【摘要】：格陵蘭是世界上重要的巨型多金屬成礦帶之一,Jameson Land盆地位于該成礦帶的東部,該區(qū)Cu、Pb、Zn等金屬地表礦化特征明顯、礦化強度大,分布范圍廣、厚度大。區(qū)內(nèi)礦化點也較多,已發(fā)現(xiàn)近6~10個銅、鉛或鋅礦化層。Quensel Bjerg礦區(qū)位于Jameson Land盆地的東部。本文通過系統(tǒng)的野外地質(zhì)調(diào)查、流體包裹體顯微測溫以及C-O、S穩(wěn)定同位素分析,認(rèn)為Quensel Bjerg礦區(qū)成礦流體性質(zhì)為中低溫、中低鹽度流體,流體來源于大氣降水和地層水(海水)的混合,碳來源于海相碳酸鹽巖的溶解,成礦物質(zhì)來源于Ravnefjeld組頁巖、圍巖(灰?guī)r)及下伏地層,該礦床屬于沉積巖容礦的沉積-改造型層狀銅鉛鋅多金屬礦床。
[Abstract]:Greenland is one of the world's important giant polymetallic metallogenic belt, located in the eastern part of the Jameson Land basin metallogenic belt, the area of Cu, Pb, Zn and other metal surface mineralization characteristics, mineralization intensity, wide distribution, large thickness. Zone mineralization points are more, have been found near 6~10 copper or lead..Quensel Bjerg ZINC MINERALIZATION layer mining area is located in Jameson Land basin to the East. Through field geological survey system, fluid inclusions and C-O S analysis, stable isotope, ore-forming fluid properties that Quensel Bjerg is in low temperature, low salinity fluid, the fluid is from meteoric water and stratum water (sea water) mixed. Dissolved carbon derived from marine carbonate rocks, the ore-forming materials come from shale rock group Ravnefjeld (Hui Yan), and the underlying strata, the sedimentary deposit belongs to sedimentary hosted layered transformation type Cu Pb Zn polymetallic deposit.
