7. Application Case 2: Predicting Metallogenic Potential in Shandong Province’s Jiaojia Gold Belt Through 3D Modeling

This chapter delves into the application of 3D modeling to predict metallogenic potential in the Jiaojia Gold Belt of Shandong Province. It begins with a thorough examination of the geological context, including regional stratigraphy, tectonics, and magmatic activity, which provides a foundation for understanding the metallogenic environment. The chapter then outlines the process of creating a 3D geological model, incorporating data from exploration lines, controlled source audio magnetotelluric measurements, and geochemical element combination anomalies. The modeling process involves the use of Surpac software to construct a comprehensive 3D model that includes rock formations, structural elements, alteration zones, and known ore bodies. The chapter also discusses the extraction of metallogenic favorable information and the establishment of a cubic model for quantitative prediction. The results of the 3D modeling and prospecting methods are used to identify favorable areas for gold exploration, with a focus on the Jiaojia major fault zone and its branch faults. The chapter concludes with a discussion on the implications of these findings for future exploration efforts in the region. Readers will gain insights into the advanced techniques used in mineral exploration and the geological factors that influence metallogenic potential.
