| 摘 要： | 区域深断裂带（即昆南深断裂）控制着华力西期超基性岩和印支期花岗岩的分布。由于花岗岩的成矿作用，并在构造及岩性圈闭条件下，形成了德尔尼黄铁矿型铜钴矿床。上石炭统的下部片岩组含矿性较好，是区内矿源层之一，但矿质主要来自花岗岩岩浆热液。该矿区属浅成热液矿床

| Abstract: | The Deerni pyrite type copper/cobalt deposit owes its genesis to the Indo Sinian granite associated with the deep faulting of Kunnan megafracture as well as to the controls of sturcture and lithology. The granite acted as a key source bed though part of ore forming materials could be tapped from the lower schist of the late Carboniferous sequence. In view of its metallogenetic type, the deposit should be listed into a epithermal category. |
