热水沉积-热液改造成因铅锌矿床——河南熊耳群火山岩中一种新的矿床类型

Hydrothermally modified sedex Pb-Zn deposit--A new deposit type in volcanic rocks of the Xiong''''er Group, Henan, China

摘要: 骑马沟铅锌矿赋存于熊耳群条纹状硅质大理岩与火山凝灰岩之间。通过对矿床地质、岩石、矿物组合特征等方面的初步研究，认为该矿床为热水沉积一热液改造成因铅锌矿床，其成矿主要与熊耳期火山岩及火山气液作用有关。这是在河南熊耳群火山岩中首次发现的该类矿床类型。

Abstract: The Qimagou Pb-Zn deposit occurs between onyx siliceous marble and volcanic tuff of the Xiong'er Group. Study of the geology, rock association and mineral assemblage of the deposit indicates that it is a Pb-Zn deposit of hydrothermally modified sedex origin and that its mineralization is mainly related to the Xiong'erain volcanic rocks and volcanic exhalation. This is the first ore deposit of such type found in volcanic rocks of the Xiong'er Group in Henan.
