摘要:

梨园金矿隶属太行山北段多金属成矿带,是山西省灵丘地区发现的一处中型金矿床,矿区内已发现的金矿体均赋存于NNE向断裂带中。本研究共采集677件岩石样品进行微量元素分析测试,利用迭代法计算各元素异常下限。通过相关性分析、R型聚类分析和斜交因子分析,研究各元素之间的相关关系,分析矿床成矿地质地球化学环境,厘定矿床成矿元素为Au,成矿直接指示元素组合为Cu-Pb-Zn-Ag,间接指示元素组合为As-Sb-Hg。Au元素异常主要分布在发育强烈褐铁矿化的花岗岩体、岩脉和地层中,展布方向为NE-SW向,与区域构造线方向相吻合,矿化受岩体及破碎带控制明显;指示元素异常组合分布范围与成矿元素叠合程度高,对金成矿指示作用明显。综上得到梨园金矿的构造地球化学特征,以用于本区的成矿预测,对于丰富和完善该区金矿地球化学模型有一定的指示意义。

Abstract:

Liyuan gold deposit,a medium-sized gold deposit discovered in Lingqiu district,Shanxi Province,is located at the polymetallic metallogenic belt in the northern section of Taihang Mountain.The outcrop strata in the mining area is the Neo-Archean Fuping Group,which mainly consists of migmatite,gneiss and amphibolites.Faults are well developed and can be divided into four groups of NNE,NE,NW and near EW-trending among which the NNE-trending fault is the main ore-controlling structure.The orebodies mainly occur in the NNE-trending fault zone.In this study,a total of 677 tectonic geochemical samples were collected,and the contents of thirteen trace elements (Cu,Pb,Ni,Mn,Ag,Zn,Co,B,As,Sb,Bi,Hg,Au) were analyzed.The lower limit of each element anomaly is calculated by iterative method.Through correlation analysis,R cluster analysis and oblique factor analysis,the correlation of each element was studied,and the geological and geochemical environment of the Liyuan gold deposit was analyzed.The research result shows that the metallogenic element Au has a good correlation with Bi element,and bismuth minerals play an indicative role in mineralization.However,the correlation between Au and other elements is weak,shows the relative independence of gold during mineralization.Based on the above analysis,abnormal combinations of multiple geochemical elements are complete in the deposit,and can be classified as follows:Metallogenic element is Au,direct indicator elements are Cu-Pb-Zn-Ag,and indirect indicator elements are As-Sb-Hg.The denudation degree of the deposit is low.Spatial distribution of abnormal combinations shows that ore-forming element (Au) anomalies are mainly distributed in granite,diabase dike and strata with intense limonization.The distribution direction is NE-SW-trending,consistent with the regional tectonic line,and the gold mineralization is obviously controlled by the rock mass and the broken zone.The distribution range of abnormal assemblage of direct indicating elements overlap with that of metallogenic element,Au,Ag,Cu,Pb,Zn are the near-ore hole association,whose strong anomaly plays an important role in indicating gold mineralization.Also,this combination has great significance for concealed orebody.Indirect indicator element combination anomaly is mainly located in the distribution area of granite and diabase vein,indicating that the metallogenic rock body and the ore-forming process are rich of Cu elements.The strong anomaly of As,Sb and Hg indicates the upper and the leading edge of the ore body,which is closely related to gold mineralization.Therefore,the tectono-geochemical characteristic of Liyuan gold deposit was analyzed,which has certain instruction significance in metallogenic prediction and enriching the geochemical model of gold deposit in the study area.

Key words: multivariate statistical analysis, element anomaly combination, anomalous structure, tectono-geochemistry, Liyuan gold deposit, Taihang Mountain
