Abstract
Small streams fed by subsurface run-off, subject to ore-oxidation activity, alter in chemical composition and are thus useful in hydrochemical prospecting for ores. Surface-flow types most favorable to hydrochemical prospecting are identified; and, the optimum time of the year established for positive identification of oxidizing-ore occurrences by surface-water chemical composition. The author chose the Lory plateau in Northern Armenia as the area of investigation. The topography of the area is mountainous; elevations above sea-level range from 1100 to 2700-2800 meters. Its climate is temperate alpine, and the annual precipitation of 650 to 750 millimeters is heaviest during the period from April to June. Sedimentary and effusive tuffs, of Middle Jurassic to middle Eocene age, contain numerous polymetallic, chalcopyrite, copper-arsenic, pyrite, and other ores; minerals are principally sulfides. A high-intensity water cycle resulting in abundance of springs and surface flows is characteristic of the region...
