The Luanjiagou borate deposit is located in the Paleoproterozoic Jiao-Liao-Ji orogenic/active belt of the North China Craton. The strata in the area are mainly the Lieryu Formation and the Gaojiayu Formation of the Proterozoic Liaohe Group. The tectonic framework is composed of a series of folds and faults. The magmatic rocks are not developed. There are more than 10 lenticular and lenticular ore bodies, and the wall rock alteration such as serpentinization and chloritization is widely developed. The typical structural features and tectonic systems of the Luangougou borate deposit are systematically studied by geomechanical method, the results showed that the direction of the principal compressive stress in the study area has evolved and transformed from northsouth compression to northwestwest-southeasteast compression-torsion. The mineralization tectonic evolution process can be divided into five stages: “sedimentation→metamorphism→fold-controlled mineralization→fracture-destructive mineralization→final shaping”. The analysis results of the tectonic-mineralization relationship show that the interlayer sliding zones developed in the core, two wings, and hinge zone of the overturned folds, as well as the structural void spaces such as fracture fracture zones and joint-fissure zones, provide key locations for the enrichment and emplacement of ore-forming materials and are favorable sites for borate mineralization. Based on the comprehensive tectonic evolution laws, structural ore-controlling characteristics, combined with orebody geological parameters such as orebody shape, thickness, and grade, the deep prospecting potential prediction was carried out. It is indicated that the area west of the 176 exploration line has good potential for borate resource replacement, and it is recommended to deploy drilling projects in this target area for deep resource verification.
