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

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。
So caleb now chose not the valleys, the fruit and the grapes. no, he looked at those rugged mountains

All water conveyance and water discharge structures are designed to locate at right bank strip ridge, due to special topography and land form. large excavation area and steep slope raising from close plan locations of adjacent structure lead to slope stability. in general, slope stability analysis and treatment are concerns of zipingpu project
由於其特殊的地形、地貌,工程的各輸、泄水建築物共7條隧洞均布置在右岸條形山

Also, i see that their long shadows are on the hollow ridge on the opposite side of the road, and are on the hill above it, and are like the shadows of giants
我還看到他們很長很長的影子落到路那邊凹下的山脊和隆起的山坡上,像是些巨人的影子。
