Annotation:

The research paper presents the characteristic of quartz of various generations contained in the Alpine-type quartz veins of the Lower- and Middle Jurassic schistose terrigenous formation of the fold system of the Greater Caucasus. Within the Alpine-type quartz veins there has been distinguished quartz of three main generations: milky quartz belongs to the first generation; the second ge-neration is represented by elongated, often parallel quartz crystalline aggregates and the third generation - by quartz druse. The Alpine-type quartz veins are commonly formed under the low temperature conditions and genetically they are related with metagenesis of the rocks of terrigenous formation. Mostly, quartz veins are sterile from the useful components. Majority of the quartz aggregates contain gas-liquid inclusions of various forms and sizes that are the peculiarity of the quartz veins and defiine the conditions of metamorphism.
