中文拼音 [demànyǎcéng]
地幔亞層
英文
mantle substratum-
The copper, iron, nickel and silver deposits might be assigned to four metallogenic series : i. the metallogenic subseries of copper, molybdenum, gold, silver deposit related to late devonian - early carboniferous basic - intermediate - acid hypabyssal intrusive - eruptive rocks ; ii. the metallogenic subseriesof iron, copper, zinc deposits related to early carboniferous basic - intermediate - acid volcanic - intrusive rocks ; iii. the metallogenic subseries of copper, silver, iron deposits related to middle - late carboniferous basic - intermediate - acid volcanic - intrusive rocks ; iv. the metallogenic subseries of copper, nickel and platinum group deposits related to late carboniferous - early permian basic - ultrabasic rocks ; 3, division of regional major metallogenic belts on the basis of the previous work conducted and by following the principles, grounds and methods of the division of metallogenic belts, areas and fields, . in light of this, metallogenic belts of grade iv were divided
1 、按照成礦系列理論的學術指導思想，將研究區華里西期銅礦床成礦系列劃分為四個成礦系列亞系列： 、晚泥盆?早石炭世延東?土屋?三岔口與中酸性巖漿侵入活動有關的cu 、 mo 、 au礦床成礦亞系列、早石炭世與巖漿作用有關的鐵、銅、金、銀礦床成礦亞系列、中石炭世與巖漿作用有關的cu 、 fe 、 ag 、 au礦床成礦亞系列、晚石炭世-早二疊世與幔源基性?超基性巖有關的銅、鎳、鉑族礦床成礦亞系列並從地層、巖漿巖、控礦構造、地球化學、成礦特徵等方面對各成礦亞系列進行了詳細論述。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。
