菱铁矿是铁矿中的重要矿床类型之一,其中沉积与沉积变质菱铁矿床又占一定比重,因此,用化探方法寻找这类矿床,具有现实意义.过去已有一些单位开展了此项工作,取得了一定效果.本着总结提高的原则,我们曾就这类矿床的指示元素及其地球化学特征,进行了一些初步研究.下面谈谈我的粗浅认识. Siderite is one of the most important types of iron deposits, of which sedimentary and sedimentary metamorphic siderite accounts for a certain proportion, so it is of practical significance to search for such deposits by the method of geochemical prospecting This work has achieved some results.According to the principle of summarizing and improving, we have conducted some preliminary studies on the indicator elements and their geochemical characteristics of such deposits, and here I will talk about my superficial understanding.
