Abstract: The high-quality decorative granite deposit in A1 mining area of Kaishan Town, Hezhou City, Guangxi Zhuang Autonomous Region, is located in the late Jurassic granite of the Guposhan pluton in the Guposhan complex. The main lithology is shallow flesh red medium to coarse grained （or medium grained） porphyry biotite syenogranite. This article mainly elaborates on the main ore body morphology, occurrence, and scale of the decorative granite ore in the area, and analyzes the quality characteristics of the ore type, variety, physical properties, radioactivity, and waste material rate. The variety of ore color is “Hezhou Red”, which belongs to the medium to high-end decorative stone according to the current market situation and has good development and utilization value. This study provides a geological basis for the further exploration and development of decorative granite in A1 mining area of Kaishan Town, Hezhou City, Guangxi Zhuang Autonomous Region.
