    THE STRUCTURAL STRUCTURAL CHARACTERISTICS AND ITS GEOLOGIC SIGNIFICANCE OF THE TANJIANSHAN GOLDFIELD

    • 摘要: 本文首次研究了滩间山金矿田的构造特征。万洞沟群沉积时已有北东向同生断裂;元古宙末,万洞沟群褶皱;矿田内发育北东、北西两个方向的韧性剪切带和脆性断裂。因此,万洞沟群并非单斜;本区金矿的形成富集与构造演化密切相关,为黑色岩系中同构造多因复成矿床——滩间山型金矿床;同生断裂与不同方向韧脆性剪切带叠加部位和闪长玢岩及煌斑岩脉经韧脆性剪切作用改造之处是金的成矿有利地段。

       

      Abstract: Structural characteristics of the Tanjianshan goldfield are first studied in this paper.There are simultaneity faults in NE when the Wandonggou group is sedimented.The Wandonggou group is folded during the late Proterozoic era. Ductile shear zones with brittle faults in NE and in NW can be found in the goldfield;Therefore, the wandonggou group is not monocline, The formation and abundance of gold ore is closely related with tectonic evolution in this area. This kind of deposit can be named the syntectonic multiple genetic gold deposit in the black rock formation or Tanjianshan-type gold deposit.Minerogenic favourable places for prospecting are situated at where the simultaneity faults are superim-posed ductile-brittle shear zones in different diretction or the diorite porphyrite and lampro-phyre dikes are sheared whte they are ductile-britlle.
