|Abstract:Abstract: There are obvious aeromagnetic and gravity anomalies in Qihe-Yucheng deep coverage area of Dezhou City, Shandong Province. In recent years, the geological exploration units have made a comprehensive study of the geophysical anomalies in the area, and it is showed that this area has good ore-forming geological conditions of skarn-type iron ore. With the systematic anomaly verification, several skarn-type iron deposits have been exposed in the deep part of the study area, which has made a great breakthrough in the prospecting work and made great progresses in scientific research. The purpose of this paper is to make metallogenic prediction through comprehensive analysis of the results of exploration and research in the area, so as to guide the exploration work of skarn-type iron ore in the future. The exploration work shows that the iron ore bodies in the study area are generally characterized combined ore-controlling by "strata, intrusive rocks and structures", that is, the iron ore bodies occur in the Ordovician (Carboniferous, Permian) strata, the diorite bodies in the late Yanshanian, in the near contact zone between Ordovician (Carboniferous, Permian) strata and intrusive rock bodies. The paper established the comprehensive ore prospecting prediction model of skarn-type iron ore in the study area, based on the analysis of the key ore-controlling factors such as ore-bearing strata, ore-forming geological bodies and ore-controlling structures, and the correlation among the gravity, magnetic anomalies and iron ore bodies. Based on the comprehensive analysis of the geological and mineral characteristics, gravity field characteristics and magnetic field characteristics of the area, the metallogenic prediction work is carried out, and this study delineates three I degree iron ore prospecting target areas of Litun, Pandian and Dazhang and Xueguantun Ⅲ degree iron ore prospecting target area. At the same time, this paper further delineated 6 minimum prediction areas, including western Lilou, Shizhuang, Guodian village, southeast Dingsi, Dazhang village, southern Zhuzhuang minimum prediction areas. This metallogenic prediction research work points out the direction for the prospecting of skarn-type iron ore in the future.
