They don't!
Deposits don't form caves, but limestone is a sedimentary rock formed from marine or lacustrine deposits.
Caves form within limestone by dissolution of its calcium carbonate by ground-water flowing through the rock's joints, bedding-planes and faults.
Caves usually and mostly forms in sedimentary rocks. Example, Limestone.
Caves are formed by rainwater dissolving away limestone or sandstone.
Limestone is a type of rock that is easily eroded by water, which can create caves over time. Water dissolves the limestone rock to form caves through a process known as chemical weathering. Additionally, limestone can also be carved out by underground rivers or other natural forces, resulting in the formation of caves.
I think I know what you mean.The vast majority of the world's caves are formed in limestone by water dissolving the calcium carbonate that is the rock's main constituent. As for "type", well, almost any "type" by age or source of limestone physically capable of supporting itself above the developing void. Caves will also form in marble (metamorphosed limestone) and in gypsum (calcium sulphate), in the same way.So the limestone is not "often found in caves" - except as boulders that fallen from the roof, or re-precipitated as calcite stalactites etc - but is literally all around almost all caves!More to the point perhaps is the combination of factors that encourage or discourage caves to form in a given limestone area, and that is far more complex.
Limestone.
Karst caves (i.e. dissolutional features in limestone).
Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.
For most caves, in limestone, sufficient precipitation over sufficiently long time - but cave development also depends the region's geology and geomorphology.
Limestone is formed on the floor of ancient seas from the skeletal remains of marine organisms such as coral, forams and molluscs, etc.

Limestone. The caves are located in a limestone mountain range called the Guadalupe Mountains.
