Skarn mineral characteristics and zonation of the Makeng Fe-Mo deposit in Fujian Province. Acta Petrologica Sinica，30( 5) : 1339 － 1354 Abstract The Makeng Fe-Mo deposit is a large deposit hosted in the interlayer fracture zone between carbonates of Huanglong ( ) ( ) Formation C h and clastic rocks of Lindi Formation C l at the exo-contact zone of the Juzhou-Dayang granite. The iron ore are 2 ， 1 ， closely coexisting with skarns. However the ore genesis here has still been controversial. In this paper we studied the mineralogical ， characteristics of skarns in Makeng Fe-Mo deposit with electron microprobe analysis which showed that the mineral assemblages of ， ， skarns in this deposit mainly consisted of pyroxene garnet and bustamite. The retrograde altered minerals were comprised of chlorite ， ， ， epidote amphibole and quartz. The mineral composition of clinopyroxene are diopside hedenbergite and a small amoun
