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 Permian dike rock is great development at Kuruktag Region, their rock association is diabase-tjositeplagiophyrite-granite-porphyry, among them, diabse is the most main rock type.

库鲁克塔格地区二叠纪脉岩群非常发育，主要岩石类型是辉绿岩，并有少量的斜闪煌斑岩、斜长玢岩和花岗斑岩。

The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.

岩墙群的SiO2含量为50.22~61.10%，属于基性和中基性岩类，以基性为主；它们的A12O3含量普遍高于15%，属高铝玄武岩类；具有较低的镁指数（Mg#=42.77~62.28）及TiO2含量（0.97~2.41%），说明它们经历了镁铁质矿物的结晶分异作用，也指示它们不是由原始玄武岩浆结晶；Na2O/K2O都大于1，显示出低钾的特点；岩石化学判别，岩墙群岩石属亚碱性系列。

The analysis of lamprophyrespetrology chemistry reveals that it is a series of high potassium- potassium dike rock,it is abandunt in alkali(K2O,Na2O)and has a large reducing capacity.The diagrams of the major-element variation shows that the geochemical compositions-variations of the major oxides have vague general rules of homologous magmatic fractional-crystallization.the pearce diagram of trace elements shows it intensively enriched in LILE,intensively depleted in coherence elements(such as CrNi.et al).

煌斑岩的岩石化学分析表明，乳山地区与金矿成矿相伴生的煌斑岩为高钾质-钾质的碱性脉岩系，富碱(K_2O、Na_2O)，具较强的还原能力(FeO含量均远高于Fe_2O_3含量)，在哈克图解上，主要氧化物的变异规律表现出岩浆分离结晶演化的特点；微量元素的Pearce图呈现强烈的富集LILE，强烈亏损过渡族元素，稀土元素呈向右倾斜的轻稀土富集配分模式，在有关源区性质判别的图解(Cr-Ce／Sr图解和Ce／Yb-Ta／Yb比值图解)上均显示富集地幔源区的性质。
