Fellinibright
Granite
Structure: A white-grey Gneis is FELLINIBRIGHT. The principal part in the rock forms the white feldspar. Quartz arises light-grey. Black biotite (dark mica) form restrained, black-grey, blurred to cloudy ornamentations. The characteristic of FELLINIBRIGHT is a lighter pink glow, which resulted from storages of hematite (ferric oxide) into the feldspar. Because of the changing texture FELLINIBRIGHT sampling is quite difficult. In order to obtain a general impression of the rock, prototype sample are not sufficient usually. A wide sampling to the switching of an impression and the effect of the rock is recommended.
Characteristics: FELLINIBRIGHT possesses after the MOHS hardness scale (1 = chalk, 10 = diamond) a degree of hardness of 6-7; it ranks among the hard rocks and is to a large extent frost steady
Emergence: FELLINIBRIGHT belongs as Gneis to the family of the metamorphic rocks. All rocks of this group developed under partly very high pressures and temperatures, which stopped longer time and which more or less strongly materially and structurally changed origin rock. From quartz and feldspar developed for partial remelt opens of a sandigen output rock as well as from a small portion of clay/tone slate sediments the mica minerals. With a on one side arranged pressure developed a Paralelltextur, which in a lie-wise arrangement mica expresses itself.
Age: Approx. 1.4 billion years (Precambrian).
