| 摘 要： | 乌拉嘎金矿床的黄铁矿和白铁矿均可划分为三个世代,不同世代的黄铁矿与白铁矿在形态、成分和热电性上表现了不同的特点,与金矿化有不同的联系。形态上,粉末状和球粒状黄铁矿以及胶状白铁矿与金矿化关系密切;成分上,富硫贫铁和As/Sb值高的黄铁矿、白铁矿对金的富集有利,它们的热电系数值与矿石品位呈正相关。

| Abstract: | The pyritc and marcasitc can be divcdcd into three cpochcs in the gold deposit of Wulaga. The shapes, compositions and thcrmo clcctricifics of pyritc and marcasitc show different characteristics , and have different relationship with gold ore-forming process in different epoch. As for the shape,powdered and ballbraincd pyritc and marcasitc have closed relationship with gold ore forming process,compositionally,rich-S,low-Fc and higher value of As/Sb in pyritc and marcasitc contribute to gold mincrogcncsis. The values of thcrmo clcctrictity in pyritc and marcasitc arc positive with orc grade. |
