Therion is used in several large projects for the documentation of cave systems. [6] [7] [8] It is listed among 10 of the Best Free Linux Earth Science Software. [9] It was used in a number of scientific projects. [10] Not everyone finds the results satisfying: "Beginning in 2003, the Mulu Caves Project attempted to use Therion on several cave ...
Lechuguilla Cave in New Mexico and nearby Carlsbad Caverns are now believed to be examples of another type of solutional cave. They were formed by H 2 S (hydrogen sulfide) gas rising from below, where reservoirs of petroleum give off sulfurous fumes. This gas mixes with ground water and forms H 2 SO 4 (sulfuric acid). The acid then dissolves ...
For open space filling to take effect, the confining pressure is generally considered to be below 0.5 GPa, or less than 3–5 km (2–3 mi). Veins formed in this way may exhibit a colloform , agate -like habit, of sequential selvages of minerals which radiate out from nucleation points on the vein walls and appear to fill up the available open ...
According to KellerLynn, "Boxwork is a speleogen, forming when bedrock between preexisting calcite veins were preferentially weathered away as the cave developed." [ 1 ] Boxwork is commonly composed of thin blades of the mineral calcite that project from cave walls or ceilings that intersect one another at various angles, forming a box-like or ...
In geology, texture or rock microstructure [1] refers to the relationship between the materials of which a rock is composed. [2] The broadest textural classes are crystalline (in which the components are intergrown and interlocking crystals), fragmental (in which there is an accumulation of fragments by some physical process), aphanitic (in which crystals are not visible to the unaided eye ...
As the acidic water travels through the calcium carbonate bedrock from the surface to the cave ceiling, it dissolves the bedrock via the reaction: CaCO 3 + H 2 CO 3 → Ca 2+ + 2 HCO 3 −. When the solution reaches a cave, the lower pCO 2 in the cave drives the precipitation of CaCO 3 via the reaction: Ca 2+ + 2 HCO 3 − → CaCO 3 + H 2 O + CO 2
Phaneritic rock: Anorthosite from the Stillwater Igneous Complex (Neoarchean; Montana) Igneous textures include the rock textures occurring in igneous rocks.Igneous textures are used by geologists in determining the mode of origin of igneous rocks and are used in rock classification.
A cave pearl is a small, usually spherical, speleothem (cave formation) found in limestone caves. Cave pearls are formed by a concretion of calcium salts that form concentric layers around a nucleus. Exposure to moving water polishes the surface of cave pearls, making them glossy; if exposed to the air, cave pearls can degrade and appear rough.
