The track-bearing lithologic unit represents a period of high-frequency depositional cyclicity on a very shallow and partly restricted inner shelf.
Below the lower unit and close to the contact with the G oldenville Group, a single outcrop of finer grained, massive, black slate suggests that a third lithologic unit may be present.
Samples were taken from each lithologic unit of the Byram formation and the genera present were identified and counted.
Lithologic units of KIA are further subdivided in to northern, central and southern terrane.
These diagnostic spectral features can provide a way to detect or identify minerals to distinguish lithologic units and to determine wall rock alteration products [22] by using remote sensing.
Brenner (1976) described several species of the genera Fabanella, Macrodentina, Pontocyprella, Schuleridea, Cythereis, Paracypris, Asciocythere, Haplocytheridea, Eocytheropteron, Paranotacythere, Cytherella, Metacytheropteron, Dolocytheridea, Clithrocytheridea (all brackish-marine), Darwinula, Theriosynoecum and Cypridea (all predominantly freshwater) from the Barremian and Aptian of the larger area around Morella (from several localities), but did not give any sections or lithostratigraphic schemes enabling us to identify his sample points und thus help with chronostratigraphic correlation of the actual lithologic units (Fig.
Thus, although all of its facies are not found at all of its outcrops, the continuity, the oneness, of the San Hipolito from Punta Quebrada to Sierra de los Placeres is established upon the fact that at least one, and generally more, of its lithologic units can be recognized from one of its outcrops to the next, its bed of pink dolomite constituting a particularly good marker.
The output is most commonly a map showing predicted lithologic units, structures and suggested field traverses or a series of maps that show predicted units (bedrock, surficial, tectonic, etc.
