陆壳

The acid volcanic rocks of the Early Cretaceous Shangkuli Formation belong to continental crust anatexis type ones (S-type volcanic rocks) and may have formed by compression and migration of the Indian-Australia plate toward the NNE and delamination of the lower crust caused by the lithospheric extension in eastern China.

They have A/CNK values of 0.9～1.2, suggesting aluminum saturation or ersaturation, and are enriched in LREE and LILEs and depleted in HFSEs. Their δEu values are 0.11～0.32, evidently indicating plagioclase fractional crystallization.(87Sr/86Sr)i ratios and εNdvalues are 0.707?9～0.716?1 and -6.90～-7.70 for volcanic rocks, and 0.7086～0.7098 and -7.10～-7.68 for quartz syenitic porphyrite, respectively, implying that all the igneous rocks from the Yandang Mountain were evolutional products of co-magmas, and derived mainly from the crust, mixed however with mantle components.

岩石富集轻稀土元素和大离子亲石元素，相对亏损高场强元素；δEu值为0.11～0.32，表明岩浆经历了以斜长石为主的强烈结晶分异作用；火山岩(87Sr/86Sr)i为0.707 9～0.716 1，εNd为-6.90～-7.70，中央侵入体石英正长斑岩(87Sr/86Sr)i为0.708 6～0.709 8，εNd为-7.10～-7.68，表明它们是同源岩浆不同阶段分异演化的产物，物质来源主要为陆壳，但也有地幔物质参与。

The higher subduction velocity advantages the low temperature in the subduction belt. In addition, it takes less time for the crust rock to subduct the deep and then return to shallow. The low temperature and the short time are benefit to forming and reserve the ultrahigh\|pressure metamorphic rocks.

板块持续的高速俯冲，不仅可以使得俯冲带形成低温环境，而且在陆壳岩石俯冲到地幔经受超高压变质作用后返回地表浅部的过程中，超高压变质岩在地幔滞留的时间短，为超高压变质岩的形成提供了必要条件。

It shows that the magma forming the syenite in the Luzong basin was derived from a deep source, most likely resulting from the partial melting of an alkali basalts along the deep fault, and obviously contaminated by continental crust material.

反映了庐枞盆地正长岩类成岩物质来源较深，是来自富集地幔的碱性玄武岩浆在沿深大断裂上升侵位过程中，受到部分陆壳物质的混染而成。

Basalts plot in tholeiite in A.I-Al〓O〓 diagram. They have enriched LREE patterns without negative Eu anomaly. Their Zr/Y=4.4～6.5,〓=0.70790～0.70146, Th＞＞Ta,εNd values are between -1.8 and +3.7, indicating continental contamination. Pb isotope characteristics are close to that of typical tholeiitic flood basalt in the world.
