Jianchaling nickel deposit that respected with it is originally devided into magma type deposit, its metallogenesis include magma differrentiation - crystalization, sulfurization process, magma melt - segregated, and hydrothermal process. but melt - separated ore - forming poorly developed, and hydrothermal process is subordinate, the assimilation and contamination of country rocks have special significance to the formation of this ore deposit
與之有關的煎茶嶺鎳礦床成因上屬巖漿礦床，其成礦作用有巖漿分結作用、硫化作用、巖漿熔離作用及熱液作用等，但巖漿熔離成礦作用不發育，熱液作用僅佔次要地位，富硫圍巖的同化混染對礦床的形成有特殊的意義。 -
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。 -
The paper based on synthesize domestic and foreign ' s study achievement about basalt, systematical review basalt research history, present condition about basalt formation contributing factor and it ' s magma source area quality, uses the basalt to distinguish the earth ' s mantle type, the connection basaltic magma evolution and continent dynamics, and uses the basalt to distinguish tectonic environment
