| 摘 要： | 冀南邯邢地区矽卡岩型铁矿主要产出于燕山期中偏碱性闪长岩-二长岩类与中奥陶统碳酸盐岩地层接触带附近。矿体形态复杂,褶皱是重要的控矿、容矿构造;矿石类型单一,主要矿物为磁铁矿。矿化蚀变具明显的分带现象,其中钠长石化是重要的找矿标志。与成矿有关的岩体往往是多期脉动形成的,早期侵入体在钠长石化过程中提供成矿物质;后期侵入体带来的岩浆热液不仅是成矿物质的载体,所产生的压应力和热能也成为成矿流体运移的驱动力。在分析此成矿过程的基础上建立了该区矽卡岩型铁矿床的成矿模式。 |

| Abstract: | In the Handan-Xingtai area, southern Hebei, skarn iron deposits mainly occur along the contact zone between Yanshanian mildly and slightly alkaline diorite-monzonite stocks and Middle Ordovician carbonate rocks. The shape of orebodies is complex, and folds are dominant ore-controlling and host structures. The ore type is monotonous and the main ore mineral is magnetite. The mineralization and alteration show pronounced zoning, and albitization is an important ore-hunting indicator. Plutons related to ore deposits formed by multiple magmatic pulses. The earlier intrusions provided ore-forming material during albitization, while magmatic hydrothermal solutions brought by the later intrusions were the carrier of ore-forming materials, and the compressive stress and heat produced by hydrothermal solutions were dynamic forces for the migration of ore-forming materials. Based on the above-mentioned analysis, an ore-forming model of skarn iron deposits in the area has been constructed. |
