Stratigraphic analysis of XES02: Implications for the sequence stratigraphic paradigm [PDF]

open access: yesJournal of Sedimentary Research, 2022
ABSTRACTSequence stratigraphy has the potential to provide a consistent method for integrating data, correlating strata, defining stratigraphic evolution, and generating quantifiable predictions. However, the consistent application requires a precise definition of concepts, stratigraphic units, bounding surfaces, and workflow.

Stratigraphic Classification: STRATIGRAPHIC COMMISSION

AAPG Bulletin, 1950
ABSTRACT The existence of the previously proposed categories of rock, time-rock, and time units is accepted. Stage and zone, which are customarily classified as time-rock units, are biostratigraphic or lithostratigraphic in character and therefore temporally transgressive.

From morpho-stratigraphic to geo-stratigraphic units: the PLANMAP contribution.

2021
<p>Geological units on Earth are defined by several parameters besides the stratigraphic ones, such as rock textures, lithology, composition, and environmental conditions of their origin (numerous and diverse magmatic, volcanic, metamorphic and sedimentary environments).

Proposal for Soil‐Stratigraphic units in the Australian Stratigraphic code

Journal of the Geological Society of Australia, 1970
Foreword The circumstances of the setting up of the Sub‐Committee for Soil‐Stratigraphic Nomenclature are set out in the introduction to the report which follows. A draft report prepared by the Sub‐Committee was considered by the Stratigraphic Nomenclature Committee at its meeting at Adelaide in August 1969. As a result of the decisions at that meeting

Stratigraphic models in exploration

Journal of Sedimentary Research, 1962
Abstract Stratigraphy has long been a descriptive science, rather than experimental, largely because of the great number and variety of variables involved. However, stratigraphic models can be constructed, based on the generalization that the shape of a body of sedimentary rocks varies as a function of the quantity of material ...

The Stratigraphic-Sedimentologic Data Base

1990
A successful basin analysis requires the collection and integration of several, perhaps many, different kinds of data. Direct observation of the rocks may or may not be fundamental to the study. In the case of a surface geological project, they will be preeminent, though perhaps supplemented by geochemical and geophysical information, plus laboratory ...
