摘要:

水晶屯金矿床位于张宣幔枝构造轴部, 水泉沟—大南山碱性角闪二长岩杂岩体的西缘。金矿化分布于尚义—赤城韧脆
性剪切带中段。含金矿物主要为自然金和银金矿, 赋存于石英、黄铁矿、方铅矿裂隙和胶结物颗粒间, 矿石构造为细脉状、浸染状和团块状, 围岩蚀变为硅化、黄铁矿化、绢云母化等。通过对本矿区的元素相关系数、硫、铅、氢、氧同位素特征等的研究分析, 认为水晶屯金矿成矿物质主要是来源于深部的核幔物质, 受构造控制明显。

Abstract:

Shuijingtun gold deposit is located in the central axis of the Zhangjiakou-Xuanhua mantle branch and in the west of alkaline hornblende monzonite in the area of Shuiquangou-Dananshan in Zhangjiakou. Gold mineralization appears in the middle of ductile shear zone in Shangyi-Chicheng. Gold-bearing minerals are mainly the natural gold and electrum,which are attached to clay minerals or with in crevices of quartz,pyrite and galena as w ell as in between grains of cements,disseminating as vein let or in disseminated and granular shape.Wall rock alteration are the silici-fied,pyritized and sericitized.This paper holds that the metallogenic material of Shuijingtun gold deposit are mainly from core-mantle in depth,based on the research of the elements correlation coefficient as well as the characteristics of some isotopes,such as sulfur,lead,hydrogen and oxygen,etc.

Key words: Mantle-branch structure, Material source, Mineralization, Ore-controlling structures, Shuijingtun gold deposit, Zhangjiakou-Xuanhua region
