It is suggests that in the Shigujian pluton, the designations of plagioclases are 15 - 25, the plagioclases are all oligoclase; the biotites are Mg-biotites, and most of the amphiboles are edenitic amphiboles or edenite; paragenetic ...

结果表明:(1)石鼓尖侵入岩中,斜长石成分较稳定,共生角门石和黑云母为岩浆平衡结晶的矿物;(2)天堂寨和九资河侵入岩中,部分斜长石和黑云母可能为熔蚀残留矿物,角闪石属于火成岩区的新生矿物,可能为斜长石和黑云母发生熔融反应所形成;(3)三个侵入体的岩石均为岩浆成因。

So, endomycorrhiza was formed betweenD. candidum roots and strain AR-15. There were several nucleoli and nuclei in thecortical cells next to exodermis when a nucleus transfer across the cell wall wasobserved. Sometimes plant roots were damaged by strain AR-15. The microstructure of D.

真菌AR-18倾向于根生长,在根周围形成了一个包围圈,由根被细胞侵入外皮层通道细胞及其相邻的皮层细胞,然后向其他皮层细胞推进;真菌菌丝也可由皮层细胞侵入外皮层细胞。

For intrusion, only those hypabyssal intrusion rocks with thickness over 15 m, having effective fracture zone, and inserted in or immediately adjacent to mature source rock, and those dikes near contemporaneous fault and within buried hill fracture zone have favorable reservoir forming condition s.

在大量的侵入岩体中,只有侵入岩厚度大于15m,具有有效裂缝带发育、直接嵌置或紧邻成熟烃源岩的浅成侵入岩,以及分布在同生断层附近的、潜山裂缝发育带中的脉岩具备有利成藏条件。

The comparative studies of lithogeochemistry for the volcano-intrusive complexes both from Jiulongzhang and from xiangshan reveal that the chemical compositions of the volcano intrusive complexes in the two areas are very close, and the trace element spidergrams and REE patterns basically coincide with each other. It is also shown that the two volcano-intrusive complexes have the same source features and the active continental margin tectonic settings. At the same time, it is found that, from early volcanic magma activities to later intrusive magma activities, the content of SiO2 and the Rb/Sr ratio decreased, on the contrary, the content of MgO and the ratios of K/Rb, Ba/Rb and LREE/HREE increased. It is shown that the hypabyssal or ultra-hypabyssal intrusives are not the products of the volcanic magmatic differentiation.

两地区的火山-侵入杂岩的岩石化学成分及其变化特点极为相近,微量元素蛛网图和稀土配分型式也基本一致,它们具有相似的岩浆过程和统一的活动陆缘构造背景;同时,从早期火山岩浆活动到晚期浅成-超浅成岩浆侵入活动,其w(SiO2)和w/w的值降低,而w以及w/w、w/w和w/w的值增高,晚期浅成-超浅成侵入岩与早期火山岩没有直接的分异演化关系。

High pressure and temperature experiment show that lamprophyric melt and orthophyric melt mix with each other under high pressure and seperate under low-pressure.

结合哀牢山断裂带富碱侵入岩的地质地球化学资料,论证了煌斑岩与富碱侵入岩为富集地幔不同部分熔融程度的产物;高温高压实验表明,煌斑岩熔体和花岗斑岩熔体在高压条件下发生混合,低压条件下出班分离,加上有关的地球化学判别,推测岩浆混合作用是本区煌斑岩与花岗斑岩(富碱侵入岩母岩浆同化分异结晶作用的产物)密切共生的主要因素。

The results show that during the landfalling ing and northward going process of Matsa, the cold air in its northwest side first rotated along the typhoon circulation from the north to the south, and then intruded northward form the south into warm center of Matsa gradually, and at the same time in the vertical direction there were cold airs systematically/slantly descending from the middle-upper troposphere and intruding into the typhoon circumfluence at the low level, which at last resulted in the extratropical transition of Mstsa.
