Abstract
I. Introduction. In a recent communication to this Society 1 I described the intrusion of a granite into a diabase at Sorel Point, on the northern coast of Jersey, and in concluding remarked on another paraUel case to be found on the southern side of the island. It is to this that the present paper relates. The rocks from north and south, both intrusive and intruded into, show a resemblance one to another sufficient to indicate that they are closely related. The interior of the island is occupied by the rather varied assortment of igneous and sedimentary rocks depicted on M. Noury's map. 2 From the town of St. Helier's to La Rocque Point, the south-eastern termination of the island, the receding tide exposes to the view of an observer standing on the low shore an assemblage of jagged rocks which stretch far out towards the horizon. Near the centre of St. Clement's Bay an intrusive granite is found about high-water mark, and forms at the western end the more outlying crags of Le Nez Point. At Grève d'Azette, the next bay to the west-ward, it again approaches the shore. Diabase and other closely-related rocks make up Le Nez itself. At the junction of the two the granite sends innumerable offshoots and dykes into the older rock, which are well seen to the west of Le Nez. Generally these dykes are dearly cut and weU defined; but occasionally peculiar rocks make their appearance, so similar to those non-homogeneous and mixed rocks which
