The intermediate-basic volcanic rocks with SiO2 content less than 57.48 wt% are high in Al2O3(20.22-16.34 wt%) and K2O, enriched in large ion lithophile elements, show obvious Nb, Ta negative anomaly, these are same to the basalts which formed in island arc. The andesite, dacite and rhyolite rocks with SiO2 content between 62.11-75.19 wt%, are similar with the I-type granitic rocks formed in island arc in their geochemistry. It is suggested that the Jueluotage area of East Tianshan was in island arc setting during Late Carboniferous, when the subduction of the ancient Asian Ocean was in progress.
其中w(SiO2)小于57.48%的中基性火山岩具有高w(Al2O3)(16.34%~20.22%)，较富钾，富集大离子亲石元素，具明显的Nb、Ta负异常；w(SiO2)介于62.11%~75.19%之间的安山岩、英安岩和流纹岩岩石化学特征与准铝质的Ⅰ型花岗质岩石相似，其地球化学特征也反映出岛弧花岗岩的特点，表明东天山觉罗塔格地区路白山一带在晚石炭世仍处于古亚洲洋向南俯冲的岛弧环境。

The formation process of the rocks is divided for thefirst time into three cycles corresponding to J2, J3, and K1, respectively, and each cycle into early,middle, and late periods based on intruding contact relationship among different types ofgranitoids.3. A detailed study on the petrological characteristics of different cycles of theMesozoic granitoids supports classification of the rocks into three lithological associationsincluding A-type, high-K calc-alkaline, and calc-alkaline granitoids, of which the first associationbelongs to alkaline series, and the others belong to calc-alkaline series. It is shown that thelithologies change from diorite, quartz monzonite, and granodiorite to monzonitic graniteand syenogranite with periods from early to late in each cycle.4. A preliminary summarization hasbeen made on the evolution characteristics of the rocks.
首次将中生代花岗岩类划分为J2旋回、J3旋回、K1旋回等三个旋回，并依据不同岩石类型间的侵入接触关系，将每个旋回又划分为早、中、晚三期。3、在详细研究区内中生代不同时期花岗岩类岩石特征的基础上，首次将区内中生代花岗岩类划分为碱性系列碱质A型花岗岩类以及钙碱性系列高钾钙碱性花岗岩类和钙碱性花岗岩类等二个系列三种岩石组合类型，确定每个旋回从早期到晚期，岩石均具有从闪长岩、花岗闪长岩、石英二长岩-二长花岗岩-正长花岗岩演化的趋势。4、初步总结了区内中生代花岗岩类的演化特征。

The experimental products include crystal phase quartz, feldspar (alkila-feldspar, albite, K-feldspar), zinnwaldite and topaz, a melt phase and a trace vapour. The solid products were been studied by optics method, electron microprobe and X-ray analysis. The results show that liquidus temperature raises slightly and solidus temperature falls down obviously and that the upper temperature limit raises for the stability field of quartz and topaz, and falls down for the stability field of alkila-feldspar as F contents in crease.

The petrological study and studies in element and isotopic geochemistry indicate that the pluton belongs to high-potassium calc-alkaline I-type granite, whose magma came from basic basalt in the thicken crust bottom by partial melting, and are of syn-collisional features. The pluton provides a direct petrological evidence of the plate collision and amalgalation.
