【摘要】 本文综合论述了金矿中成岩成矿的时差分类:容矿围岩与成矿的时差、侵入岩年龄与成矿年龄的时差、同一矿床不同成矿期和成矿阶段的时差,并对金矿成岩成矿时差的研究现状做了详细的阐述。对于同一金矿床中的时差探讨目前尚未放在一个很重要的高度提出,笔者认为该类型的时差问题在地质研究中也是不可忽视的,尤其是对于多成因金矿的成因研究。更多还原

【Abstract】 The time gap in diagenesis-mineralization for gold deposits is one of important bases,especially in confirming the relationship between gold deposits with lithosomes or host wall rocks.From the eighth decade of last century,many geologists began to know that it’s inadequate,or even wrong,just to judge their relationships based only on the space-connections between the ore-bodies and the lithosomes.Thus,the time gap of gold deposit became important day by day.This paper deals with the classes of the time gap of the gold deposit:the time gap between the mineralization and host wall rocks,between intrusion age and mineralization ages,and the time gap at different periods and stages.The authors also introduce the status quo of the time gap study.The authors believe that it should not be ignored in the geological studies,especially in the poly-genetic gold deposits.更多还原
