摘要
斑红山地区地层发育,岩浆侵入活动频繁而剧烈,侵入岩分布广泛且规模巨大。区内经历了多次强烈的构造变动,形成复杂的构造形迹,主要以NEE、近EW和近SN向为主。目前,通过地质、物化探及地表探矿工程等手段进行初步查证和追索,在花岗岩与大理岩的外接触带部位发现1处蚀变矽卡岩型金、银和铅多金属矿(化)点,并圈定多金属矿(化)体共6条,认为本区具备寻找接触蚀变岩型+构造蚀变岩型金(银)多金属矿的找矿潜力。
Banbongshan region strata,magma intrusion activity is frequent and violent,intrusive rocks are widely distributed and wity enormors scale,at the same time the region experienced several tectonic movements,formation of comples structural features,mainly in nee,near east-west and South-North to mainly.Through the geological,geophysical and geochemical prospecting and surface exploration engineering means such that the initial check and recourse.Granite and marble in the outer contact zones found an alteration of skarn type Au,Ag,Pb polymetal-lic ore,and delineate 6polymetallic ore bodies,it is believed that this area has prospecting potential to find con-tact alteration rock type and tectonic altered rock type gold-silver polymetallic ore.
