摘　　要：界牌岭矿床的矿体具有独特的不对称分布特征,而原生晕的形态却显示出显著的对称分布特征,这样的不一致性可能预示着存在新的矿体。由于矿体在褶皱的一翼顺层发育,且断层恰好切过褶皱,推测矿体可能被断层错断因而出现了不对称分布。此外,含铍萤石矿完整地保存预示着矿区的剥蚀程度不高,且原生晕及与矿体位置紧密的花岗斑岩向深部继续延伸,推测深部存在花岗岩,也就预示着存在新的围绕花岗岩的矿体。The Jiepailing tin polymetallic metals ore bodies occur in the asymmetric form, which is inconsistent with the symmetric shape outlined by the primary halos. It may indicate the existence of the undiscovered ore bodies.Considering orebodies occur in the limb of the symmetric folds where the fault cut through, therefore, it is supposed that orebodies are displaced downward by the fault and thus it results in the asymmetric distribution. Additionally, the beryllium-bearing fluorite orebody was completedly preserved which it indicated that the erosion level is not high. Considering the primary halos and granite porphyry nearby the orebody extends to the depth, it indicates there probably is hidden orebody around granite porphyry in the depth.
