Abstract

The Coast Range Batholith north of Vancouver, British Columbia, comprises within the mapped area rocks ranging in composition from granitic pegmatite to gabbro. The most widespread rock is the Capilano quarts-diorite which is markedly heterogeneous, and contains on the average about 3% inclusions. In relative abundance, the quarts-diorite is followed by the Hollyburn granodiorite, More than 80% of the batholithic rock is of these two types. Within the batholith are several roof pendants composed of early Mesozoic volcanics and sediments. One of the most interesting features within the area are the dykes. Although many lie wholly within the batholith, evidence is presented which indicates that they are pre-batholithic. These pro-batholithic dykes are thought to have a significant bearing on the problem of emplacement of the batholithic rock. The marked heterogeneity of most of the batholithic rock, the distribution and alteration of the inclusions, microscopic textural relationships, and certain other data suggest that much of the exposed batholithic rock occupied its present position by some process of replacement rather than by forceful intrusion. It is recognized, however, that due to the nature of the country, the scope of the work, and to some extent due to the nature of the problem, the evidence is not conclusive.
