Genesis of Magnetite Deposits I N the Iron Mask Batholith
Significant magnetite, in the form of dyke-like lodes (Cockfield. 1948). occurs in close spatial relationship to copper deposits such as the Afton mine. The genetic relationship of these massive magnetite lodes to the copper deposits of the Iron Mask is unknown, as i s the origin of the magnetite deposits. However, the proximity of these deposits to magnetite-rich intrusive units of the Iron Ma...
