摘要: 青田石被誉为我国“四大国石”之一而蜚声海内外。随着优质篆刻用青田石资源的枯竭,亟需通过矿业遗迹调查与评价工作为契机,展开遗迹保护与矿山公园的前期工作。通过青田县山口矿区野外实地考察,开展对矿床及其典型地质剖面的描述与拍照,结合该地出产的青田石雕,利用地层、构造及火山地质等研究成果揭示青田石特色花纹、品种、找矿标志等的形成原因。从科学价值、稀有性、保存情况三个方面对矿物岩石花纹遗迹和找矿地质标准遗迹进行评价,得出这两类典型矿产地质遗迹均达到国家级的结论。这些遗迹综合反映了青田石的形成过程与其人文、美学特征,具有很高的科学、观赏、科普与旅游开发价值。目前需要对遗迹采取分批保护,为申报矿山公园创造基础条件。Abstract: Qingtian stone is renowned for one of“The Four National Carving Stones”both at home and abroad.As high quality resource of Qingtian stone carving dried up gradually,local people expect geological experts to start working on mine heritage conservation and mine park construction after investigation and assessment of mine heritage.After field investigation in Shankou mining area of Qingtian county,the author photographed and described the deposit and typical ecological sections of Qingtian stone.What’s more,the paper revealed formation process about the unique patterns,varieties,ore prospecting marks of Qingtian stone with the help of studies both on stratigraphy,geological structure and volcano geology and on local Qingtian stone carvings.This paper concluded those two typical geological relics mentioned above had reached our national standard in terms of scientific value,rarity and preservation condition.Those two mine heritages reflected the formation process and the humane,aesthetic characteristics of Qingtian stone and had a high value of science and tourism.These geological relics need preservation group by group in order to create basic conditions for mine park application.
