Calcium carbonate or calcium magnesium carbonate.
Limestone caves are formed through a process called karstification, where rainwater picks up carbon dioxide from the air and soil, creating a weak carbonic acid. This acidic water dissolves the limestone rock over time, creating underground cavities and passages. As the water drains away, it leaves behind caves and unique formations such as stalactites and stalagmites.
Chemical limestone can form when calcite is dissolved.
it rains and sinks into limestone and over to starts to corrode at the vulnerable limestone
Marble is one form of metamorphosed limestone.
limestone forms from skeletons and shells
Limestone can be formed partly or mostly by visible shell fragments. .
Although limestone can form into other types of metamorphic rock, the most common form is marble.
Limestone - sedimentary deposition of calcarious marine organisms. Marble - compressed (metamorphosed) limestone.

Grikes form when limestone is dissolved by water.
The hard and huge mountains are known as lime stone pillars.
Chert, a form of quartz, can form as beds or nodules in limestone or dolostone.
