Abstract

INTRODUCTION

Red Hill, New Hampshire, received attention from early geologists who worked in this region,1 and it was the subject of an extensive paper by Pirsson and Washington.2 Although certain of the rock types were adequately described in these papers, it is apparent from field examination that the distribution of the rocks has not been shown in sufficient detail and that several of the rock types have never been described. The present paper, therefore, includes a more detailed map than has heretofore been presented, descriptions of the previously undescribed rocks, and some discussion of the relationships of the different types of rocks.

The six new rock analyses here presented were made possible by a grant from the Penrose Bequest of the Geological Society of America. The writer wishes to express his sincere thanks to the Society for its generosity. He also wishes to thank Professor Esper S. Larsen and . . .
