金厂峪金矿位于河北省唐山市迁西县，是我国大型金矿之一。本文以野外地
质调查为基础，应用构造地质学、大地构造学、矿物学、岩石学、矿床学、地球
化学等学科理论方法，对矿区及矿床地质构造特征的基本特点、矿床类型、成矿
有利部位等方面进行综合研究分析。
本文在前人研究的基础上，从区域地质特征入手，对本区的区域构造格局、
变质岩岩石学基本特征、金矿矿源层、矿区构造的基本特征、矿石类型与成分结
构、矿石矿化类型、围岩蚀变类型、矿脉的产出形态以及控矿构造特征等方面进
行综合分析，明确了挤压片理化带的控矿意义，对矿床成因提出了初步的认识，
并初步建立本矿床成矿模式。
通过以上的研究，主要取得了以下几点认识：1）金矿的基底为主要由迁西
岩群及遵化岩群组成太古界变质地层，沉积盖层主要由中-晚元古界的长城群、
蓟县群和青白口群组成。2）整个矿区被北北东向压紧同斜的挤压片理化带贯穿。
太古宙的基性片麻岩为矿源层之一，燕山期热液活动，青山口岩体侵入，使金元
素进一步富集。3）金厂峪金矿矿脉产出受构造、岩石类型、围岩蚀变的控制，
这些都成为找矿的直接标志。4）未来的有利成矿部位主要在挤压剪切片理化带
的深部、四级紧闭背斜转折端部位以及西部铁矿体之下。5）金厂峪金矿为岩浆
期后中温热液石英脉型矿床。6）金厂峪金矿为多期成矿，矿源层主要为斜长角
闪岩与青山口花岗岩。

Abstract
Jinchangyu gold deposits is located in Qianxi district, Tangshan city, Hebei
province, it is among China's large scale gold deposits. Upon field investigation, we
made comprehensive and synthesis analyses of the basic characteristics, deposit types,
favorable position of mining area of the deposits using tectonic geology, tectonics,
mineralogy, petrology, mineral deposit geology, geochemistry and other theoretical
method.
Based on previous studies, and starting from regional geology, the area's tectonic
structure, basic characteristics of metamorphic petrology, gold deposits source layer,
structure of the basic features of mining, ore types and the composition, type of ore
mineralization , wall rock alteration type, the output and shape characteristics of veins
and ore-controlling tectonic characteristics are analyzed comprehensively, the
ore-controlling significance of schistosity band squeeze is cleared, preliminary
understanding of deposits originality is given, and mineralization mode is established
elementarily.
Through the above study, following understanding is established:
1) Substrate of the deposits is Archean metamorphic stratigraphy, and it is
composed of Qianxi rock group and rock group Zunhua, sedimentary cover is mainly
