摘　　要：广西贺州清水塘硅灰石矿床位于华南板块南华活动带(Ⅱ)桂中—桂东褶皱系(Ⅲ)大瑶山凸起(Ⅳ)东北部,历经多期构造运动,地质构造复杂,褶皱、断裂发育,中生代岩浆岩多次侵入形成姑婆山复式岩体,富含硅质的下石炭统地层与岩体接触,发生接触交代变质作用,形成了似层状或脉状的硅灰石矿体。主矿体矿石平均品位71.28%,矿石质量优良。The Qingshuitang Wollastonite Deposit in Hezhou City of Guangxi,is located in the northeastern part of the Dayaoshan Uplift(IV)of the Central-Eastern Guangxi Fold System(III)of the South China Active Belt(II)of the South China Plate.After multiple tectonic movements,the geological structure is complex,and the folds and faults are developed.The Mesozoic magmatic rocks have invaded many times to form the Guposhan composite granitic bodies.Ores were formed in contact metasomatism metamorphism during the siliceous Lower Carboniferous strata are in contact with the granitic bodies,and the hydrothermal intrusion occurs.The ore bodies are layered or large vein-like and the average grade of the main ore body is 71.28%,the ore quality is excellent.
