Interlayer gliding breccia-type gold deposit, hosted in a low angle interlayer gliding fault between an Early Cretaceous conglomerate and Lower Proterozoic metamorphic rocks. Ore bodies are located in tectonic breccias in the main slip fault zone.

A total of 14 gold orebodies have been delineated in the Pengjiakuang gold deposit, with the primary orebodies including Ⅰ-1, Ⅱ-1, and Ⅰ-2. The largest Ⅰ-1 orebody, under the strict control of the Pengjiakuang fault, exhibits a length of 300 m, widths ranging from 1.50 m to 25.00 m, thicknesses between 0.64 m and 41.92 m, occurrence elevations from +95 m to −107 m, and a maximum depth along its dip direction of 490 m (unclosed in deep strata). The orebodies in the deposit have relatively simple morphologies, occurring as veins primarily, with branching and recombination occurring locally. They generally show a gently wavy distribution pattern consisting of a steep upper part and a gentle lower part along their strikes and dip directions, with morphologies strictly governed by nearly EW-trending faults. Their thicknesses vary significantly from 0.64 m to 41.92 m (average: 10.28 m), presenting a wide top and a narrow bottom; the gold grades of the orebodies range from 1.00 g/t to 8.48 g/t, with an average of 3.24 g/t. the Pengjiakuang gold deposit experienced metallogenic stages in chronological order: The quartz-pyrite stage (stage I), the gold-bearing quartz (sericite)- pyrite stage (stage II), the quartz-polymetallic sulfide stage (stage III), and the quartz-carbonate stage (stage IV). Among them, stages II and III are major stages for gold enrichment, whereas no ores were formed in stage IV.
