Through the contrast analysis on the chemical constitution of the magnetic iron ore and the plagioclaseamphibolite in Nanling ultra poor magnetite, and the analysis of graphs of and (FeO+Fe2O3+TiO2)Al2O3MgO, combining the geological features of mining area and the ore body characteristics, the conclusion can be drawn as follows: the plagioclaseamphibolites including magnetite and the plagioclaseamphibolite in Nanling mining area are formed from the oceanic tholeiite with rich iron after the deteriorating, and their genesis types should be the ultrapoor iron deposit of weathered residual origin.

通过对南岭超贫磁铁矿的磁铁矿石、斜长角闪岩化学成分的对比分析，结合矿区地质特征和矿体特征，对矿体进行n-n和w( FeO+Fe2O3+TiO2)-w(Al2O3)-w 图解分析，结果显示南岭矿区的含磁铁斜长角闪岩和斜长角闪岩是大洋富铁拉斑玄武岩经变质作用而形成的，矿床的成因类型为风化残积型超贫铁矿床。

The variograni of No.100 ore-body in three directions have been calculated, and the variogram curves were formulated. All these curves are leap type.
