摘要
Bafangshan-Erlihe large lead and zinc ore deposit has metallogenic characteristics of hydrothermal sediment and paulopost reforming, but the distribution of REE, B, Ba, Tl and other elements has not wholly clear submarine exhalative feature, that also indicates the deposit has a far distance to exhalative center. The formation of Bafangshan-Erlihe large lead and zinc ore deposit went through hydrothermal sediment and structure reformation two stages, metal elements initially enriched in Middle Devonian stratum in sedimentary stage, which provided substances source for later structure reformation. It concludes the ore deposit genesis belongs to basement hydrothermal exhalative sedimentary-tectonic magma reformation type. The main ore-controlled structure included synsedimentary anticline, syngenetic fault that was hydrothermal transportation pathway and local sedimentary basin where ore-forming substances sedimented and enriched in this lead-zinc ore region.
