Jiaodong area is one of the major gold producing areas in China, and the deep prospecting in this area is to seek deep breakthroughs and blind spots at present. With the gold concentration area in Jincheng Town in Laizhou City and Ershilidian Town in Haiyang City as an example and based on the prediction and assessment theory and method of deep gold resources, this study summarizes the deep spatial characteristics and relationships of the Archaeozoic-Mesozoic intrusive rocks, Precambrian metamorphic basement, and the strata in Jiaolai Basin in the area and the deep morphology and characteristics of major ore-controlling structures in the area. To this end, section measurement was carried out using the integrated geophysical exploration of high-precision gravity survey, high-precision magnetic survey, and magnetotelluric sounding. Meanwhile, the obtained gravity, magnetic, and resistivity data were comprehensively researched and analyzed in combination with previous results. This study will provide a basis for the late prospecting prediction of deep gold deposits and related researches of the area.
