闪长花斑岩

The formation of silver-gold deposits and copper-molybdenum deposits have relation to quartz diorite and granite porphyry respectively.

区内银金矿的形成与石英闪长岩有关，而铜钼矿的成矿作用与花岗斑岩有关。

The age of individual analysis for zircon from the diorite unit ranges from (137±2) Ma to (1 58 士2) Ma, with a weighted average of (147.7±2.0) Ma, whereas that of the monzonitic porphyry ranges from (115±2) Ma to (164±3) Ma, with a weighted average of (144.5±8.9) Ma.

其中的闪长岩单元年龄为(137±2)~(158±2)Ma，加权平均年龄为(147.7±2.0)Ma，二长花岗斑岩为(115±2)~(164±3)Ma，加权平均为(144.5±8.9)Ma。

The main rock types include porphyritic granodiorite, porphyritic granite, biotite adamellite and garnet-granitite.

岩石类型主要有斑状花岗闪长岩、巨斑黑云母花岗岩、黑云二长花岗岩、含石榴石花岗岩等。

Mo ore bodies are divided into quartz porphyry fissure, granodioritic fissure and cataclastic alteration zone quartz vein types according to surrounding rock properties and structural location.

钼矿体依其围岩岩性和构造位置的不同可以分为石英斑岩裂隙型、花岗闪长岩裂隙型和破碎蚀变带石英脉型。

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 sulfur and lead isotope compositions indicate that the ore_forming materials were mainly derived from the volcanic rocks and granodioritic porphyries.
