What is marble marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.It is composed primarily of the mineral calcite caco 3 and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is.

The accumulation of gypsum on carbonate stone has been investigated through exposure of fresh samples of limestone and marble at monitored sites, through examination of alteration crusts from old buildings and through laboratory experiments.Several factors contribute to gypsum accumulation on carbonate stone.
Fresh marble and limestone samples exposed at monitored exposure sites present conditions of simple geometry and well-documented exposures but have short exposure histories one to five years.The gypsum alteration crusts that develop on these samples provide insight into the early stages and rate of alteration crust formation.
