鲁西苍峄铁矿带构造控矿特征浅析

Analysis on Structural Orecontrolling Characteristics of Cangyi Iron Ore Belt in Luxi Area

摘要:

鲁西苍峄铁矿带是山东省典型的“鞍山式”铁矿带之一，区内先后发现和评价了多个大中型铁矿床，但对成矿带控矿因素缺乏系统的研究。该文通过对重点矿床的剖析，阐述了区内断裂构造和褶皱构造对铁矿层的控制规律，研究表明：区内构造形式主要表现为一系列复式向斜和复式背斜，具有相间出现、平行产出的特征，对区内铁矿层的展布起控制作用。

Abstract:

LuxiCangyi iron ore belt is a typical "Anshan type" iron ore metallogenic region in Shandong province. Many large and mediumsized iron ore deposits have been found in this area. But systemic research on metallogenic and ore controlling factors has not been carried out. Based on the analysis of key deposits, the controlling regularity of the fault and fold to iron ore bodies in this region has been introduced. It is showed that main structures represent as a series of duplicate syncline and duplex anticline with the characteristics of alternating occurrence and parallel output. It will control the distribution of iron ore bodies in the region.
