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，歷年來找礦沒有大的突破。甘肅莊浪靜寧鐵礦的發(fā)現(xiàn)，預(yù)示了在該地區(qū)開展找礦工作具有良好的前景。本文以該鐵礦床為對象，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、，對推動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；通過巖石薄片鑒定、Harker圖解分析、特征參數(shù)計算等方法，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型。針對礦區(qū)對今后找礦方向的實(shí)

3、際需求，在對國內(nèi)同類型礦床進(jìn)行對比的基礎(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型：應(yīng)用研究型Subject：GeologicalacteristicsProspectingDirectionofIronDepositinZhuanglangjingningGansuProvinceSpecialty：MineralProspectingExplation
