Summary
Martaban pit of the Tennessee Coal, Iron & Railroad Company. Southwest side of cut opposite exposures shown in images 1497 to 1500 showing small faulted blocks of Tuscaloosa sand. The faulting is best shown by the differences in color of the sand. The faulting may have been due to movement of the beds or to slumping above a solution channel in Conasauga limestone. A gully eroded in the sand has directed iron- bearing waters downward forming trough-shaped incrustations of sandy limonite, some of which run continuously through the faulted blocks and are later than the faulting. Tuscaloosa County, Alabama. December 8, 1929.
