Lonsdaleite static press or using explosives. It has also been produced by chemical vapor deposition, and also by the thermal decomposition of a polymer, poly(hydridocarbyne), at atmospheric pressure, under argon atmosphere, at . It is translucent, brownish-yellow, and has an index of refraction of 2.40 to 2.41 and a specific gravity of 3.2 to 3.3. Its hardness is theoretically superior to that of cubic diamond (up to 58% more), according to computational simulations, but natural specimens exhibited somewhat lower hardness through a large range of values (from 7 to 8 on Mohs hardness scale). The cause is speculated as being due
Topaz marsh Topaz marsh Topaz Slough Wildlife Management Area (Topaz Slough WMA) or Topaz Marsh is a marsh system that is part of the old Sevier River bed. The water source stems from springs and irrigation runoff. Topaz Slough WMA is a historical use area for waterfowl and marsh dwelling species. Many different species of birds such as ducks, coots, geese, kestrels, great blue herons, and various shoreline birds can be found during the year. Occasionally, big animals like antelope use water on the west side of the slough. Furbearers include coyote, badger, red fox, and muskrat. Small game species that inhabit
