长江中下游地区是我国重要的铁矿基地.这里的夕卡岩型和玢岩型铁矿的地质研究程度较高,矿山生产揭露的地质矿化现象日新月异.作者在学习前人成果的基础上,对上述两类矿床进行过较长时间的观察研究和综合对比.我们认为本区的两类主要铁矿类型——夕卡岩型铁矿和玢岩铁矿成因上近似,都包含有接触交代成矿作用、碱质交代成矿作用、矿浆贯人作用和沉积—接触变质成矿作用以及相应的矿床成因类型.在此基础上,本文分析了成矿的区域构造和岩浆活
The middle and lower reaches of the Yangtze River is an important iron ore base in China, where the skarn-type and pluton-type iron mines have a high degree of geological research and the geological mineralization revealed by mine production changes rapidly with each passing day.Based on the study of previous achievements , We have observed and studied the above two types of ore deposits for a relatively long period of time and we believe that the two types of major iron ore types in this area, namely, the skarn type iron ore and the iron rock ore rock, are all genetically similar and contain contact Metallization, metasomatization, mineralization and sedimentary-metamorphic mineralization and corresponding genesis types of ore deposits are analyzed.On this basis, the paper analyzes the regional structure and magmatic activity of mineralization
