Major objectives of this study have been to define the character of the igneous rocks present; to determine the number of separate igneous complexes, their relative ages, their variations, the relationships of these variations to structure, and the interpretation of their origin; to elucidate the mechanics of intrusion; and to discriminate primary magmatic structures from postconsolidation metamorphic features and to describe and interpret the mineralogic facies as a result of metamorphism. The oldest rocks of the region are crystalline schists, gneisses, granulose rocks, marbles, quartzites, skarns, and amphibolites of the Grenville series. A concept widely held is that the Grenville series was invaded by granite during an early, if not the earliest, period of magmatic intrusion in the Adirondacks, but the present conclusion is that no really satisfactory unequivocal proof for the existence of this older granite intrusion in the northern and northwest Adirondacks, at least, has yet been presented, though it may well be present…
