The study on massive hydrogrossular by means of polar microscope, infrared spectra and Xray shows that it consists mainly of hydrogrossular, with a little amount of diopside and calcite.
In this paper, estimating law for mineral content, simple proof of the law and determining lowest sample size and error range in measure and statistics are discussed.
