• Skarn-type mineralization of the Cuonadong Sn-W-Be polymetallic deposit occurred at ca. 15 Ma. Skarn-hosted scheelite can be divided into an older type 1 and a younger 2 scheelite. The ore-forming fluid was exsolved from Miocene leucogranite. Geochemically isotopically, modified by intense fluid-rock interaction during skarnization greisenization. is first rare-metal with extraordinary metall...

sorkheh-dizaj apatite-iron oxide deposit is located 32 km southeast of zanjan. the area is situated within the tarom subzone of western alborz-azarbaijan structural zone. the oldest units at the sorkheh-dizaj area are eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciate tuff and lapilli tuff which intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton o...

the study area is a part of cenozoic magmatic belt of central iran, which is located in the west of yazd porovince. contact metamorphism and skarn occurred in conglomerate part of sngestan formation. the oligocene intrusion bodies of ali-abad-darreh zereshk are leucocerate and have the chemical composition of granite to granodiorite with calc-alkaline affinity from volcanic arc geological setti...

The Huanggang deposit is the most important and largest skarn Fe–Sn polymetallic in Southern Great Xing’an Range of Northeast China. Cassiterite, magnetite, other metal minerals are related to garnets within systems. zoned from various stages able record numerous geological mineralizing processes including variations physicochemical conditions hydrothermal fluid evolution. In this contribution,...
