摘　　要：黑色岩系中的矿产，早已为人们所瞩目，我省中元古宙老岭群珍珠门下亚组碳质板岩中有机碳质量分数达35.00%～1.17%，平均10.14%。其中金、铜、钴背景高，平均值分别为：0.148×10-6,52.94×10-6,8.46×10-6,是中国东部山区平均值123、43、78、倍。是这些元素的明显矿源层。在通化大顶子珍珠门下亚组黑色岩系形成一处铜钴小型矿床，其中含有金矿扁豆体，平均品位52.8×10-6，是一处颇有远景的含金铜钴矿床。The minerals in the black rock series have attracted the attention of people. Organic carbon mass fraction are 35%~1.17%, with an average of 10.14%, in carbonaceous slate of Mesoproterozoic erathem Laoling group Zhenzhumen low subformation of Jilin Province. The background value of gold, copper, cobalt is high, average value is 0.148×10-6,52.94× 10-6,8.46× 10-6 respectively, and is 123, 43, 78 times in the mountains of the eastern China average values respectively. The black rock series is the obvious ore source bed of these elements. A copper cobalt deposits of small size is found in the black rock series of Zhenzhumen low subformation of Tonghua Dadingzi. The copper cobalt deposits contain the gold lens, the gold of average grade is 52.8 × 10-6, and it is quite a potential auriferous copper cobalt deposit.
