In the Emeishan large igneous province, SW China, there are many layered mafic–ultramafic intrusions such as the Baima, Hongge, Panzhihua and Taihe intrusions that host world-class Fe–Ti oxide ore deposits. Despite numerous studies, the origin of these deposits still remains elusive. This includes the role of crustal contamination, especially addition of external CO2 from carbonate country rocks during...
To better understand Fe isotope fractionation between mafic minerals and oxides during crystallization of mafic magma and sub-solidus re-equilibration, the Fe isotopes of whole-rocks and separated minerals (olivine, clinopyroxene, magnetite and ilmenite) of the Baima mafic layered intrusion, SW China, have been investigated. The separated minerals show a systematical decrease in δ 57 Fe values,...
