| Abstract: | The Houyang pyrophyllite deposit in Fu'an, Fujian Province, with the stratoid structure, consists in volcaniclastic rocks of the middle part of the Late Jurassic Nanyuan Formation(J 3n) strata in which four orebodies have been discovered. The ores in the surveyed area can be divided into two kinds: quartz pyrophyllite and illitic pyrophyllite, mainly quartz pyrophyllite. The orebodies of the pyrophyllite deposit are obviously controlled by the stratum and lithology and it belongs to the stratoid pyrophyllite deposit of volcanic hydrothermal metasomatic alteration. |
