摘　　要：对含金的辉银矿样品在中性、碱性和酸性氨基酸热液中的活化、迁移与沉积作用，分别进行了实验研究。结果表明，含有酸性氨基酸的热水溶液，比仅含ＮａＣｌ的热卤水、碱性氨基酸和中性氨基酸的热水溶液，更有利于银和金的活化、迁移；银与金和各类氨基酸形成的易溶配位化合物的稳定性不仅和金属、氨基酸的种类有关，而且还受到温度的强烈影响。The experimental studies on the activation,migration and deposition of goldbearing argentite sample in hydrothermal solution containing neutral,alkaline and acidic amino acids are made respectively in this paper.The result shows that the activation and migration of silver and gold in the hydrothermal solution containing acidic amino acids are more favourable than those only containing NaCl,neutral amino acids or alkaline amino acids.It also shows that the stability of dissoluble coordination compounds formed by amino acids with silver and gold is not only related to the types of metals and amino acids ,but also affected obviously by temperature.
