14572.甘肅莊浪靜寧鐵礦成礦地質(zhì)特征及找礦方向研究

1、論文題目：甘肅莊浪靜寧鐵礦成礦地質(zhì)特征及找礦方向研究專(zhuān)業(yè)：礦產(chǎn)普查與勘探碩士生：端木輝（簽名）指導(dǎo)老師：王貴榮端木合順（簽名）摘要甘肅莊浪靜寧鐵礦床位于甘肅省東部山地與黃土高原的過(guò)渡地帶，大地構(gòu)造屬于祁連造山帶東部。該區(qū)大部分被黃土覆蓋，僅在深切溝壑中有少量零星基巖出露，歷年來(lái)找礦沒(méi)有大的突破。甘肅莊浪靜寧鐵礦的發(fā)現(xiàn)，預(yù)示了在該地區(qū)開(kāi)展找礦工作具有良好的前景。本文以該鐵礦床為對(duì)象，進(jìn)行典型的礦床成礦特征研究、成礦規(guī)律總結(jié)和找礦方向的探討

2、，對(duì)推動(dòng)甘肅東部黃土覆蓋區(qū)找礦工作具有重要的理論及實(shí)踐意義。收集整理了近年來(lái)祁連造山帶（東段）的一系列研究成果，并且結(jié)合礦區(qū)已有資料，總結(jié)出了礦床的成礦地質(zhì)背景；通過(guò)巖石薄片鑒定、Harker圖解分析、特征參數(shù)計(jì)算等方法，研究得出了基性巖體的巖石學(xué)特征、基性巖體地球化學(xué)特征以及基性巖礦物與成礦關(guān)系等，從而構(gòu)建出了本礦區(qū)的成礦地質(zhì)特征；根據(jù)已有的成礦地質(zhì)特征，分析得到了適合本礦區(qū)的控礦因素和確定了礦床的成因類(lèi)型。針對(duì)礦區(qū)對(duì)今后找礦方向的實(shí)

3、際需求，在對(duì)國(guó)內(nèi)同類(lèi)型礦床進(jìn)行對(duì)比的基礎(chǔ)上，結(jié)合礦區(qū)的磁法異常和地質(zhì)特征情況，得出了礦區(qū)的找礦方向。關(guān)鍵詞：莊浪靜寧鐵礦含礦巖體控礦因素成礦地質(zhì)特征找礦方向研究類(lèi)型：應(yīng)用研究型Subject：GeologicalacteristicsProspectingDirectionofIronDepositinZhuanglangjingningGansuProvinceSpecialty：MineralProspectingExplation
