Late Jurassic trachyandesites from Tiaojishan Formation in Western Hills of Beijing are similar to adakitic rocks in geochemical characteristics.北京西山晚侏罗世髫髻山组粗安岩具有高的SiO2 (>5 6 % )、Al2 O3(16 。
Excepting a few high-K 2O rhyolite, trachydacite and trachyte, latites commonly having clino and orthopyroxenes phenocrysts are superior in quantity and distribution.除少量的高钾流纹岩、粗面岩和粗面英安岩外，在数量和分布上以普遍含二辉石斑晶的安粗岩占优势。
This paper compares latitic series of the Yan-shanian tectonic cycle in Beijing region with those of the generally accepted latitic series bothat home and abroad, then discusses the characteristics of the different volcanic rock series,and lastly points out that the latitic series is an independent volcanic rock series which maycoordinate with the tholeiite series,calcalkali.安粗岩系是指由钾质粗面玄武岩、橄榄玄武粗安岩、安粗岩、粗面岩和高钾流纹岩等富钾岩石组成的火山岩系列，本文以北京地区燕山构造旋回安粗岩系火山岩为例，通过与国内外公认的安粗岩系比较，以及对不同系列火山岩特征的对比分析，明确提出：安粗岩系是可以与拉斑玄武岩系、钙碱性岩系和碱性玄武岩系并列存在的独立的火山岩系列，它有自己特定的产出环境，有别于其他岩系的岩石类型、岩石组合及物质成分等特点。
Their petrology,lithochemistry and trace element geochemistry revealed that,though,the rock series changed from shoshonite to quartz syenite,syenite and alkaline-feldspar granite,they did not belong to ultrapotassic rocks(K2O/Na2O<2,w(MgO)<3%).对二者进行岩相学、岩石化学及微量元素地球化学的比较研究可知:岩石组合上从橄榄安粗岩系向正长岩和碱性花岗岩变化,不属于过钾质岩石(K2O/Na2O<2,MgO<3%);微量元素和稀土配分形式大致相同(富集Rb,Th等大离子亲石元素,亏损Ti等高场强元素,LREE富集);主量元素显示具有同源岩浆结晶分异的特征(Al2O3,MgO,FeO*,TiO2,CaO,P2O5都与SiO2呈现良好的负相关)。
The rock assemblages of the Bayinbuluke formation are mainly alkaline basalt-thick andesite-alkaline rhyolite.火山岩岩石组合以碱性玄武岩-粗安岩-碱性流纹岩为主.
Discovery of the basaltic andesite-high-K basaltic andesite-trachyandesite association in the Yuximoiegai Daban, West Tianshan and its geological significance.西天山玉希莫勒盖达坂玄武安山岩-高钾玄武安山岩-粗安岩组合的发现及其地质意义
