Abstract: Laiwu Area is an important producing area of skarn iron deposits in China.The mine rock mass is the main ore-forming rock mass in this area.The Gujiatai Iron Deposit in this area is a large iron deposit found in this area.In recent years, great progress has been made in prospecting in Pandian and Zhangjiawa Areas of Luxi, indicating that there is still great potential for finding rich iron deposits in Shandong Province.Since the 1980 s, the deep prospecting work has not been carried out in the peripheral system of the iron mine.This paper makes a comprehensive analysis of the geological metallogenic conditions and magnetic anomaly characteristics of Gujiatai Iron Mine, and discusses the peripheral and deep prospecting prospects in combination with the prospecting criteria of Laiwu contact metasomatic iron.
