摘要: Recent studies have revealed that the Makeng Fe deposit is a skarn type deposit. However, skarns in Makeng, occurring primarily between limestone and sandstone, are not typically associated with plutons. Different periods of intrusions, e.7. Hercynian mafic intrusions Yanshanian (i.e. early Cretaceous) Dayang–Juzhou granitic intrusion, occurred district. In this study, formation processes mineralization constrained by detailed fieldwork, petrology, geochronology, geochemistry. Skarns intersecting observed consecutive specimens from 106# tunnel. They suggest after related to later intrusion. The geochronological characteristics weakly skarn-altered diabases, decreasing nature contents altered diabase, major element compositions pyroxenes garnets also support strongly reformed magmas migrated intrusion was responsible for iron ore.
