Excursion 7.- Saturday, Nov. 16. Mr. J. H. Sears. The eruptive rocks of Salem and Marblehead.

At Salem Neck the excursion will visit the outcrops of Essexite, a petrographic type of great importance, which is here cut by younger masses of angite and elaeolite syenite. These rocks are traversed by a series of gabbro dikes and by a still younger series of tinguaites which cut all the older formations. Thence proceeding to Marblehead Neck, granite will be seen intrusive through the Cambrian rocks, the keratophyre sheet overlaying the old rhyolites, and finally the more recent quartz porphyry dikes.
