|Name||Green Pond Conglomerate|
|Geologic age||Lower (?) and Middle Silurian|
Sedimentary > Clastic > Conglomerate (Bed)Medium- to coarse-grained quartz-pebble conglomerate; grades downward into gray, very dark-red, or grayish-purple, medium- to coarse-grained, thin- to very thick bedded pebble to cobble conglomerate containing clasts of red shale, siltstone, and chert. Red arkosic quartz-pebble conglomerate and quartzite are more abundant than gray and grayish-green quartzite.
