| 摘 要： | 依据岩石密度特征，应用布格重力异常资料，在内蒙古东部地区推断7个大型岩浆岩活动区（带）。这些岩浆岩活动区（带）控制着内蒙古自治区东部地区大部分内生矿床，也就是说每一个大型岩浆岩活动区（带）实际上是一个成矿系统。因此，应用布格重力异常资料可以推断岩浆岩活动区（带），预测内生矿床，筛选化探异常。

| Abstract: | Seven large areas(zones) of magmatic activities were detected on the basis of rock density characteristics and Bouguer gravity anomaly data of eastern Inner Mongolia.In this region,most endogenetic deposits are controlled by these large magmatic activity areas(zones),and a large magmatic activity area(zone) constitutes a metallogenic system.Therefore,regional geochemical anomalies can be ranked and endogenetic deposits can be forecasted on the basis of Bouguer gravity anomaly data. |

| Keywords: | magmatic activity area(zone) metallogenic system characteristics of gravity field |
