The authors dated the zircons from the mineralized porphyritic granite and quartz_monzonite porphyry in this deposit by using the LA-ICP-MS U-Pb dating method. The results show that the two ore_bearing intrusions were emplaced in Middle Devonian and Early Permian, respectively.
文章以近年发现的玉勒肯哈腊苏铜矿床为主要研究对象,对矿区内铜矿化的斑状花岗岩和石英二长斑岩进行了锆石U_Pb法精确定年。

The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.
Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论:(1)赤路钼矿的矿化模式年龄为105.6Ma,与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近,表明二者在成因上密切相关,同属燕山晚期岩浆演化的产物;(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低,低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点,表明其为成矿物质来源于地壳深部,且为斑岩型钼矿床。

Petrochemistry, trace element, REE and isotope geochemistry of quartz syenite porphyry, quartz diorite porphyry, rhyolite, and biotite granite indicate that they belong to series Ⅱ granite defined by Wangliankui (l972), but they have some characteristics of series Igranite, which shows adding of recycle upper-crust materials.
岩浆岩岩石化学、微量元素、稀土元素及同位素地球化学特征表明,莲花山矿区的石英正长斑岩、石英闪长玢岩、流纹岩和黑云母花岗岩属于王联魁(1972)所划分的系列Ⅱ花岗岩(相当于Ⅰ型磁铁矿系列花岗岩),但也具有系列Ⅰ花岗岩的某些地球化学特征,表明岩浆中有再循环上地壳物质的加入。

Based on factor analysis of majior ore-forming elements in the Chengmenshan copper deposit,the authors believe that orebodies related to granite show a Cu-Ag correlation structural model while those related to quartz porphyry display both a Cu-Ag and a Zn-Ag correlation structural model. Mineralization has a multi-period and multistage nature.
本文通过对城门山铜矿床主要成矿元素的因子分析,认为与花岗岩成矿作用有关的矿体具有cu-Ag关联结构模式,与石英斑岩成矿作用有关的矿体除有Cu-Ag关联结构,尚存在有Zn-Ag关联结构模式,成矿作用具有多期多阶段性。
