| Summary: | With the use of the methods of the inductively coupled plasma mass-spectrometry (ICP-MS) and infrared spectroscopy, the concentrations of Al, Ti, Li, Ge, B and rare earth elements, and the impurity centers containing group ОН? have been studied in the quartz of veins with tungsten, gold-rare metal and silver mineralization. With simiiar contents of Al and Ge, the quartz of veins with tungsten mineralization differs from the quartz of gold-rare metal veins by lower concentrations of Ti and higher contents of Li and B. In the early white quartz near salband of the veins with tungsten mineralization concentration [AlO4/LiH]0 the amount of impurity ceniers is higher than in a later smoky quartz. Rare earth elements spectra of quartz in veins with tungsten mineralization are different from those of the spectra of the quartz of gold-rare metal veins by the presence of the tetrad effect of the M-type, especially by a clear convex tetrad Gd-Tb-Dy-Ho. The quartz of the low-temperature veins with the silver mineralization has a bimodal distribution of Al concentrations - a very high content in early comb quartz and low - in the late coarse-grained quartz; distribution of Li and Ge concentrations is simiiar. |
