成矿时代

本文在K-Ar法测年的基础上，采用了石英40Ar/39Ar法研究白云金矿床的成矿时代，样品从460℃到1600℃进行了九个阶段的加热分析。

Based on the studies of K Ar dating , 40 Ar / 39 Ar technique for quartz sample is chosen to study mineralization age . Nine step heating analyses were made from 460 ℃ to 1600 ℃ .

本区银矿成矿时代为195～100Ma；

The metallogenetic epoch of the silver deposits in Yanshan area ranges from 195 to 100 Ma .

成矿时代为早侏罗世（186±2Ma），矿床属于矽卡岩型成因。

The metallogenesis epoch is the Lower Jurassic ( 186 ± 2Ma ) and the origin of the deposite is skarn .

成矿时代可能为燕山晚期[成矿期绢云母KAr年龄为（10197±249）Ma]

The mineralization period is probably at the Yanshan late stage [ K Ar ages of sericite in mineralization time is ( 101 97 ± 2 49 Ma ) ] .

这三个典型矿床在成因类型、元素组合和成矿时代等方面存在明显差异，可划分出Cu-Mo、Fe-Cu、Pb-Zn、Au-Ag等多个成矿元素组合。

The three typical deposits are significantly different in genesis , element association and mineralization times , and these elements association can be divided into the Cu-Mo , Fe-Cu , Pb-Zn , Au-Ag ore-forming elements and other combinations .

应用Ar-Ar精确测年技术手段厘定了中甸岛弧侵入岩的时空分布关系，了解了不同构造体系构造-岩石组合分布与演化序列，研究了成岩成矿时代及成矿作用过程。

Use the Ar-Ar accuracy dating technology to determine the Zhongdian island arc intrusive rocks in the relationship between spatial and temporal distribution , understanded the different tectonic system structure-distribution and evolution of rock sequences , studied the diagenetic ore-forming epoch and the mineralization process .

在时间上，寒山金矿的成矿时代为339±10Ma，与寒山辉长岩同属华力西期，而且成岩时代早于成矿时代，因此推测寒山辉长岩可能为寒山金矿提供了热源。

The ore-forming age of the deposit is 339 ± 10 Ma , being of Hercynian too . The petrogenic age is earlier than the ore-forming age , possibly suggesting that the rock body provided heat for the deposit .
