Fig. 7. Quartz diorite encloses a dark amphibolite dike on left and at one time also enclosed a thick part of the dike on the right. A thin remnant of the quartz diorite encloses the amphibolite on both sides, and fingers of the amphibolite extend into the quartz diorite but not into the granite. A thin granite vein extends through the amphibolite, and myrmekite-bearing granite also extends between the thin and thick parts of the amphibolite dike parallel to the quartz diorite-granite contact. Arrows point to two diamond-saw cuts where samples were broken out and where all transition stages between the quartz diorite and granite can be observed in thin sections.
