Type Localities of Utah

Type locality is a term used to denote where a mineral was first discovered. Sometimes a mineral may be discovered at one site, but not enough material is available to do the proper analysis to describe it as a new mineral. When this happens, that mineral has to wait until it is discovered somewhere else where there is enough material to be described. When this happens, both places are listed as co-type localities.   See Mcalpineite.

Listed here are minerals first discovered in Utah.

Mineral Descriptions:

AbelsoniteNiC31H32N4

 Description: Abelsonite is a crystalline nickel porphyrin mineral. It is a mineral derived from organic materials. It was found in eight cores drilled from or near the Mahogany Zone oil shale of the Green River Formation of Unitah County. It occurs as platy crystal aggregates ranging from 30 microns to 3mm in long. It was also found lining a tight vertical fracture, and was coated with an unknown black substance. Color ranges from pink-purple to dark red-brown, with a submatallic to adamantine luster. It’s hardness is less than 3. It is not fluorescent under long or short wave ultraviolet light. It is insoluble in water, hydrochloric acid, nitric acid, and in benzene and acetone.

Crystallography: Triclinic. Space Group: P-lattice. Forms in platy aggregates. {111}. (line over middle one)

Location: Abelsonite was first discovered in a core sample from the WOSCO well for the Western Oil Corporation. The well is located in quadrangle Big Pack Mt. NE. Sec 36 T 9 R 20 E. It came from the 2508.2 foot level of the well. This sample came from the Mahogany Formation. This is a subsurface analog of the kerogen-rich Mahogany Ledge of the Parachute Creek member of the Green River Formation. Once abelsonite was recognized at this location it was not hard to find it at other locations. It was found at five different wells, all within the core samples. The other wells are in a cluster about 16 miles south of the WOSCO well, but all still within or near the Mahogany Formation.

Named for and Discovered By: Abelsonite was discovered by Lawrence C. Trudell, from the Department of Energy/Laramie Research Center in 1969. It was named in honor of Philip H. Abelson, President, Carnegie Institution of Washington.

Associated Minerals: Abelsonite was found associated with orthoclase, pyrite, quartz, dolomite, analcime and an unknown K-Fe micaceous mineral.

Other Locations: This is the only known occurrence of this mineral.

Location: The classic location was first reported as 35 miles southwest of Simpson Springs at the southern end of the Dugway Mountains. It was later found to be in the Thomas Range. The original location error happened because it use to be thought that the Thomas Range and the Dugway Mountains were the same range. The original location (Maynard Topaz Mine) is currently being mined for Bixbyite and topaz. Bixbyite is now found at several locations in the Thomas Range.

Named For and Discovered By: Bixbyite is was discovered in the late 1890’s. It was discovered by and named for Maynard Bixby. Maynard Bixby was a pioneer in the exploration of the Thomas Range.

Braitschite-Ce7(CaNa2)O-RE2O3-11B2O3-7H2O

Description: Braitschite occurs in nodules within anhydrite rock. The nodules occur between 6 inches and 3 feet from the basal part of the anhydrite bed. The anhydrite bed is overlying a sylvite-rich salt bed. The nodules occur roughly spherical. The smaller are more spherical. They range in size from 0.05 to 8 mm. Compound nodules of up to four grouped together are were noted. The nodules were pink to red due to hematite staining. Braitschite occurs in the nodules as clear to white hexagonal plates. Specific gravity is 2.9. There is question concerning how these nodules formed. There are no other rare-earth borate minerals known. There are no other rare-earth marine evaporate deposits known. This makes the study of this deposit unique. There are a few theories to the mode of deposition, however. The most accepted one is that the nodules formed as a result of a diagenetic process.

Crystallography: Trigonal. Braitschite forms within nodules as clear to white hexagonal plates. The hexagonal plates showed only the pinacoid and prism forms. The plates range from 0.1 to 70 microns in diameter. All the crystals observed were euhedral. The differences in the shape were due to different degrees of developement. The general outline observed on the pinacoid, was hexagonal to triangular. Some of the crystals showed a "lozenge" shape.

Location: Braitschite was found in core samples from 3,000 to 3,500 feet deep from the Cane Creek Potash Mine. The mine belonged to The Texas Gulf Sulfur Company, and was located about eight miles southwest of Moab (SE 1/4 sec 24, T26S, R20E), Grand County. The core samples were out of the Paradox Member, Hermosa Formation, and is Pennsylvanian in age.

Named For and Discovered By: Braitschite was named in honor of Professor Dr. Otto Braitsch of the University on Freiburg, Germany.

Associated Mineral: Braitschite is found in nodules of anhydrite. Pyrite, chalcopyrite, quartz, dolomite, anhydrite, halite, and small amounts of hematite are also found associated with Braitschite.

CoconinoiteFe2Al2(UO2)2(PO4)4(SO4(OH)2-20H2O

Description; Coconinoite forms light creamy lath-like aggregates and at one location in platy grains on sandstone. It is non-fluorescent under both longwave and shortwave. Coconinoite is soft and has a specific gravity of 2.7. It occurs in an oxidized zone of a sandstone uranium deposit. Coconinoite was discovered at other locations in Arizona, both are given credit as type locality. Utah is then a Cobalt-zippeite "type locality".

Crystallography: Orthorhombic. Coconinoite is to fine-grained for single crystal studies, however it is believed it may be monoclinic. This is suggested and supported by the extinction lines from x-ray diffraction studies.

Location: It was first discovered at the Jomac Mine, White Canyon, San Juan County.

Named For & Discovered By: Coconinoite is named for Coconino County, Arizona, where it was also discovered at the Sun Valley and Huskon Mines. It was discovered by A.F. Trites, Jr. of the U.S. Geological Survey, in 1953 when he conducted a study of the Uranium deposits in the White Canyon area of southern Utah.

Associated Minerals: Coconinoite was often found covered with gypsum. It is also associated with jarosite, limonite, petrified wood and coalized wood, clays and with uranium ores. It was found on quartz sandstone.

Other Localities: Coconinoite has been found in several mines in Arizona including the Blackwater No.4 Mine, Sun Valley Mine, and the Huskon Mine, all in Coconino County. All the locations have the same type of geological environment, a sandstone uranium type deposit.

CorvusiteV2O4-6V2O5-X H2O

Description: Corvusite has a purplish blue-black to brown color. Luster is blue-black. It is massive, but studies of the slickensides suggests that is maybe fibrous. Hardness is 2.5 to 3. Fracture is concoidal. Specific gravity is 2.83 (determined by heavy solution). Streak is the same color as the specimen, the color difference is the blue-black to brown is due to a higher iron content in the brown specimens. Corvusite is soluble in mineral acids. Corvusite is one of the more common black minerals in the carnotite deposits of this area, yet very little was suitable for research.
