FIG. 5. Illustration of the complicated distribution of various rock types in
the southern Roby zone in the Mine Block intrusion after 1:60 scale mapping by
Hinchey et al. (2003). Rocks are divided into early leucocratic, mineralized
melanocratic, and late barren melanocratic rocks. The mineralized melanocratic
rocks are commonly accompanied by pegmatitic veins and pods of various sizes
from several centimeters to 50 cm. Only large pegmatites are shown in the map.
Felsic and diabase dikes cut all rock types of the Lac des Iles intrusive
complex. Numbers on the sides correspond to the mine grid.
