摘要:福建省螢石礦產(chǎn)資源豐富,分布較廣,劃分出3個螢石成礦亞帶、8個螢石成礦遠景區(qū)。主要分布在南平市和三明市所管轄市縣,主要產(chǎn)于崇安—安遠北東向深大斷裂帶,浦城—嵩口、將樂—華安、泰寧—龍巖南北向斷裂帶,光澤—武平北北東向斷裂帶,且多在侵入巖與圍巖接觸帶附近,近年來應(yīng)用新技術(shù)、新方法找礦效果良好。

Abstract: Fujian province has abundant and widely distributed fluorite mineral resources, which are divided into three fluorite mineralization sub zones and eight fluorite mineralization prospect areas. Mainly distributed in the cities and counties under the jurisdiction of Nanping city and Sanming city, it is mainly produced in the Chong’An-Anyuan ne-trending deep and large fault zone, the Pucheng-Songkou, Jangle-Hua’an, Taining-Longyan north-south trending fault zone, and the Guangze-Wuping north north east trending fault zone, in recent years, new techniques and new methods have been applied to find ore deposits with good results.
Keywords: fluorite; resources; fault zone; granite
螢石是一種熔點較低的礦物,熔點在1 270~1 350 ℃,主要化學(xué)成分為氟化鈣(CaF2),是冶金行業(yè)不可缺少的熔劑,也是氟化工行業(yè)的資源保障,主要應(yīng)用于新能源(風(fēng)能、太陽能)、新能源汽車(鋰電池、密封件)、核工業(yè)(鈾加工)、新一代信息技術(shù)(半導(dǎo)體、平板顯示)等行業(yè)[1-2],對國家經(jīng)濟安全和戰(zhàn)略性新興產(chǎn)業(yè)具有重要作用。(剩余3346字)
