大井锡多金属矿床矿化中心的探讨

STUDY ON THE MINERALIZATION CENTER OF DAJING TIN-POLYMETALLIC DEPOSIT, INNER MONGOLIA

讨论一个大井矿床、矿体、矿物及元素的空间分带性 ,结合对成矿流体物理化学条件空间变化的研究 ,推断了大井矿区矿化中心。认为矿区主要的矿化中心有两个 ,一为矿区中部 ,即老区东部—北区南部一带 ;另一个矿化中心在矿区的西部。这两个矿化中心分别位于北东向的F2 和F1断裂附近 ,表明这两条北东向断裂是矿区的导矿构造。

Based on the discussion on ore bodies, ore minerals and major elements, combined with metallogenic spatial variation of metallogenic physical-chemical condition, this paper has inferred the mineralization center of Dajing mining district. It is considered that there exist two major mineralization centers which are located in middle part (i.e., around eastern Laoqv block to southern North block) and western part of mining area respectively. Those two mineralizing centers just approach NE trending faults of F 2 and F 1, which reasonably evinces that those faults could be regarded as the channel-way for ore-fluid of this area.
