Summary:
Pg. 31-43. Allsboro sandstone. Coarse-grained sandstone, in places decidedly contorted, thus differing from other sandstones in the region. At a few places contains a little asphaltic material. Thickness 8 feet.
Named from small village in AL, near MS line. Overlies Alsobrook formation and underlies Southward Pond formation. Is correlated with Bethel sandstone [not true Bethel, but Yankeetown chert; true Bethel sandstone underlies Renault formation, which which Morse correlates his Alsobrook formation.] [Age is Late Mississippian (Chester).]
Named from small village of Allsboro in northwestern AL, near MS line.
