铁矿床形成在漫长的地质年代,多数埋藏于地表以下,要找矿就得了解和掌握矿床成因及其地质特征与分布规律。以往的矿床地质学,对沉积岩、变质岩和侵入岩的成矿找矿问题,有不少论述,但对曾在地质史上起过巨大变革作用的火山活动及其成矿作用,几乎从无论述,以至在地质学界形成了一种“火山岩中无大矿”的框框。我国火山岩的分布十分广泛,长期被排斥在找矿范围之外。在辩证唯物论的指导下,我们终于冲破了旧理论的束缚,在梅山火山岩地区找到了大型富铁矿。目前,我国各地火山岩型铁矿正在不断发现,昔日找 The formation of iron deposits in the long geological era, most buried below the surface, to find the ore to understand and master the genesis and geological characteristics and distribution of the law. There are many expositions on the mineralization of sedimentary rocks, metamorphic rocks and intrusive rocks in the previous deposit geology. However, volcanic activities and their metallogenic activities, which have played a tremendous transformation in geological history, , As well as in the geological community has formed a “large volcanic ore mines” box. The distribution of volcanic rocks in our country is very wide and has long been excluded from prospecting. Under the guidance of dialectical materialism, we finally broke through the shackles of the old theory and found a large iron-rich ore in the Meishan volcanic region. At present, volcanic iron-type iron ore in various parts of China is constantly being discovered and found in the past
