一、矿床一般特点我国菱铁矿床在区域上分布很广,时代上从元古代到第三纪皆有成矿。本文仅以华北、华南分布在古生界中的几个代表性矿区为例。初步探讨其成矿地球化学特征。寒武—奥陶系中的菱铁矿床主要分布在华北地区,山东淄河式层控铁矿是其中具有相当规模的菱铁矿床。矿床位于鲁中隆起的边缘,适处沂沭裂谷西侧,构造和岩浆活动比较发
First, the general characteristics of the deposits Siderite deposits in our country is widely distributed in the area, the era from the Proterozoic to Tertiary Jieyou mineralization. In this paper, only the North China and South China distributed in Paleozoic in several representative mining area as an example. Preliminary discussion of its metallogenic geochemical characteristics. The Cambrian-Ordovician siderite deposits are mainly distributed in North China. Shandong Zihe-type stratabound iron ore deposit is a siderite with a considerable scale. The deposit is located on the edge of the Luzhong uplift, which is located west of the Yi-Shu rift and has relatively high tectonic and magmatic activity
