A SIMPLE METHOD TO SEPARATE QUARTZ - Geochronometria- dissolution of quartz in mieral processing ,be assigned to quartz or feldspars because those minerals differ in temperatures at which emission acid etching aims at preferentially dissolving feldspars, even if some quartz is lost in the process, and also to remove the mineral outer layerWEATHERINGWeathering is a term which describes the general process by which rocks are tend to weather much faster than felsic minerals like quartz and feldspar Different minerals show different degrees of solubility in water in that some minerals
