斑岩

This paper presents petrological and geochemical data of Au-mineralization-related alkali-rich porphyries in the Beiya gold deposit and its adjacent regions, western Yunnan.

提供了与滇西北衙大型金矿床密切相关的富碱斑岩的主量元素及稀土和微量元素的分析数据，对富碱斑岩的成因、起源条件和源区类型进行了讨论。

We consider that there is geochemical anomaly pattern of typical porphyry copper deposit in the Qulong area,through systematic exploration of geochemistry in the mineral district with the geological and structural data. The degradation level of orebody is very shallow. The Qulong area is a good prospect to looking for supper large-scale copper-molybdenum deposit with the porphyritic type Cu-Mo mineralization as its main ingredient.

通过测区系统的地球化学勘查工作，结合地质构造资料，认为驱龙地区存在典型的斑岩铜矿床地球化学异常模式，矿化体剥蚀程度很浅，是找寻以斑岩型Cu-Mo矿化为主的超大型铜钼矿床的良好远景区。

Fluorites formed in uranium mineralization period in the Zoujiashan and Shazhou uranium deposits have ε〓 values from -6.7 to -8.3 and I〓 values from 0.7145 to 0.7204, similar to their host rocks (porphyroblastic lava and sub-granodioritic porphyry) which have ε〓 values from -6.2 to -9.4 and I〓 values from 0.7121～0.7192. On diagram of ε〓- t, the fluorites and host rocks plot in similar area within the evolution field of the basement rocks at Xiangshan. The lead isotopic compositions of pyrites formed in uranium mineralization period plot as a line on diagram of 〓Pb/〓Pb vs.〓Pb/〓Pb. The host rocks plot at the lower value end. Calculation based on the slope of the line and the mineralzation age yields age of 144Ma for the geological body which provided uranium for the mineralization.

邹家山和沙洲铀矿床成矿期萤石的ε〓值(-6.7～-8.3)和I〓值(0.7145～0.7204)与赋矿围岩(碎斑熔岩及次花岗闪长斑岩)的ε〓值(-6.2～-9.4)和I〓值(0.7121～0.7192)相似，在ε〓-t图上，成矿期萤石数据点的投影范围与赋矿围岩的基本吻合，且均落在相山元古宙基底演化域范围内；成矿期黄铁矿的铅同位素组成在〓Pb/〓Pb-〓Pb/〓Pb关系图上呈线性分布，而火山岩的铅同位素组成位于此相关线的低值一端；利用异常铅线的斜率及成矿年龄计算出富铀地质体的形成年龄为144Ma，这与赋矿围岩的成岩年龄(135～140Ma)非常接近。

The deposit has yielded a 187Re-187Os isochron age of (15.32±0.79) Ma, which is identical to the age (14 Ma±) of porphyry copper mineralization in the east Gangdese belt.

年龄数据与冈底斯成矿带东段南侧斑岩铜矿化带的矿化时间(14 Ma左右)具有一致性，表明北矿带的成矿作用与斑岩有关。

The Maotang and Putang gold deposits hosted by granitic porphyries and explosive brecciapipes are genetically related to boilling, explosion and dilution of fluid.

The Xiaoxinancha copper-gold deposit occurs in the upwarped zone rimming the Mesozoic volcanic basin, being of porphyry type; the Naozhi gold deposit occurs in the lifted block within the Mesozoic volcanic basin, belonging to porphyry epithermal transitional type; the Wufeng and the Ciweigou gold deposit, which are two epithermal deposits, exist in the fault zone within the Mesozoic volcanic basin.

小西南岔金铜矿床产于中生代火山岩盆地边缘的隆起带，属于斑岩型矿床；闹枝金矿床产于中生代火山岩盆地内的断隆块，属于斑岩-浅成热液过渡型矿床；五凤和刺猬沟金矿床产于中生代火山岩盆地内断裂带，属于浅成热液型矿床。

The Tinggong porphyry copper deposit is an important deposit in Gangdese PCD belt.

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。
