摘要
利用准流动热液反应装置，进行了草酸与沉积地层中的Ｆｅ、Ｃｕ、Ｐｂ、Ｚｎ元素活化淋滤的成矿模拟实验，结果表明，草酸对地层中的金属元素有较强的活化萃取能力，最大淋滤量对应温度在１２５－１５０℃之间，通过对比实验液相和固相中金属量的变化、配合物稳定常数及实验淋滤率顺序，并结合曲仁盆地成矿特征。
The metallogenic simulated experiments of the activation leaching of Fe, Cu,Pb, Zn in the sedimentary strata by oxalic acid have been studied using quasi-flowing hydrothermal reaction equipment. The results show that the oxalic acid has a strong ability to activate and to extract the metal elements in the strata and the best leaching temperature range is from 125℃ to 150℃. Based on the metal contents in liquid and solid phase, complex stability constant and the leaching sequence combined with metallogenic feature in Quren basin, it is suggested that the ore-forming elements exist mainly in organic complex. And the results show that the organism may play an important role in the formation of the superlarge lead-zinc deposit in Fankou, Guangdong Province.
