Revised as basal member (of 3) of Altamont limestone of the Marmaton group in southeastern KS. Extends from Carroll Co, MO far into southeastern KS in the Forest City basin. Is 0.4 ft thick in a measured section in NW1/4 SW1/4 sec 29, T25S, R23E in Bourbon Co, KS in Cherokee basin, and is 6 ft thick in another measured section in Labette Co, KS in Cherokee basin. For many miles along its outcrop, Tina limestone member is not more than 2 ft thick, and generally thickness is less. Consists of mostly gray, buff-weathering, nodular, earthy limestone having a sparse molluscan fauna. Contains much algal material in upper part; gastropods; SQUAMULARIA common. Locally grades laterally into calcareous sandstone. In many exposures is cross-bedded. In southern part of KS line of outcrop, Tina thickens to as much as 16 ft and is a mass of CHAETETES colonies. Overlies Bandera shale of Marmaton group; underlies Lake Neosho shale member (new) of Altamont limestone of Marmaton. Cross section. Of Pennsylvanian, Des Moines age.

Abandoned. Replaced by Amoret limestone member (new) which is lower member of Altamont formation of Marmaton group. Name Tina is inappropriate because type section of Tina is actually Higginsville member of Fort Scott formation. Within study area in MO, Amoret outcrops in Bates, Grundy, Sullivan and Putnam Cos, Forest City basin and Adair Co, Lincoln anticline.
