摘要
云南北衙地区是一个与喜马拉雅期富碱斑岩活动有关的以金为主的中、低温热液复合式多金属成矿区。北衙红土型金矿属原生矿经风化剥蚀-搬运沉积-富集成矿的表生作用成因类型矿体,是多年来在对与碱性石英正长斑岩共生的金、银、铁、铜、铅、锌等多金属矿藏勘查的基础上,经不断探索而重新认识的大型金矿床。
Beiya area in Yunnan Province is a complex polymetallic metallogenic area of medium and low temperature hydrothermal solution dominated by gold,which is related to the Himalayan alkali rich porphyry activity.Beiya lateritic gold deposit belongs to the supergene genetic type ore body of primary ore after weathering,denudation,transportation,sedimentation and enrichment.It is a large gold deposit that has been re recognized through continuous exploration on the basis of exploration of gold,silver,iron,copper,lead,zinc and other polymetallic deposits coexisting with alkaline quartz syenite porphyry for many years.
