Chondrite-normalized REE patterns are right-inclined, and the REE distribution patterns for skarn and ores are similar to those of the Tongguanshan quartz monzodiorite, which indicates that the hydrothermal fluids of the skarn deposit in the study area were mainly derived from dioritic melt.

稀土元素球粒陨石标准化组成模式为右倾型，夕卡岩，矿石的稀土配分曲线类似于铜官山岩体石英二长闪长岩，故认为形成本区的夕卡岩型矿床的热液流体主要来源于闪长质熔体。

Dioritic enclaves were discovered by the authors in thesubvolcanic rock dike of the northern part of the large collapse volcanic basin in Xiangshan, Jiangxi Province. These enclaves have a typical back vein and a quenched margin,and contain a large number of acicular apatites.

在江西相山大型塌陷式火山盆地北部的潜火山岩岩墙中，笔者发现了闪长质的岩石包体，这种包体具典型的反向脉及淬冷边，且淬冷边内含有大量针状磷灰石。

The Zhonggu ore field, as an important orecluster in the southern part of the Ningwu volcanic basin, hosts series of iron deposits which are represented by Gushan and Baixiangshan and usually occurred at the contact zone between the dioritic porphyry and sedimentary rocks.

钟姑矿田作为宁芜盆地南部重要的矿集区，发育一系列以姑山矿浆熔离型和白象山高温气液型为代表的大型玢岩铁矿，这些铁矿均主要产于闪长玢岩岩体和沉积围岩的接触带。

On the Harker diagram, there are general correlations between the oxides and SiO〓 of the Xiangshan complex, whereas the dioritic enclaves are not cosistent with the correlation trend of the complex. On the classification diagram of biotites, the biotites of the complex belong to ferribiotite, while the biotites of the diorite enclaves fall into the area of magnesio-biotite.

在哈克图解中，杂岩体全岩各氧化物与SiO〓之间总体上呈良好的线性关系，但闪长质包体却很不协调；在黑云母分类图解中，杂岩体中的黑云母均落在铁质黑云母分类区，而闪长质包体中的黑云母无一例外地落在镁质黑云母分类区。

A REE partition simulation suggests that the Tianzhushan intermediate rocks can be generated by partial melting, in coupling with fractional crystallization, of dioritic gneiss which is similar in chemical compositions to the mafic rocks in the lower crust in North Dabie; partial melting of intermediate grey gneiss which is similar in chemical compositions to the middle crust in North Dabie can generate the Tianzhushan felsic rocks.

REE配分的定量模拟计算结果表明，与基性下地壳相似的北大别基性闪长质片麻岩部分熔融并经过结晶分异能够形成与天柱山中性岩类似的稀土元素组成，而与中性地壳相似的北大别中性灰色片麻岩部分熔融能够形成与天柱山花岗岩类似的稀土元素组成。

Kubusunan granite is chracterized by low87Sr/86Sr initial values and high ε values, indicating its origin partly from mantle rocks. The number of microgranular dioritic enclaves is the direct evidence for crust-mantle magma mixing, thus showing that enclaves are the residual formed from the partly fusing of basic magma.

库布苏南花岗闪长岩体具有低锶初始比值I和正ε值，表明花岗岩的来源有地幔物质参与，而大量发育的暗色微粒闪长质包体是壳幔岩浆混合作用最直接的证据，微粒包体是基性源岩部分熔融作用形成的残余体。

Most of the Xiangshan volcanic rocks are peraluminous-metaluminous (ASI=1.02～1.16), while subvolcanic rocks are mostly metaluminous (ASI=0.90～1.02), and dioritic enclaves are undersaturation of aluminum.

相山火山岩系的ASI值为1.02～1.16，为准铝—过铝质，次火山岩的ASI值为0.90～1.02，多为准铝质，而闪长质包体的ASI值为0.59～0.71，属铝不饱和类型。

The Huangyangshan pluton is a typical post-collision pluton in the Kalamaili orogen of the Eastern Junggar, many dioritic microgranular enclaves distribute in it.
