查询词典 syenite

Detailed geology- petrology-mineralogy study shows that late Triassic-early Jurassic granites can be divided into 4 groups: granodiorites, monzonitic-K syenogranites mainly, alkali feldspar-alkali granites and syenite, Middle Jurassic granites is composed of quartz diorites-granodiorites and monzonitic granites, the main rock type includes granodiorites and monzogranites; Early Cretaceous granites include alkali gabbro, alkali granites and granodiorites, and these rocks composed bimodal igneous rock group.

详细的地质-岩石矿物学研究表明，晚三叠-早侏罗世花岗岩可以划分成四种岩石组合，即花岗闪长岩组合、二长花岗岩—正长花岗岩组合、碱长花岗岩—碱性花岗岩组合和正长岩组合，其中以二长花岗岩—正长花岗岩组合为主；中侏罗世花岗岩由石英闪长岩-花岗闪长岩组合和二长花岗岩组合构成，岩石类型以花岗闪长岩和二长花岗岩为主；早白垩世出现了碱性辉长岩、碱性花岗岩和花岗闪长岩，构成双峰式火成岩组合。

The 207Pb/206Pb age (593Ma) of single zircon of quartz-syenite porphyry reflects that the intrusion of subvolcanics is accompanied by capture of paleo-zircon of the basement rocks, implying that the Precambrian continental basement possibly exists below Aqishan-Yamansu volcanic island arc.

而石英正长斑岩单颗粒锆石207Pb/206Pb年龄值(593Ma)反映了岩体侵位过程中捕获了基底岩石中古锆石的年龄信息。进一步推测在阿齐山－雅满苏火山岛弧之下可能存在前寒武纪陆壳基底。
