中文摘要:提要:控矿构造一直是热液矿床研究的难点之一,本文以大兴安岭中段为研究对象,通过1∶25万柴河镇幅和蘑菇气幅地质调查,提出:(1)该区主干控矿构造由大黑山—太平岭—鸡冠山北断裂带和扎兰屯市—哈多河断裂带构成,形成时代主要为海西期和燕山期。(2)控矿构造性质主要表现为压性、张性和剪切性质,三者之间分别经历了剪切与拉张,剪切与压扭性质之间的转换,主压应力场依次发生E-W向、SE-NW向、SSE-NNW向三次变化。(3)总结出该区主干构造控矿、分枝构造控矿、平行构造控矿和斜列构造控矿等若干赋矿规律,该赋矿规律与该区导矿构造,导矿构造和矿源与深部板块俯冲产生熔融岩浆密切相关。这些新认识为该区的地质基础、成矿理论深入研究和找矿工作等均具有重要的意义。

The ore-control structural features and ore-host regularity of Chaihe-Moguqi area in the Da Hinggan Mountains
Abstract:Abstract:Ore-controlling structure is always one of the difficulties in the study of hydrothermal deposits. With Chaihezhen-Moguqi region of the Da Hinggan Mountains as the study object, this paper puts forward some conclusions on the basis of the 1:250000 geological investigation of. Chaihezhen-Moguqi region. 1. The main ore-controlling structures are Daheishan-Taipingling-Jiguanshan fracture zone and Zalantun City-Haduo River fracture zone, and the formation ages are mainly Hercynian and Yanshanian. 2. Ore-controlling structures mainly show compression, tensile and shear properties, and between the three properties, there existed the conversion between shear and tensile and between shear and torsion, with the principal compressive stress field changing in the directions of E-W, SE-NW to SSE-NNW in succession. 3. The regularities of the main ore-controlling structures, the branching ore-control structures, and the parallel and inclined ore-controlling structures are summarized in this paper. These regularities, the structures as passageways for ore fluids and the ore source were closely related to deep subduction which produced molten magma. These new ideas are of great significance for the detailed study of geological foundation, metallogenic theory and prospecting work in this region.
