Combined with related rare earth element and trace element geochemistry of Huangshaping granites and ore-bearing skarn, it is concluded in this paper that the age of 154 Ma should represent the metallogenic epoch of the deposit, and that there existed a close relationship between the ore-forming process of the deposit and the granite porphyry, which were both formed during the peak stage of Early Yanshanian large-scale rock-forming and ore-forming activities in South China.

结合黄沙坪岩体及含矿硅卡岩型矿体的稀土及微量元素地球化学特征，得出以下认识：该矿床的成矿年龄在154Ma左右；成矿作用与花岗斑岩关系密切，它们都是华南燕山早期大规模成岩成矿作用高峰期的产物。

The Dabie Mountains are unique among ultrahigh pressure metamorphic terranes in having the most profound post collisional plutonism The Mesozoic shoshonitic and calc alkaline intrusive rocks can be divided into three groups with different isotopic ages, rock assemblages and chemical features Group I consists of late Triassic (~ 210 Ma) mafic monzodiorites It could have been generated by partial melting of enriched subcontinental lithosphere mantle due to slab breakoff Group II consists ma...

第 I组，主要由晚三叠世（约210 Ma）二长闪长岩辉长岩体组成，它可能是在板片断离过程中富集的大陆岩石圈地幔部分熔融的产物；第I I组，由中侏罗世－早白垩世（160～120 Ma）的角闪石英二长岩、黑云母二长花岗岩和正长花岗岩组成，主要是由幔源岩浆的分离结晶与地壳混染共同作用的产物；第II I组，以白垩纪（125～95 Ma）的花岗岩和花岗斑岩为代表，是在热穹窿作用过程中大别杂岩深熔作用和高度演化的产物。

The rock mass of syenite porphyry in the north part of Babaoshan coal mine was demonstrated on its lithologic characters,geologic age and occurence.

从岩体的岩性、时代、产状等方面，论证了八宝山煤矿北部的正长斑岩体为一岩盖，下部找煤前景可观，可在井下实施巷探和定向钻探找煤，以延长矿井寿

Lying southeast of Coqen County in western Tibet and tectonically within Lhasa terrain, the Ri'a copper deposit is a skarn copper deposit related to an adamellite porphyry stock.

藏西地区措勤县日阿铜矿产于拉萨地块内，是一个与二长花岗斑岩岩株有关的矽卡岩型铜矿床。

Formation of augen fabrics is decided by the ductile deference between the porphyroblast and matrix in deformation rock.

长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。

The characteristics of elements shows that magma of fine dioritequartz diorites derived from the enriched mantle or lower crust undergone ocean crust subducting and dehydrating, and was formed and emplaced in the process of crust growth. The magma of dioritic porphyritedacitic porphyries emplaced relatively late, it might derive from upper crust or undergo intensive contamination of crustal materials, and was formed in the proces of crust thining. These characteristics suggest that the geodynamics background of the Jinchanggouliang gold deposit formation is the transition process from compression to extension.

元素地球化学特征显示：细晶闪长岩-石英闪长岩的岩浆源于富集地幔或洋壳俯冲脱水交代的下地壳，地壳增厚过程产生并就位；闪长玢岩-英安斑岩类的岩浆就位相对晚，来源具有上地壳性质或被地壳物质强烈混染，地壳减薄过程形成；这种特征暗示金厂沟梁金矿形成的地球动力学背景是在地壳挤压增厚转化为伸展减薄过程。

There are many lamprophyric and othr magmatic dike groups in the main detachment fault of metamorphic core complexes in Hebei province.

研究河北省变质核杂岩构造时发现：在主拆离滑脱带内，可见成群成组产出的煌斑岩及其他浅成脉岩。
