	Helictite - Wikipedia, the free encyclopedia
		Rare "fishtail" helictites in the Caverns of Sonora near Sonora, Texas.
		A helictite is a speleothem found in limestone caves that changes its axis from the vertical at one or more stages during its growth.

		Helictite Cave is located in Virginia and has only one entrance.
		The cave has approximately 6 miles of passage and has a breathtaking display of helictites in the cave.
		The cave is being managed by the owner who is a caver, and he is trying to keep the cave in pristine condition.

	Speleothems: Helictites
		Helictites have a curving or angular form that looks like they had grown in zero gravity.
		Helictites are composed of calcite, dripstone or flowstone.
		If the helictite has a very thin central tube where the water flows like in straws, capillary forces would be able to transport water ignoring gravity.

	Cataloguing Helictites and other capillary-controlled speleothems
		Helictites are a type of speleothem (cave decoration, spelean chemical sedimentary deposit) which are found in the limestone caves of most countries of the world.
		Helictites are further classified into varieties, again based on form (morphology) which can be identified in the field, as seen in Table 1.
		Helictites of a particular form often occur in groups of all one sort, inferring that there is something that has caused the helictites to take on the particular form.

	Helictite
		Forms of helictites have been described in several types: ribbon helictites, saws, rods, butterflies, "hands", curly-fries, and "clumps of worms." Typically the helictite has radial symmetry.
		However, the problem with this theory is that the majority of helictites are definitely not hollow.
		For an unknown reason the chemical composition of the water is slightly altered causing the single crystal structure to change from a cylindrical shape to a conical one.

	Timpanogos Cave National Monument, Utah
		These exquisitely beautiful caverns are decorated with a dazzling display of helictites and anthodites in a variety of fantastic shapes.
		Helictite, a strange and exotic sounding word, is the name of a strange type of cave formation found in these caves.
		Smooth but spiraling helictites are made of calcite; needle-like crystals are made of aragonite, a mineral chemically identical to calcite but with a different crystal structure.

	Geohiking Trail Description
		Its landmark status was granted primarily due to its substantial colony of rare helictite crystals.
		Helictites are formed under unusual conditions, which include water under pressure and the presence of certain trace minerals.
		Since helictites must battle gravity, they do not usually grow much larger than a few inches, but at Black Chasm Cavern there are many long helictites, including one near the entrance to the cave that measures twelve inches long.

		Timpanogos cave is particularly will known for it's abundance of helictites which are relatively rare in most other caves.
		Helictites are formed by capillary action, which pulls pressurized water through tiny holes or pores on the surface of wall coatings or other formations.
		Some geologists have suggested that it is the wedge shape of the calcite crystals that cause the helictites to twist and turn erratically.

	KIDSPAGE Formations: Helictites (Site not responding. Last check: 2007-10-13)
		Helictites are formed in caves when water under pressure is pushed through a limestone wall, depositing calcite on the other side.
		Helictites are found in the walls and ceilings of caves and also can be found growing off stalactites and soda straws.
		Good displays are rare, but there are many excellent helictites in the ceiling of the Jungle Room at California Cavern, and Black Chasm Cave was named a National Natural Landmark in 1976 for its spectacular displays (pictured left) of these fascinating formations.

		In the case of Helictite Cave sluggish phreatic, dynamic phreatic and vadose action may have operated simultaneously in different parts of the same cave.
		Helictite and Shaft Caves formed when the valley had been cut down to within 30m of its present level and some early phreatic development also took place in the Belfry Cave at this time.
		Helictites are related to porous wall surfaces, spar crystals result from flooding of caves in the vadose zone and blue stalactites are composed of aragonite.

		SEM photographs of surface of a ribbon helictite show an unusual crystal form for a calcite speleothem, together with apparent etching and pitting of surfaces.
		Further optical work revealed that stem of ribbon helictites is composed of a twinned pair of crystal aggregates, with stem's central canal lying in this twin plane.
		It is proposed that ribbon helictites form by two growth stages: development of stem and then a ribbon, with influences from acidic solutions.

		If the roof of the cave is of a gentle enough slope a drop of water may run down the wall rather than falling directly onto the floor to form a stalagmite.
		Helictites form when the water which feeds them is exuded from the rock sufficiently slow that it does not form a drop of water.

		Helictite sind Speleotheme, welche ihre - eigentlich physikalisch bedingte vertikale Achse während verschiedener Wachstumsphasen ändern und - als ob es keine Schwerkraft gäbe, in alle Richtungen weiterwachsen.
		Die Kapillarkraft-Theorie basiert darauf, daß Helictite einen zentralen Kanal haben, durch welchen das Wasser wie in einem Strohhalm fließt.
		Diese Theorie wurde davon inspiriert, daß einige Helictite hohl sind - Tatsache jedoch ist, daß die meisten Helictite nicht hohl sind.

	Speleothems
		While small helictites are found in many caves, the helictite bushes are large, bush-like growths of calcite that branch and twist like gnarled trees.
		The helictite bushes usually grow from the floor of the cave.
		The helictites may form when water seeps into the cave through pores so small that the flow is controlled by capillary action and not by gravity.

	Granite Bay View - Treasures abound underground (Daytripper)
		For adventure seekers and casual tourists alike, Northern California is home to a half dozen caverns that boast everything from rare helictite crystal formations and rappelling to gemstone mining and easy-to-handle walking tours.
		Unlike the stalactites and stalagmites traditionally found in caves and caverns, helictite formations are created when water forces its way sideways through rocks underground.
		The results are white formations that resemble collections of antlers jutting out in all directions from the walls of the cave.

	Cave Formations
		The most common are stalagmites, which are columns that form from the bottom up and stalactites, which build from the top down.

		Helictites are also a very interesting cave formation.

		Several lines of evidence suggest that the "helictite bushes" of Wind Cave grew underwater, probably where localized plumes of thermal water once welled up into ambient groundwater then standing in the cave.
		In their physics of origin, helictite bushes may be more closely related to features like submarine "smoker chimneys" than to normal helictites.
		The chemistry of helictite-bush growth has not been investigated, but may involve calcite crystallization by the "common ion effect" where calcite-rich and gypsum-rich waters interact.
