| 摘 要： | M-15磁异常(东湾异常)是国内外学者关注的寻找铜镍矿的重点预测区之一。该异常处于全覆盖区,前人推断它是由超基性岩体引起的。本次采用重、磁方法和已知白家咀子超基性岩体磁异常特征对比,认为M-15系非同源重磁异常,以磁力高、重力低为组合特征,异常体埋深较大,磁异常可能为1200 m以下的超基性岩引起,重力低异常系埋深1 000 m左右的龙首山群元古界基地凹陷引起。这一结论对于扩大铜镍矿源起到了积极的作用。

| Abstract: | The M-15 magnetic anomaly(Dongwan anomaly) is a key prognostic area for copper and nickel deposits,to which geologists both in China and abroad have paid close attention.As this anomaly lies in a fully covered area,previous researchers considered it to be caused by an ultrabasic body.Using the gravity and magnetic method to compare it with the magnetic anomaly related to the known Baijiazui ultrabasic body,the authors have reached the following conclusions: The M-15 anomaly is a noncognate gravity and magne... |
