古俯沖帶背景下的殘餘地幔巖的pges配分以pd ， pt明顯虧損和ir ， ru相對富集為特徵，而部分熔融產物的玄武巖和基性巖脈則呈現相反的ir ， ru明顯虧損和pd ， pt相對富集特徵。俯沖帶中流體的參與一方面增加了部分熔融程度，有利於pd ， pt從原始地幔進入熔融相另一方面，流體的作用使得pd ， pt相對于ir ， ru遷移活動性效率提高，造成地幔巖中High - mg volcanic rocks approach the primitive mantle compositions, and their magmatic source is close to the composition of bse, derives from the lower mantle and formed by this type - mantle rocks " fractional melting highly ( > 25 % ). high - mg volcanic magma, formed in the axis of the emei mantle plume, underwent the crystallization differentiation of olivines and some pyroxenes ; some olivines reflect fair cumulus crystallization
高鎂火山巖接近於原始巖漿的組成，巖漿源區與地球平均成分bse的成分特徵相近，起源深度為下地幔，為該地幔巖較高程度的部分熔融（ 25 ）而形成的。高鎂火山巖處于地幔柱的軸部，經歷了橄欖石及一定程度的輝石分異結晶，並且橄欖石顯示出一定的堆晶作用。Ultramafic rock fragments, which almost is altered to ophite, distributed in structural zone and displayed structural lens. so far, 9 fragments were discovered and mapped in nujinshan and bujing area ultramafic rock can be divided two kinds according to it ' s geochemical characteristics. one can be correlated with metaperidotite, which represented residual part that primary pyrolite underwent moderate partial melting, from some representative ophiolite melange in the world
按超鎂鐵巖類的地球化學特徵可將其劃分為兩類：一類具有較高而穩定的mgo 、較低的al _ 2o _ 3 、極低的cao ， m f值為8 . 0 ? 8 . 4 ，按標準礦物組合進行分類可定為方輝橄欖巖，且均為fa _ （ 100 ） 、 en _ （ 100 ）的鎂質端元組分；可與世界上一些典型的蛇綠巖套中變質橄欖巖進行對比，代表了原始地幔中等部分熔融作用后殘余物。Within my lifetime, the red planet has been transformed from a point in the night sky into a land of towering volcanoes, dried - up riverbeds, ancient lakes and windswept lava plains
在我有生之年，紅色行星從夜空中的一點，搖身變成一個世界充滿了高聳火山、乾枯河床、古老湖泊和飽受風襲的熔巖平原。Such features can be ascribed to lower degrees of partial melting and greater melting depths. in particular, the decoupling between the lowest nag and highest tig tends to indicate residual jadeite during melting process so that na behaved as a moderately compatible element to lower the naao concentration in these rocks. this is consistent with the ree patterns in the high - ti diabases that have the highest ( gd / yb ) cn ratios than other two groups, which suggest a more important role of residual garnet in generation of the primary magmas
運用mgo = 8進行標準化，結合巖石成因理論討論了三大系列輝綠巖的形成相對深度和熔融比例，其中高ti系列的原始巖漿形成深度大，熔融比例小，源區相對最為富集易熔組分；低ti系列的熔融深度最淺，比例最大，源區相對虧損易熔組分；過渡ti系列則介於前兩大系列之間。The land along the edges generally retains its altitude, as this was determined by the thickness of the plates, thus its boyancy on the sea of lava
