摘要
管坑石墨矿床位于华夏板块北缘北武夷隆起与抚州一饶南拗陷交接处。矿体长400～1200m，厚1．22-18．63m，呈似层状、透镜状，顺层产于上震旦-下寒武统外管坑组中深变质岩中，矿床规模达大型以上，成因类型属沉积变质叠改型。矿石类型以片岩型为主，矿物成分主要为晶质石墨，片径大者0．15mm，小者0．01mm，多数界于0．02-0．04mm之间。
Guankeng graphite mine ore bed is located between the north Wuyi upwrap of Cathaysian plate and Fuzhou - Raonan depression. The bed is 400 - 1200m long, 1.22 - 18.66m thick, shows quasi laminate and lenticular geological feature, which is considered as a large - scale ore bed. The rock type mainly contains schist, with its main mineral composition of cryptocrystaUine graphite. The biggest schist is up to 0. 15mm, smallest down to 0. 01mm, with most between 0.02 -0.04mm.
