Summary:
The Jumping Branch Manganiferous Member of the Battleground Formation is here named in the Kings Mountain belt, NC and SC. It was described as the "manganese schist member" of the Battleground by Keith and Sterrett (1931). It consists of fine-grained equigranular spessartine-almandine garnet and quartz rock (coticule or gondite) interlayered with quartz-sericite schist or phyllite. The dusky-brown color of secondary oxides and hydroxides of manganese and iron in weathered rock and saprolite make the Jumping Branch Member a distinctive marker unit. Overlies the Dixon Gap Metaconglomerate Member and underlies the Draytonville Metaconglomerate Member of the Battleground. Age is Late Proterozoic.
