| 摘 要： | 新鲜的没有发生过任何金流失的岩石Ａｕ／Ｐｄ比值为一常数Ｋ。Ｐｄ与金的地化性状截然不同，在成岩乃至变质作用过程中呈特殊的惰性，保持其原始含量不变。因此，据Ａｕ／Ｐｄ比值（Ｋ）可以推算原岩金的原始含量Ａｕ（原），探求其可成矿率，判定矿源层，指出Ａｕ测定值低、Ｐｄ含量高的岩石是金的可能原始矿源层，可看作金矿找矿的有利地段。 |

| Abstract: | The An/Pd ratio of fresh rocks in which no any gold has been lost is a constant K. Pd,the geochemical behaviour of which is destinct from that of gold, shows particular inertnessin the process of diagenesis and metamorphism, and its initial content remains unchanged. According to An/Pd ratio(K),the initial gold content in original rocks can be calculated to evaluate gold mineralization probability and to locate the source bed. It indicates that the rockwith low measured An value and high Pd content is the primary source bed of gold that canbe considered as a favourable site for gold prospecting. |
