Pinakiolite.

Warwickite constitutes about 5% of an outcrop of metamorphosed ultramafic rocks of Precambrian age in North-West Greenland. It occurs as slender grains, several millimetres long, and in anhedral grains up to 5 mm in size, together with forsterite, pleonaste, phlogopite, magnetite ± tourmaline.pinakiolite · pinnoïte · préobrajenskite · pricéite · probertite · rhodizite · rivadavite · rowéite · sakhaïte · santite · satimolite · sborgite · sinhalite...As nouns the difference between boron and pinakiolite is that boron is the chemical element (symbol b) with an atomic number of 5; a metalloid while pinakiolite is (mineralogy) a monoclinic-prismatic black mineral containing boron, magnesium, manganese, and oxygen. The molecular structure of pinnoite has been assessed by the combination of Raman and infrared spectroscopy. The Raman spectrum is characterized by an intense band at 900 cm (-1) assigned to the BO stretching vibrational mode. A series of bands in the 1000-1320 cm (-1) spectral range are attributed to BO antisymmetric stretching modes and in ...
