Morphostructures of Pamir: historical-genetic analysis as applied to metallogeny prospects

Abstract

Three categories of morphostructures are distinguished: 1) orogenic systems of arcuate ridges concordant with main tectonic zones which came into being in consecutive order during the Late Paleozoic, Mesozoic and Cenozoic as the geosynclines closed, 2) discordant to the first ones, large annular morphostructures, wick resulted from huge igneous (mostly granitic) mass intrusion into upper lithosphere during tectonic and magmatic activisation stages in Early Mesozoic, Late Mesozoic and Tertiary, 3) through linear zones of mostly latitudinal and longitudinal trends, accompanied with large disturbances and morphostructural anomalies, of prolonged development. High order annular morphostructures control the position of rare-metal ores, the latters preservation depending on how deeply they have been eroded, A series of most promising annular morphostructures is selected within the limits of the East Pamir.
