浙江省非金属矿产种类较多,资源比较丰富,与中生代陆相中酸性火山岩有关的非金属矿产更有其特色,萤石、叶腊石、明矾石素有浙江“三块石头”之称.1980年第一次全国非金属矿地质工作会议后,浙江地矿局对非金属矿产地质工作加强了力量,“六五”期间用于非金属矿产地勘费,占固体矿产总投资的29.5%,钻探工作量占固体矿产 Zhejiang Province has many types of non-metallic minerals and abundant resources. The non-metallic minerals associated with the Mesozoic continental acidic volcanic rocks are more distinctive. Fluorite, pyrophyllite and alum are known as “three stones” in Zhejiang. After the National Non-metallic Mineral Geological Work Conference, the Zhejiang Geological and Mineral Bureau strengthened the geology work of non-metallic minerals. It was used for non-metallic mineral exploration fees during the “6th Five-Year Plan” period, accounting for 29.5% of the total investment in solid minerals, and the drilling workload.
