5.1 Formation

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Rhomb-porphyry is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
