This class of deposits is characterized by the abundance of iron oxide in the ores and the associated intensive regional sodic alteration. They may occur in Proterozoic intracraton or Phanerozoic continental margin volcanic arcs with nearby intrusive complex or evaporite. The spatially and temporally associated intrusive rocks are magnetite-series granitoids. Mineralization mainly occurs in second order echelon structures near the main regional structure.

该类矿床以矿石中含有大量的铁氧化物且伴有很强的区域性钠质蚀变为特征，可以产于元古代克拉通内或新生代大陆边缘岛弧环境，其周围具火成岩或含蒸发盐层，时空上与之有关的侵入岩为磁铁矿系列花岗岩，矿化主要产于近区域主断裂的羽状次级断裂中。

On the basis of kinematic analysis of beam pumping unit,the general dynamics equation in the form of virtual power was applied to analyze the contribution of every part including balancing weight of a beam pumping unit to crank axle torque in consideration of inertia effects. The exact analytical expression for computing crank axle torque was obtained.
