較全面地提出了判別造山帶成熟拆沉作用發生的標志,特別是根據對我國典型造山帶的總結分析,提出了一些新的標志,如環狀超基性一基性一中酸性雜巖體;局部雙峰式大陸裂谷型火山活動;二長花崗巖、堿性花崗巖和奧長環斑花崗巖;地殼局部短暫下沉;等等。The rapakivi granites have a number of petrological peculiarities.
環斑花崗巖具有若干巖石學的特徵。There is a close relation between mesozoic tectonic evolution, fluid evolution, petrogenesis and mineralization in the manzhouli - e ' erguna region in the northeast of the northern orogenic belt, china, and three evolution stages of the mesozoic tectonic - fluid - petrogenetic and metallogenetic system are proposed out : 1 ) acompanied by ree and cu mineralization, the calc - alkaline volcanic rocks and mantle - crust mixed type granite occurred under the regional tension tectonic background caused by the mongolia - okhotsk residual ocean that was closing in scissors form in the early - middle jurassic. 2 ) acompanied by pb, zn and ag mineralization, the calc - alkaline and alkaline volcanic rocks occurred under the regional shear - compression tectonic background in the late jurassic. 3 ) acompanied by u, f, pb, zn and ag mineralization, the caic - alkaline and alkaline volcanic rocks occurred under the regional tension tectonic background in the early cretaceous
摘要本文討論了北方造山帶東北段滿洲里額爾古納地區及其毗鄰區中生代構造流體成巖成礦系統及其演化的三個不同階段: 1 )早中侏羅世張性「似裂谷環境」下所形成的中基性堿性火山巖、同熔性花崗巖及深源流體活動形成的稀土礦床和斑巖性銅鋁礦床; 2 )晚侏羅世擠壓剪切環境下所形成的酸性火山巖、斑巖類及深源流體活動所形成的鉛鋅銀礦床; 3 )早白堊世張性環境下所形成的基性堿性火山巖及深源流體活動所形成的鈾礦床、金銀礦床及螢石礦床。Study on petrology, geochemistry and isotope chronology shows that the metallogenesis is closely related to granite - porphyry, which belongs to the early ordovician adakite formed in volcanic arc
花崗斑巖與成礦作用關系密切,從巖石學、巖石化學、年齡學等方面對花崗斑巖進行了研究,認為花崗斑巖屬于志留世早期形成於火山弧環境的埃達克巖。分享友人
