摘要
“临界成矿地质条件”系指具有“临界性质”的成矿地质条件。沉积或受变质沉积矿床的临界成矿地质条件主要是古地理和水动力条件 ;内生矿床的临界成矿地质条件主要是构造条件 ;石油的生油和贮油条件所表现出的临界性质十分明显 ;风化矿床的临界成矿地质条件主要是水文地质条件、构造条件。临界成矿地质条件应该是各类矿床都具备的 ,但在不同矿床中的表现形式不同。深入研究临界成矿地质条件可以促进矿床学的进展 ,达到定量化的境地 ,同时成矿预测不应只是简单地据其某些大致相似的条件去类比、预测 ,而要努力寻找并发现最关键的具有临界性质的成矿地质条件 ,这样才不致使预测工作陷于盲目。
Critical mieralizing conditions” refer to those with critical character. They are paleogeographic and hydrodynamic conditions for sedimentary and sedimentometamorphic deposits, structural conditions for endogenetic deposits, hydrogeological and structural conditions for weathered deposits, and oil producing and storaging conditions for oil fields. No types of deposit would not possess critical mineralizing conditions but the latter would behave differently depending on deposit type. Thoroughly probing into critical mineralizing conditions can promote study of mineral deposits, thereby reaching their quantitative forecasting. At the same time, the forecasting, before not blindly, is not confined to comparison of similar aspects between deposits but to striving for environmental factors which are the key to, or critical for, mineralization
