摘要
福建省是全国萤石矿资源的主要分布区之一,全省累计查明的Ca F2资源量超过2000万吨,约占全国的10.5%。萤石矿床(点)主要分布在政和—大埔断裂带西部,特别是集中分布在政和—大埔断裂带以西及南平—宁化构造带以北的闽西北隆起带。萤石矿主要赋存于燕山晚期北东—北北东向构造断裂带中,与燕山早期花岗岩关系密切,围岩蚀变主要为硅化。
Fujian Province is one of the main distribution areas of fluorite resources in China. The total amount of CaF2 resources in Fujian Province is more than 20 million tons, accounting for 10.5% of the whole country. The fluorite deposits are mainly distributed in the west of the Zhenghe-Tai Po fault zone, especially in the west of the Zhenghe-Tai Po fault zone and the northwestern Fujian uplift zone, north of the Nanping-Ninghua structural belt. Fluorite deposits mainly occur in the late Yanshanian NNE-NNE structural fault zone, which is closely related to the early Yanshanian granite, and the wall rock alteration is mainly silicification.
