酸性熔巖及同質凝灰巖,屬鈣堿性系列,且高鉀富鋁。The control of the deep - seated structural - magmatic process over the metallogenic system around the middle - lower yangtze river reaches is shown as : ( 1 ) the mantle uplift belt is closely related to the general geological background of the metallogenic system ; ( 2 ) the primitive magma originated from different parts of the mantle uplift belt ( mantle ridge or mantle slope ) shows differences in style of formation and composition and results in different magmatic series and metallogenic subzones, respectively ; ( 3 ) the varying depths of structural - magmatic chambers may form a " three - layered structure " ( central type, network - like and ring - like ) and this is the primary factor that controls the different magmatic series and the concerned cluster of ore deposits ; ( 4 ) the alkaline basaltic magma derived from the mantle ridge forms high - potassium and calcium alkaline magma and shoshonitic magma due to its altering intensity of afc process with the lower crustal material, which has something to do with the copper - gold and iron - sulphur metallogenic subsystems, respectively
深部構造巖漿作用對長江中下游成礦帶安徽沿江地區成礦系統的控製表現為: ( 1 )地幔隆起帶與成礦系統的總體地質背景的演變密切相關; ( 2 )源於地幔隆起帶不同部位(幔脊與幔坡)的原始巖漿,其生成方式和物質組成不盡相同,它們分別產生相應的不同巖漿巖系列和成礦亞帶; ( 3 )不同深度的構造巖漿房組成中心式網格式環帶式「三層結構」 ,是控制區內不同巖漿巖系列及有關礦床集中分佈的主要因素; ( 4 )源於地幔隆起帶脊部的堿性玄武巖漿,由於與下地殼物質發生的afc作用強度不同,形成了高鉀鈣堿性巖漿和橄欖安粗巖漿,分別與銅、金成礦亞系統和鐵、硫成礦亞系統有關。At last the rhythm of yanshanian volcanic rocks is classified into three series such as alkaline basalt, hkca, calc - alkaline shoshonite. 4. based on the study of rock series, assemblage of igneous rock, characteristic of geochemistry, trace effect of isotope, the yanshanian volcanic rocks of yanshan - liaoning area are mainly calc - alkaline series, which should belong to the products of near continental margin of intracontinental tectonic setting
3 、在火山活動節律的劃分、區域對比的基礎上,研究了各級節律火山巖的巖石學、礦物學、地球化學和同位素地質學特徵,將研究區燕山期火山巖劃分為堿性玄武巖系列、高鉀鈣堿性系列和鉀玄巖系列。On the basis of detailed and systematic studies on the petrography, major and trace elements and sr - nd isotopic data of mesozoic volcanic rocks, especially the mafic volcanic rocks in yanshan area, we successfully studied the deep processes related to magma generation and their relationship with shallow - level tectonic evolution. the major conclusions are summarized as below. 1
論文通過對燕山地區中生代火山巖,特別是中基性火山巖,進行詳細而系統的巖石學、主微量元素地球化學特徵和sr - nd同位素組成特徵的研究,主要取得了以下研究成果: 1燕山地區中生代( j - k )火山巖為一套鈣堿性-高鉀鈣堿性-橄欖安粗巖系列巖石。分享友人
