摘要
广西壮族自治区贺州市开山镇A1矿区优质饰面花岗岩矿赋存于姑婆山复式岩体中的姑婆山岩体晚侏罗世花岗岩,主要岩性为浅肉红色中-粗粒(或中粒)斑状黑云母正长花岗岩。本文主要阐述了该区饰面花岗岩矿的主要矿体形态、产状、规模,分析了矿石的类型、品种及物理性能、放射性、荒料率等质量特征。矿石花色品种为“贺州红”,根据目前市场行情,属于中-高档饰面石材,具有较好的开发利用价值。本次研究为贺州市开山镇A1矿区饰面花岗岩的进一步勘探开发提供了地质依据。
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.
