... schist and gneiss of the Tatnic Hill Formation, Hebron Formation, Scotland Schist, and the sill-like Canterbury Gneiss overlies the Quinebaug Formation. These rocks produce a field of moderate levels of radioactivity but have nodes of high radioactivity where pegmatite is abundant. A field of moderate...

...-sillimanite-muscovite-biotite-plagioclase-quartz schist and biotite-hornblende-plagioclase-quartz gneiss. These units correlate with the Yantic and Lower members, respectively, of the Tatnic Hill Formation, included in the Putnam-Nashoba terrane in eastern Connecticut. The rocks below 815 m in the Moodus...

... in the Acadian orogen is an important new petrotectonic problem. The precipitates occur in a belt at least 25 km long in the Brimfield Schist and the adjacent Tatnic Hill Formation ( Fig. 1 ). The exposures are dominated by metapelitic and quartzofeldspathic gneisses, but also include pods and layers of calc...

..., garnet peridotites, and mantle xenoliths ( Sobolev and Lavrent’ev 1971 ; Vrána 2008 ). Finally, ZrO 2 contents in rutile coexisting with a silica polymorph that approach the weight percent level indicate extremely high- T of formation in excess of 900 °C regardless of pressure ( Tomkins et al. 2007...
