... currently in progress. Analysis of these data support Prevot and McWilliams’ (1989) correlation of the Orange Mountain, Preakness, and Hook Mountain Basalts with the Talcott, Holyoke, and Hampden Basalts, respectively. Their correlation of the Deerfield Basalt with the Holyoke Basalt and the Preakness...

... of basalts match the composition of Orange Mountain Basalt. Two stratigraphically higher basalts correlate with Preakness Basalt. Differentiation models indicate that granophyric diabase can be produced from chill-margin composition by removal of pyroxene, plagioclase, and olivine, and addition of Fe/Ti...
