Analysis of mineralization geological characteristics and ore control factors in deep mining area author

针对深部开采区矿化条件较复杂的问题,为此提出深部开采区矿化地质特征及控矿因素分析。深部开采区矿化在地层上主要以古生代-中生代沉积地层为主;褶皱构造主要形成于印支期,而断裂构造大部分形成于印支期和燕山中-晚期;深部开采区的岩浆活动分成两期,早期:150Ma^135Ma;晚期:135Ma^114Ma。侵入岩作为深部开采区矿化控矿最主要的控矿因素,为矿化提供了矿源、硫源及其传输介质。

In view of the complex mineralization conditions in the deep mining area,this paper puts forward the analysis of the mineralization geological characteristics and ore control factors in the deep mining area.The mineralization in deep mining area is dominated by Paleozoic Mesozoic sedimentary strata;fold structure is mainly formed in Indosinian period,while fault structure is mostly formed in Indosinian period and middle late Yanshan period;magmatic activity in deep mining area is divided into two stages,early stage:150Ma^135Ma;late stage:135Ma^114 Ma.Intrusive rock,as the main ore controlling factor of mineralization in deep mining area,provides ore source,sulfur source and transport medium for mineralization.
