查询词典 syenites

This rock zone, with a NE striking, the whole length of 1 400 km and the width of 100～150 km, is characterized by not onlyalkaline rocks (analcite biotite olivine melilitites, leucititic alnoites, nephelite syenites, aegirite augite syenites, melanite syenites, riebeckite syenite and aegirite bearing quartz syenites) and alkaline granite (riebeckite granite, and aegitite augite riebeckite granite), but also a lot of syenites, monzonites and alkaline feldspar granites or miarolitic K feldspar granites.

该岩带全长约1400km，宽100～150km，不仅发育有狭义的碱性岩(方沸黑云橄榄黄长岩、白榴黄长煌斑岩、霞石正长岩、霓辉石正长岩、黑榴石正长岩和含霓石石英正长岩)和碱性花岗岩(钠闪石花岗岩、霓辉石钠闪石花岗岩)，还发育有大量的正长岩类二长岩类碱长花岗岩或晶洞钾长花岗岩。

The paper presents distribution of nepheline syenites and theirtectonic settings, rock assembladges, mineral associations and geochemisical characteristics, discusses the relationship between the minerological characteristics of main minerals and their host rock.

Taxkorgan alkaline belt is made up of alkaline syenites, alkaline syenitoids and alkaline to sub-alkaline granites, with aegirine-augite syenite, diopside syenitoid and biotite adamellite as their representative rocks.

塔什库尔干碱性岩带主要由碱性正长岩类、碱性花岗岩类和碱性—偏碱性花岗岩类组成，代表性岩石类型为霓辉石正长岩、透辉石正长花岗岩和黑云母二长花岗岩。

Geochemical data indicate that the syenites were originated from the remelting of the underplated mafic lower crust which composition had been changed by the asthenospheric upwelling.

地球化学数据表明，正长岩体是受软流圈组分改造过的底侵基性下地壳重熔后经结晶分异的产物。

The Mazhashan syenites in the Bachu area were formed in the Late Permian with the zircon SHRIMP age ranging from 286 to 277Ma, and these ages are consistent with the ages (300-260 Ma) of the post-collisional granites in the southern Tianshan orogen.

巴楚麻扎山正长岩体形成于286~277 Ma，属于晚二叠世，与南天山造山带晚二叠世花岗岩(300～260 Ma)相一致。

The syenites have more depleted Sr-Nd isotopic compositions εNd(t =+3.4-+4.3, ISr=0.703 03-0.703 44 and younger Nd model ages (TDM=0.6-0.7 Ga) than the coeval mafic dikes.

样品具有较区内同时代基性岩脉更为亏损的Sr-Nd同位素组成εNd(t=+3.4～+4.3、ISr=0.703 03～0.703 44和更为年轻的Nd模式年龄(TDM=0.6～0.7 Ga)。
