变质岩

The muscovite-chlorite geothermometer, muscovite-biotite geothermometer and chlorite compositional geothermometer that are suited to the low-temperature conditions have only been used in the interpretation of regional metamorphism of sedimentary rocks and have never been used for mylonites of ductile shear zones.

适用于低温条件下的白云母-绿泥石地质温度计，白云母-黑云母地质温度计和绿泥石成分温度计仅在区域变质岩中应用过，从未在糜棱岩中使用。

Increase of that clast of sedimentary rock, high-grade metamorphic rock and unstable heavy minerals shows tectonically active setting and obvious uplift of Bogda Mountain during the Late Jur.

新疆博格达地区中—新生界碎屑成分自中侏罗世的中晚期开始发生了巨大变化，主要表现在：自中侏罗世晚期开始，沉积重矿物组合及相对含量发生较大变化，不稳定重矿物、较高级别变质岩岩屑明显增多，显示此时发生的物源属性变化及构造活动的存在；自侏罗系西山窑组沉积晚期开始，砂岩碎屑成分中的沉积岩碎屑明显增加，显示盆缘沉积岩物源的隆升和剥蚀作用。

These results suggest that the diagenesis material of the Xiangshan volcanic intrusive complex was derived from crustal sources. The sources either had relatively lower maturity or had more juvenile mantle-derived igneous rocks than the exposed basement metamorphic rocks. Involvement of a small amount mantle-derived magma during the formation of the Xiangshan volcanic-intrusive complex was also possible. The diorite enclave, sub-quartzmonzonitic porphyry and lamprophyre were probably different mixing products between mantle and crust materals.

上述同位素示踪结果充分证实：相山火山-侵入杂岩的成岩物质主要为壳源，但与该区出露的基底变质岩相比，其物源区的成熟度相对较低或含有一定量的火成物质，并且不排除在其成岩过程中少量地幔物质的介入；闪长质包体、次石英二长斑岩及煌斑岩的成岩物质均含有一定量的地幔组分，可能为壳-幔混合作用的产物，只是受地壳物质混染的程度不同而已。

The metamorphic rocks of the area consist of granulite, plagioclase-gneis, biotite leptite and various kinds of schists of granulite to amphibolite facies By reconstruction, this metamorphic series is composed of three original formations which inciude five originai rock types: intermediate-acid volcanics formation at the bottom basic-felsic bimodae volcanits formation in the middle and basic-andesitic-felsic volcanics formation at the top...

区内太古代变质岩系广泛发育，其下部为深变质的麻粒岩相地层，上部为中深变质的角闪岩相地层，后者产出红透山式铜锌矿床多处，以及张胡子沟铜矿床和大荒沟硫铁矿床等一系列块状硫化物矿床(图1)。矿石中铅同位素年令为25～26亿年，在形成时代上可以和鞍本地区鞍山群对比。
