| 摘 要： | 对黑龙江省７９个砂金及３个岩金样品进行了粒度及形态研究，多数样品的平均粒径在０．３￣０．６ｍｍ之间，以正态分布为主，分选系数和磨圆度表明多为远距离搬运的砂金，通过金粒总体形态比较，将形态划分为４类，其中第一类为岩金，第二类为有利于在其附近寻找原生金矿床的残积金。

| Abstract: | The shapes and sizes of 19 placer gold and 3 rock gold samples in Heilongjiang have been studied. The mean grain size of most samples is from 0 3 to 0 6 mm and mainly occurs as normal distribution. The sorting coefficient and the psephicity indicate that most of the placer gold were transported for a long distance. By comparing the general shapes of gold grains. They may be divided into four types. The first type is lode gold and the second is residual gold farourable for finding primary gold deposit nearby. |
