Extract

In the course of some traverses of the central region of Anglesey recently made, preparatory to mapping it out in detail, I observed a few facts which, in spite of the evident complexity of the structures, can, I think, be safely described before completion of the map, and are of some interest in connection with other recent researches in gneissose areas.

1 In the recognition of these peculiar modes of granitic injection will, I think, be found a reconciliation of the conflicting views that have been held as to the intrusive or “interbedded” character of the granite. I should like also to draw attention to the very vivid and faithful description of these phenomena by Sir A. C. Ramsay (“Geol. North Wales,” ed. 2, p. 243).
