浙江青田周村雕刻石-叶蜡石矿床特征及工作方法

Work method and carving stone-pyrophyllite deposit characteristics in Zhoucun,Qingtian,Zhejiang

青田石是中国四大名石之一,享誉国内外。为满足青田石雕业可持续发展的需求,继青田石主要产地山口镇之后,在阜山镇周村进行的地质普查,提交333叶蜡石资源量140余万吨,雕刻石近2万t。周村叶蜡石矿床属火山热液蚀变型,其中雕刻石(冻石)属充填-交代而成,矿石多产于节理裂隙中。矿区共发现2个矿化带、7个矿体,呈似层状产出,上层为高铁叶蜡石矿体,下层为三级品叶蜡石矿体。专门针对雕刻石进行的地质勘查在浙江省尚属首次,即无前人经验可借鉴,也无相关规范可参考,对周村雕刻叶蜡石普查的工作方法进行了总结,以供同行参考。

Qingtian stone is famous in the world as one of the four famous stones of China.In order to meet the requirement of sustainable development of Qingtian carving stone industry,except for Shankou Town as the main origin of Qingtian stone,geological survey had been carried out in Zhoucun of Fushan Town.It has been submitted for about 1.4 million tons of pyrophyllite resources and nearly 2 million tons of carving stone of 333 level.Zhoucun pyrophyllite deposit is belonged to volcanic hydrothermal alteration type,carving stone(pagodite)is formed by filling-replacement progress,ore is usually found in the joints and fissures.There are two mineralized zones and seven ore bodies in the mine with semi-layered occurrence,high iron ore pyrophyllite is in the upper layer,and the third grade pyrophyllite ore is in the lower layer.For it is the first time to carry out geological survey on the carving stone in Zhejiang Province,there is no previous experience to be used for reference and no relevant norms can be referred to.The article has summarized the work method of Zhoucun pyrophyllite general survey,which can be taken for reference as well.
