Mineral Analysis
A chemical analysis of a mineral is expressed as a table of weight percent (wt.%) of its component elements or oxides. Concentrations lower than about 0.5 wt.% are often expressed as parts per million (ppm) by weight of element.These mineral analyses are easily converted into atomic formulas and thence into percentages of the end-member 'molecules' within the mineral group …
