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。
