slickensides The Juniata is defined as a grayish-red to greenish-gray, thin- to thick-bedded
siltstone,
shale, and very fine to medium-grained
crossbedded sandstone or
subgraywacke and
protoquartzite with interbedded conglomerate. The Juniata is a lateral equivalent of the
Queenston Shale in western
Pennsylvania.
Depositional environment The
depositional environment of the Juniata has always been interpreted as mostly terrestrial or shallow marine deposits resulting in a
molasse sequence produced by the
Taconic orogeny.
Fossils Very few fossils exist in the Juniata Formation, but different types of trace fossils such as tracks and burrows can commonly be found. ==Age==
