Three lithostratigraphic units of fluvial origin (Members) and two paleosols have been differentiated.
For the calculation of the thermal field of the basin, all lithostratigraphic units of the model have been characterized with average values for the thermal conductivity and the radiogenic heat production according to their lithological composition (Table 2).
The Big Cottonwood Creek Member is a newly recognized lithostratigraphic unit of the Chadron Formation of northwestern Nebraska.
This SB also marks the onset of the fluvio-deltaic Benin lithostratigraphic unit of the delta.
The underlying bedrock is predominantly sandstone from the Buntsandstein, a lithostratigraphic unit of the Lower Triassic series (Rapp 2002).
It is important to note that Lucas did not (at this time) modify the basic lithostratigraphic framework of the Petrified Forest Formation in the park established by previous workers, only the nomenclature.
After almost a century of research, it is astonishing that controversy remains about the basic lithostratigraphic framework of the Chinle Formation in Petrified Forest National Park, and it is absolutely essential to resolve these controversies before the nature and timing of faunal and floral change during the Late Triassic in northeastern Arizona can be understood.
From the 1950s through the end of the 20th century, the basic lithostratigraphic framework of the Chinle Formation within the southern part of PEFO was thought to be well understood, with only minor disagreements (e.g., [5], [16] [22]), and a significant turnover of the vertebrate fauna was recognized as occurring within the beds most workers called the Petrified Forest Member [3], [5], [23] [25].
The regional geology of the Niger Delta is relatively simple consisting of three lithostratigraphic units, Akata, Agbada and Benin Formations, overlain by various types of quaternary deposits (Short and Stauble 1967; Wright et al. 1985; Kogbe 1989).
Our shortening estimate relies on accurate thicknesses of lithostratigraphic units, in most cases thinner than applied before.
