A combination of petrographic observations, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and statistical data exploration was used in this study to determine compositional variations in hydrothermal and igneous magnetite from five porphyry Cu–Mo and skarn deposits in the sout...
setting of Late Archean to Late Proterozoic continental rift They include porphyry copper and stratiform ones, which represent the submarine conduits of hydrothermal fluids (e g the Tongkuangyu deposit) and exhalative-sedimentary products (e g the Henglingguan, Hu-Bi and Luojiahe deposits), ...
The major ore minerals are chalcopyrite, with a small amount of pyrite, bornite and arsenopyrite. The wall rock alteration includes silicification, phyllic and propylitic alterations, which are similar to those of the porphyry Cu deposits. The monzonitic granite porphyry is mainly composed of ...
