Abelsonite is a mineral of nickel, carbon, hydrogen, and nitrogen with formula: Ni[C₃₂H₃₆N₄]. It forms purple to reddish brown triclinic crystals. The crystals are soft, with a Mohs scale rating is 2 to 3. It has a low specific gravity of 1.45. Minerals are natural compounds formed through geological processes. ... A chemical formula (also called molecular formula) is a concise way of expressing information about the atoms that constitute a particular chemical compound. ... In mineralogy, shape and size give rise to descriptive terms applied to the typical appearance, or habit of crystals. ... In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. ... Cleavage, in mineralogy, is the tendency of crystalline materials to split along definite planes, creating smooth surfaces, of which there are several named types: Basal cleavage: cleavage parallel to the base of a crystal, or to the plane of the lateral axes. ... For fractures in geologic formations, see Rock fracture. ... Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer. ... Lustre (American English: luster) is a description of the way light interacts with the surface of a crystal, rock or mineral. ... Minerals are natural compounds formed through geological processes. ... In physics, Density is defined as mass m per unit volume V. Mathematically, it is expressed as where, in SI units: ρ (rho) is the density of the substance, measured in kg m-3 m is the mass of the substance, measured in kg v is the volume of the substance...

Relative density (also known as specific gravity) is a measure of the density of a material. ...

It was first described in 1975 for specimens in oil shale from the Green River Formation, eastern Uintah County, Utah. It is named after Philip Hauge Abelson, an American physicist. Oil shale is a general term applied to a group of rocks rich enough in organic material (called kerogen) to yield petroleum upon distillation. ... The Green River Formation is an Eocene geologic formation that records the sedimentation in a series of intermontane lakes. ... Uintah County is a county located in the U.S. state of Utah. ... Philip Hauge Abelson (April 27, 1913 - August 1, 2004) was a physicist, editor of scientific literature, and science writer. ... ...
