甘肃省中祁连党河流域铜多金属矿成矿地质条件分析
|
摘要
甘肃省中祁连党河流域是我国重要的成矿带之一,矿产资源丰富,矿床类型发育齐全,在这一区域内,蕴藏有丰富的矿产资源如：铜、镍、铬、金、铅、锌等。本文结合甘肃省地调院对工作区开展的1：5万矿产远景调查,大致查明区内铜多金属矿的成矿地质条件、地球物理、地球化学、矿产特征及矿产分布规律,圈定物化探异常和矿化有利地段,并进行综合研究,总结出研究区内铜多金属矿的找矿标志和成矿规律。
本文主要是对中祁连党河流域铜多金属矿综合地、物、化、遥的各种数据,依托RGmap数字填图系统以及MAPgis技术平台,以典型的铜多金属矿化点来分析甘肃省中祁连党河流域铜多金属矿地质特征。
本文运用现代区域成矿学与超大型铜多金属矿床理论深入研究区域成矿地质背景和区内典型成矿区带及矿床成矿环境、成矿因素、成矿过程以及成矿物质,阐明研究区内矿床时空分布规律,寻找铜多金属矿的找矿标志,以进行区域成矿预测与资源潜力分析。文章应用基础地质和矿床地质的理论和有关技术方法,着重研究本地区中的铜、金的成矿条件和找矿信息,推断可能存在的矿床(矿体)及其基本特征。
对工作区铜多金属矿的成矿预测主要应用地质类比法,研究总结本地区已知典型铜多金属矿床的成矿地质环境和控矿因素,以作为类比并推断未知有矿地区的成矿可能性的依据。
通过本区成矿地质背景分析,成矿元素的分布规律的研究提出了主攻矿种和类型,有希望突破的矿种主要为铬、砂金,其分布广而富集,找矿标志明显,而内生金矿成矿远景最为可观,应加强内生金的研究。同时注意寻找新的脉金产地,如与奥陶纪蚀变火山岩有关的火山—潜火山热液型金矿,其次为铜、铬、铅锌。
DangHe basin in gansu province is one of important the metallogenic belt, rich mineral resources, the copper deposit types development are completement, in this area, contain is rich in minerals such as copper, nickel, chromium, gold, lead, zinc, etc. Based on the working area in gansu province 1:50000 mineral prospect survey,found zone cu polymetallic deposits of ore-forming geological conditions, geophysical, geochemical and mineral characteristics and mineral distribution rule is delineated, geophysical and geochemical prospecting anomalies and mineralization favorable location, and carry on comprehensive study, summarizes research district of cu polymetallic deposits prospecting marks and ore-forming regularity.
This paper mainly DangHe basin in qilian cu polymetallic deposits comprehensively, geophysical, geochemical and remote-sensing all kinds of data, relying on digital mapping system and RGmap MAPgis technology platform, with typical cu polymetallic deposits in the point to analyze DangHe basin in gansu province dang geological features cu polymetallic deposits.
This paper USES the modern regional metallogenic learn and very large copper polymetallic deposits theory thorough research area ore-forming geological background and zone typical mineralization zones and metallogenic environment, metallogenic factors, ore-forming process and ore-forming materials research in deposits, expounds spatial and temporal distribution regularity, looking for cu polymetallic deposits in the prospecting marks, regional metallogenic prediction and resource potential analysis. Article application foundation geology and ore deposit geology theories and relevant technical method in this region, this paper studies the copper, gold metallogenic conditions and prospecting information, deduce the possible existence of ore deposits (orebody) and its basic characteristics.
Also cu polymetallic deposits of metallogenic prediction main application geological analogy method, sum up the region known typical copper of polymetallic mineralization geological environment and the ore-controlling factors, as analogy and infer that unknown have ore region the basis of metallogenic possibility.
Through analysis of metallogenic geologic background area, the distribution of ore-forming elements proposed the main mineral resources and research, hopeful breakthrough type for main chromium, ShaJin minerals, its wide distribution and enrichment, ore-prospecting endogenous evident, and gold metallogenic prospect, we should strengthen the most significant of endogenous gold. Also look for new MaiJin origin, such as the altered volcanic relevant volcano-dive volcanic hydrothermal type gold deposits, followed by copper, chromium, lead and zinc.
