冯家峪铁矿区铁矿成矿规律及找矿方向研究

研究表明，冯家峪铁矿矿区内构造可分为褶皱构造控矿模式以及褶皱构造和韧脆性剪切断裂复合构造的控矿模式。一期褶皱控制铁矿的整体分布,控制矿体的规模。二期褶皱使矿体形态复杂化；褶皱构造与韧脆性断裂复合控矿作用主要表现为:剪切作用使矿体在区域上的分布强烈定向；剪切作用过程中形成的牵引褶皱,也使矿体再次的富集。据此认识，在麻子坑采区外围通过钻探工程获得了工业矿体，使找矿工作取得了突破。

Study on the Law of Mineralization and Prospecting Direction in Fengjiayu Iron Ore Area

Studies show that the ore-controlling modes in Fengjiayu iron ore area include fold texture and ductile-brittle shear fracture composite texture types.The first period folds have controlled the overall distribution and size of orebodies while the second period folds have made the orebody morphology more complex.The composite ore-controlling by folds and ductile-brittle fracture mainly exhibits as such that the shearing has made the orebody regional distribution strongly oriented and the drag folds formed in the shearing process have re-enriched the orebodies.According to this knowledge, industrial orebodies were found by the drilling engineering around Mazikeng mining area, a breakthrough in ore prospecting.
