根据自然金晶体生长和台阶运动的动力学以及台阶聚并规律 ,自然金的晶体形态和晶面微形貌具有较强规律性。晶体形态随温度和金的过饱和度增高 ,由 { 110 }习性晶经 { 10 0 }习性晶演变为 { 111}习性晶 ;晶面上阶梯状生长纹的高度随金的过饱和度的增大而增高 ,阶梯的密度随热液碱性程度的升高而增大。这一结论得到河南祁雨沟金矿 、 阶段自然金晶体形态的证实 ,并与其它金矿的地质事实和人工合成实验结果相符 ,其对金矿成矿和找矿研究具一定的指导意义。
According to the dynamics of natural gold crystal growth and step motion and the rule of step convergence, the crystal form of natural gold and the micromorphology of crystal face have strong regularity. The morphology of the crystal changes with the temperature and supersaturation of gold, and the {110} habit crystal changes from {110} to {111} habit crystal. The height of the step-like growth pattern on the crystal plane increases with the supersaturation of gold Large and increased, the density of the ladder with the hydrothermal alkaline increased. This conclusion is confirmed by the Qiyuogou gold deposit and the phase natural gold crystal form in Henan Province and is consistent with the geological facts and synthetic results of other gold mines. It is of guiding significance to gold mineralization and ore prospecting.
