Research Progress of Gold Deposits of Ductile Shear Zone——Taking Ailaoshan Gold Zone as an Example

  • Online:2011-02-28 Published:2012-03-16

摘要:

韧性剪切带型金矿因其独特的地质特征而成为广大地质学家关注的焦点,而哀牢山金矿带中的金矿床是典型的剪切带型金矿,内有十几个大、中型金矿。区域构造上,这些金矿床皆位于哀牢山断裂带中的哀牢山浅变质带内,各个矿床均受次一级断裂系统的控制,但从具体控矿条件上看,各个金矿各有其成因特点,属于不同的成因类型。对这些矿床的研究,目前还不太成熟,特别是对整个哀牢山金矿带的成矿规律和成矿机制还需要进一步的研究。

Abstract:

Ductile shear zone gold deposits become the focus of attention of geologists because of its unique geological features.Ailaoshan is the most important ductile shear zone,which consists of more than ten medium to large sized gold deposits.In terms of regional structure,these gold deposits are located in the epimetamorphic belt in the fault zone of Ailaoshan.All deposits are subject to second-level fault system,but regarding of the specific conditions of ore-controlling,the individual gold deposit which has its own characteristics formed differently.Studies of these deposits are still developing.Further study is needed,especially for the gold metallogenic law and metallogenic mechanism of the gold deposits belt in Ailaoshan as a whole.

Key words: Ductile shear zone, Ailaoshan gold belt, Metallogenic mechanism
