【摘要】：羊拉銅礦床是金沙江構(gòu)造帶內(nèi)的代表性銅礦床,其礦體產(chǎn)出明顯受到斷裂及層間破碎帶控制。本文重點(diǎn)對羊拉礦床里農(nóng)—路農(nóng)接合段的3450 m中段進(jìn)行了構(gòu)造地球化學(xué)研究,R型聚類分析和因子分析表明:該中段斷裂構(gòu)造巖微量元素主要表現(xiàn)為地層巖石微量元素組合(Nb、Hf、Ta、Zr、Rb、V、Sc、Th、Cs、Be、Ga、Li、REE、Ba、Cr、U、Co、Tl、Ge、(Ag、In、Sn、Cu)),中-高溫成礦元素組合(Cd、Pb、Bi、Ag、As、Sn、In、Sb、Cu、Zn、Ge、Tl、Mo、U、(Co、Ga))和地質(zhì)意義不明元素組合(Ni、Sr),揭示羊拉礦床的形成可能經(jīng)歷了成礦前期成礦元素的初步富集和成礦期退夕卡巖化過程中成礦元素的沉淀成礦。構(gòu)造地球化學(xué)異常的分布則指示了找礦預(yù)測靶區(qū)。
[Abstract]:Yangla copper deposit is a representative copper deposit in Jinshajiang structural belt, and its ore body is obviously controlled by faults and interlayer fracture zones. This paper focuses on the structural geochemistry of the 3450 m middle segment of the Linong Lunong junction section of the Yangla deposit. The cluster analysis and factor analysis show that the trace elements of the fault tectonite in the middle segment are mainly stratigraphic and lithologic trace elements. 鍏冪礌緇勫悎(Nb,Hf,Ta,Zr,Rb,V,Sc,Th,Cs,Be,Ga,Li,REE,Ba,Cr,U,Co,Tl,Ge,(Ag,In,Sn,Cu)),涓，
