安林地区接触交代型铁矿成矿规律探讨

Approaches to the Regularity of FormingContact - metasomatic Iron Deposit in AnyangCounty and Linxian County

产于中酸性岩浆岩与碳酸盐岩接触带的接触交代型铁矿,受地质构造条件的控制,在安林地区形成了两条成矿带,包含8个矿田。在有利成矿的地质构造和岩浆岩的复合部位,形成了矿石储量最大的李珍矿床。根据物探异常显示,安林地区仍具找矿前景。

The contact - metasomatic iron deposit, which emerges between intermediate - acid magmatic rock and carbonate rock, is controlled by geologic structure. Therefor it forms two pieces of metoallogenic belt in Anyang County - Linx-ian County, including eight ore fields. The composite region of geologic structure and magmatic rock, which has the advantage of making of metoallogentic belt, has formed lizhen deposit of the first mineral reserves. According to geoplysical prospecting evidences abnormity, this region still have prospects of mining.
