Characteristics of sandstone copper ores in Tianlu copper deposit
摘要
Abstract
The Tianlu copper deposit formed in Paleozoic foreland basin is a marine sandshale copper deposit, whose copper ores are mainly of the siltstone type and comprise six kinds of ore species, namely chalcocite ore, chal-cocite-bornite ore, bornite ore, chalcopyrite-bornite ore, chalcopyrite ore and pyrite-chalcopynite ore. Ore textures are mainly composed of crystallization texture and metasomatic texture. Ore structures are dominated by disseminations. Along the thickness of strata, mineralization of the major ore bed assumes obvious vertical zonal-ity in the upward order of bornite→chalcocite→chalcopyrite→pyrite, indicating a typical sulfide arrangement and association of sedimentary copper ores. These characteristics are consistent with features of marine sandshale copper deposits both in China and abroad.关键词
