摘　　要：上黑龙江盆地蕴藏着丰富的金矿资源,金矿床(点)分布广泛.通过对金矿床(点)的地质背景、分布特征及微量元素、稳定同位素的研究,认为兴华渡口群、二十二站组砂岩提供了成矿物质,提出了"矿源层-构造-岩浆岩三位一体"成矿及找矿模型,圈定I级成矿预测靶区5处I,I级成矿预测区6处I,II级成矿预测区8处.Gold deposits and occurrences are broadly distributed in the Upper Heilongjiang Basin.Based on the study on the geology,distribution,microelements and stable isotopes of the gold deposits,it is concluded that the sandstone of Xinghuadukou and Ershierzhan groups supplied the ore-forming matters.The metallogenic and prospecting model of source bed-structure-magmatic rock is proposed,by which the potential metallogenic areas are predicted.
