The scattering of electrons with an energy of 2.25 Mev is studied in the foils of aluminum, copper, iron, molybdenum, silver, tin, tantalum, gold, and lead. The results obtained are compared with ...
This zone has very low concentrations of copper and molybdenum but has consistently elevated gold concentrations typically between 150 and 500 ppb (Lang et al., 2008). The auriferous peripheral ...
In comparison, the southern subzone contains numerous skarn–porphyry copper, molybdenum, gold, tungsten and antimony deposits. The middle subzone hosts the majority of the mineralization (in the form of both skarn–porphyry and Fe-oxide–apatite deposits) within the MLYRMB and is split into seven individual ore districts ( Chang et al ...
