|Name||Waits River Formation|
|Original map label||Dw|
|Comments||Part of Eastern Vermont The age of the Waits River Formation is considered Silurian and Devonian and is controversial. Silurian age is based on isotopic dating by Aleinikoff and Karabinos (1990) and the Devonian age based on fossils (Hueber and others, 1990) (Ratcliffe, in press) per VT008.|
|Primary rock type||limestone|
|Secondary rock type||phyllite|
|Other rock types||mica schist|
Sedimentary > Carbonate > LimestoneGray quartzose and micaceous crystalline limestone; where more metamorphosed the limestones contain: actinolite, hornblende, zoisite, diopside, wollastonite, and garnet
Metamorphic > Schist > Mica-schist > Biotite-schistinterbedded and intergradational with gray quartz-muscovite phyllite or schist; where more metamorphosed: the phyllite and schist contains: biotite, garnet, and locally andalusite, kyanite or sillimanite.
