Summary:

A. Wing, v. 13, p. 334-347, 404-419. Showed oldest formation of western Vermont as "gneiss, often called Green Mountain gneiss."

Summary:

Pg. 464. The Green Mountain gneiss underlies the green schists in Green Mountains. The Green Mountains are not Huronian but are flanked by it on both sides in northern half of Vermont. They belong to Montalban series and are nearer the Laurentian than the Huronian. The use by Dr. Hunt in 1871 of Green Mountains gneiss for the Huronian is improper and inappropriate.

Summary:

Pg. 249-256. Green Mountain series (of gneisses, schists, etc.) covers eastern part of Burlington quadrangle, Vermont. I believe they are made of Cambrian and Ordovician strata.
