招平断裂带是胶东三大千吨级金成矿带之一。该断裂带中段的焦格庄—夏甸一带主要矿床的探矿深度已达2 km，其深部及外围仍有较大的找矿空间。为了详细掌握该区域的找矿前景，为新一轮找矿突破战略行动提供基础依据，采用平面地质图、图切地质剖面和探矿工程数据，结合重磁电三维物性反演，利用人机交互式建模技术，建立了-4 000 m以浅三维地质体模型。通过对三维地质模型进行空间分析发现，控矿断裂由浅部至深部呈倾角陡、缓交替的阶梯式变化，在断裂倾角陡、缓转折段和倾角较缓段，金矿化富集程度高，金矿体具有向NE侧伏和等间距分布规律。基于构造走向转折地段、构造倾角转折部位、构造表面变化率、矿体倾向等间距性和矿体侧伏5个特征变量建立了招平断裂带中段综合找矿预测模型，圈定深部找矿靶区12处。将5个特征变量叠加的信息量值作为关联要素，预测金潜在矿产资源为416 t。经对靶区进行初步钻探验证，发现了工业矿体，实现了招平断裂带中段新的找矿突破。

The Zhaoping fault zone represents one of the three principal gold ore belts，each containing substantial reserves exceeding one thousand tons，within the Jiaodong region.Exploration efforts in the Jiaogezhuang-Xiadian area have reached depths of up to 2 kilometers，indicating significant potential for further exploration in both the deeper sections and the surrounding periphery of this zone.Nonetheless，several challenges hinder mineral exploration in these deeper peripheral areas，including a lack of clarity regarding metallogenic patterns，inadequate signal reception from conventional geophysical methods under，substantial overburden，and the complexities associated with managing extensive datasets generated from deep mining operations.Through the analysis of geological maps，exploration line profiles，and exploration data，alongside the implementation of three-dimensional physical inversion techniques for gravity，magnetic，and electrical properties，a comprehensive understanding of the exploration prospects in the area has been attained.This research provides a foundational basis for advancing exploration strategies in forthcoming initiatives.The three-dimensional geological model was developed by using human-computer interaction modeling technology，it extending from the surface to a depth of -4 000 meters.Spatial analysis of the three-dimensional geological model reveals a pattern of ore-controlling faults with varying angles from the shallow to the deeper sections.It is found that the gold mineralisation is highly enriched in the section of steep and slow dip faults and in the section of slow dip faults，and the gold ore body follows the law of lateral volatility and equidistant distribution to the NE.This study introduces a prospecting methodology informed by the principles of “fault ore control law”combined with a detailed three-dimensional geological model.It identifies regions with anomalous structural morphology as favorable zones for mineralization，thereby addressing the challenge of detecting abnormal ore deposits beneath deep cover.Furthermore，a comprehensive exploration prediction model has been developed for the central segment of the Zhaoping fault zone through the extraction of five characteristic variables，such as tectonic strike reversal section，tectonic dip reversal section，tectonic surface change rate，orebody dip isotropy and orebody flanking.As a result，twelve target areas for deep mineral exploration have been identified.The integration of these characteristic variables has projected a potential gold mineral resource of 416 tons，thereby guiding the direction for subsequent deep exploration.Preliminary drilling of the target area has revealed an industrial orebody，representing a new breakthrough in the search for ore in the Zhaoping fault zone.
