Metallogenic Regularity and Prospecting Model of Skarn Type Iron Deposits in the Central and Northern Parts of Shandong Provinc
摘要
Abstract
Geological conditions for the mineralization of skarn type iron deposits in the central and northern parts of Shandong province are superior.It is an important iron rich deposit base in China.Skarn type iron deposits related to intermediate intrusive rocks developed well.The iron deposits in this area have the char-acteristics of"large ore body scale,high ore grade,and concentrated distribution of deposits".In this pa-per,through sorting out data and conducting on—site investigations,typical iron deposits in this area have been compared and studied,and mineralization laws have been summarized.It is showed that the minerali-zation age of iron deposit in this area is almost consistent.It belongs to early Cretaceous.Iron deposit has diverse ore bearing space.It mainly occurs near the contact zone between diorite bodies and the Ordovician system.Some iron ore bodies are produced in the interlayer unconformities and interlayer slip zones of the Ordovician system and the overlying Carboniferous Permian system.Some small scale iron ore bodies are occasionally seen inside the rock mass,and each iron ore body is connected to each other by fault struc-tures,with obvious zoning characteristics.A prospecting model for exploring skarn type iron deposits in the study area has been constructed.Based on the study of mineralization laws,through extracting deep level information,such as magnetic anomalies,gravity anomalies,electrical anomalies and seismic anoma-lies,it is regarded that ore bearing areas is an effective way to achieve breakthroughs in deep prospecting work.关键词
