"Changshan-type"fluorite deposits are a new type of deposits discovered in the Qinzhou-Hangzhou metallogenic belt recently. A study of orebody characteristics shows that they are different from filling-metasomatic and stratabound type fluorite deposits in carbonate rocks in location of orebody and characteristics of ores. The orebodies discovered in the past are located on the southeast limb of Yanqian brachyanticline as well as the outer contact zone of Yanqian granite and Cambrian carbonates. The discovery of the Kumalin deposit in the hinge zone of anticline enriches the metallogenic theory of the "Changshan-type" fluorite deposits. The lithologic differences of Cambrian carbonates had no obvious relationship with mineralization. Filling is the main metallogenic mode, as shown by the CaF₂ content of immediate roof and floor. Studies show that the high-F magma that invaded in the late Yanshanian epoch was the most important factor for the formation of the deposit. The roof-fall structure in the outer contact zone of Yanqian granite and interformational tectonic zone seem to be the main ore-controlling structure. Based on the study of the geological characteristics and metallogenic regularity, the authors have summarized the genesis of the deposit, established the metallogenic model and provided the new train of thought for the same type of deposits in northwest Zhejiang and even the whole South China.
