Fig. 3. Schematic outcrop map (not to scale), showing field relationships of different rock types: granite, diorite (Bonsall tonalite, quartz diorite), granodiorite (grd), and amphibolite dike. Elongate black blebs are xenoliths of amphibolite. Pink outlined areas are photo locations in Collins (1988b), but only photo number 7 is shown in this article (Fig. 7).
