摘要
采取龙水金矿合矿层位岩石，并均匀参入含金溶液，使试验样品含金量达150g／t。在万能材料实验机上进行72h的高温高压试验（温度恒定：450℃，最大压力达：1400kg／cm2）。结果表明，金发生了活化转移和沉淀富集，其规律可与金矿的成矿作用类比。龙水金矿今后的找矿方向仍然是龙水一三郎冲大断裂及其附近围岩中。
Some rock samples of the ore-bearing bed have been collected in the Longshui GoldMine, Guangxi. Gold-bearing solution have been added evenly into the samples. Their totalcontents of gold are about 150 g/t. The samples are tested by the all purposes material machine for 72 hours under high pressures and temperatures (at temperature: 450℃, maximumpressure: 1400 kg/cm2 ). The result indicates that the gold has been moved and re-precipitated and re-enriched. The reguarities are very similar to the mineralization processes of gold.The target area of gold exploration is still at the Longshui-Sanlangchong big fault or in thecountry rocks near it in the Longshui Gold Mine.
