Pg. 90. Randolph phyllite. Fine-grained phyllites, of either very dark-gray or bluish-gray color, and with schistose structure. Are interbedded and interstratified with Waits River limestone. Are the phyllite part of Memphremagog group, and in Bethel Township, and doubtless to southward, are the predominant phase of that group. Extend in north-south direction, entirely across Randolph Township [Randolph quadrangle, Orange County, northeastern Vermont]. Are older than Bradford schists, which overlie Waits River limestone, and younger than Orleans phyllite, which underlies Waits River limestone.
