and laterites.
- Calcareous rocks: – The major component of these rocks is calcium carbonate, sometimes known as lime. Crystalline and compact varieties are tough and long-lasting. Clay is frequently found in such rocks. Calcareous rocks include marbles and limestone.
