矿源层

冀东高级变质岩区金矿矿源层分析

Analysis on gold source bed in the high grade metamorphic zone in the eastern Hebei Province

由于黔西南普遍存在着玄武岩喷发对地层中汞金含量在时间上和空间上的直接和间接控制作用，使地层中的汞、金含量达到了初始富集，即形成了矿源层。

Because of the control over the mercury and gold contents in strata by the basaltic exhalation existed widely in southwestern Guizhou directly and indirectly in time and space , the original enrichment of mercury and gold elements in strata of this ore zone source bed was formed .

深海沉积的凝缩段是Zn及部分pb的矿源层；

The condensed sequence of deep sea sediments is the major source bed of Pb and Zn .

第Ⅲ、Ⅳ旋回玄武岩系（P（2β3）和P（2h））是区内重要的矿源层和赋矿层位。

The basaltic formation of the third and fourth cycle ( P2 β 3 and P2h ) is the important ore Source and ore bed in this district .

金的成矿作用及金矿床的形成，通常与含金丰度相对较高的地台构造层有密切的成因联系，它们提供了重要的物质来源，可认为是矿源层（Sourcebeds）。

Gold metallogenesis and the formation of gold deposits usually have close relationship with the platform strata with relatively high gold abundance . These strata are considered ore-forming material source beds .

地层中Au的丰度值为克拉克值的2～3倍，是形成金矿的矿源层。

The Au abundance in stratum is more 2 or 3 times than Au clarke , thus the Tahua Group is an ore source bed .

成矿流体是具有δCe和δEu负异常的酸性溶液，基本保留了矿源层的稀土分布模式。

The ore fluid was an acidic solution characterized by δ Ce and δ Eu negative anomalies and it basically maintains the REE patterns of the original source bed .

寒武纪地层的W、Sn等元素含量较高，是重要的矿源层。后期的热事件使成矿元素发生重新分布。

Precambrian strata which are rich in ore-forming elements such as W and Sn are resource layer of the tin poly-metallic deposit and the geothermal incidents afterwards made these elements redistribute .
