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 The grain size and morphology of 79 gold and 3 gold samples in Heilongjiang Province were studied. The average particle size of most samples was between 03 ~ 06mm, with the normal distribution as the main factor. The sorting coefficient and rounding degree indicated that most of the samples were gold particles transported by long distance. Through the comparison of the overall morphology of gold grains, the morphology is divided into four types, of which the first is rock gold and the second is the residual gold which is beneficial to find the native gold deposit in its vicinity
