garnet-rocks 中文意思是什麼
-
On the basis of the study on the petrology, trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. one is the basanite - alkaline basalt - olivine tholeiite magma series, which are generated by partial melting from spinel iherzolite ; the other is nephelinite magma - alkaline picritic basalt magma, which are generated by partial melting of the garnet iherzolite
巖石化學、微量元素、同位素地球化學證據都表明，華北、華南地區的火山巖根據源巖和局部熔融程度的不同，可以分為兩個原生巖漿系列：一個是源巖為尖晶石二輝橄欖巖，隨著局部熔融程度的增加，形成的碧玄巖巖漿-堿性玄武巖巖漿-橄欖拉斑玄武巖巖漿；另一個是源巖為石榴石二輝橄欖巖，隨著局部熔融程度的增加形成的霞石巖巖漿-堿性苦橄玄武巖系列。 -
The assemblage of garnet - diopside in the silicate alteration rocks is different from that in the skarn of traditional idea
硅酸鹽蝕變巖中的「石榴子石透輝石」組合與傳統理解的「夕卡巖」內的相同組合名同實異。 -
The distinctive shimmer of the rocks and their marble - size crystals of red garnet, black hornblende and sage - green diopside in most places attest to metamorphic tortures nearly as intense as those experienced at akilia
伊蘇瓦巖石的許多特徵，如特殊的光澤與彈珠大小的各式結晶，包括紅色的石榴石、黑色的角閃石、鼠尾草般綠色的透輝石等，在在說明它經歷的變質作用幾乎與阿基利亞巖石一樣強烈。 -
2 both the hanging wall and the footwail rock of ore bodies are garnet biotite schist, protoliths are alkaline volcanic rocks ( tracyh andesite ). according to characteristics of trace elements assemblages and the setting of tectonics, these alkaline volcanic rocks were derived from the lower degree melting of metasomatic and enriched mantle ( eml ) in the initial stage of middle proterozoic epoch. they strongly enriched in large ion lithophile elements ( lile ), such as ba
2 、礦體頂、底板圍巖（石榴石黑雲母片巖、鈉長黑雲母片巖等）的原巖為堿性火山巖（粗面安山巖） ，相對富集大離子親石元素ba 、 cs 、 rb 、 k 、 lree及貧zr 、 sr 、 ti 、 hf 、 hree ，為早元古代末期-中元古代早期交代富集地幔低程度部分熔融所形成的堿性火山巖。 -
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。
