The term "cave" refers to a natural opening, usually in rocks, that is large enough for human entry (Gunn, 2004). There are several different types of caves: volcanic, glacier, crevice, erosion, and solution. Solution caves occur in limestone and gypsum and are the most common type in central Texas.
Igneous Rock Igneous rocks are formed by magma and lava as it cools. Igneous rocks form in two different ways. Rock that comes from lava cools very fast and can either be very light and airy or the rocks can be glassy.
Most caves are formed in limestone areas. Limestone is unique because its mineral grains can be dissolved in nature by a very mild carbonic acid. The weak acid forms from a mixture of water from rain and carbon dioxide from air and the soil.
Physical factor • Thickness of Limestone is important in formation of the karst. Massive limestone can stand to dissolution process and display a karst beautiful karst features. • Sometimes, the limestone also may interbed with another type of rock such as mudstone. This type of karst generated from this may be differ from pure limestone ...

hydrochemistry. In February 1990, the Cave Springs ground-water basin near Hixson, Tennessee, was selected for one of these areal studies. Cave Springs, a dominant feature of the Cave Springs ground-water basin, is one of the most productive spring systems in Tennessee and is a single spring used by the Hixson Utility District to supply
Rich deposits of bauxite, limestone, dolomite and corundum are also found in the state, making it the ideal location for low-cost of production of end-products such as cement and aluminium. During 2011-12 (upto December 2011), the state had generated a revenue of US$ 412.2 million from minerals.

Caves. A cave is a naturally occurring underground hollow or passage, especially one with an opening to the surface of the Earth. Caves often form in limestone areas when underground water dissolves the rock, forming tunnels passages and even large caverns. There are several caves in Barbados, the most famous of which is Harrison's cave.

Formations grow slowly, but as long as water is moving through the cave they will get bigger and bigger. Stalactites and stalagmites grow together to make columns. Eventually the entire cave may fill up with calcite. Or the outside rock may erode away to expose the cave.
