Biostratigraphic - definition of Biostratigraphic by The Free Dictionary
Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique. Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate. The regular order of the occurrence of fossils in rock layers was discovered around by William Smith.

A chronostratigraphic framework was developed as a prelude to a regional sequence stratigraphic and associated systems tracts analysis of the offshore Louisiana and Texas Miocene. The integrated data base for this study included over 10, line mi of seismic data, wireline logs, and detailed biostratigraphic analyses on 35 wells. The objective of the study was to map systems tracts and facies that may help delineate prospective areas. Because they are a fundamental stratigraphic unit within a sequence, this framework emphasizes condensed sections and their calibration by microfossil highest occurrence datums.
The study of the spatial and temporal distribution of fossil organisms, often interpolated with radiometric, geochemical, and paleoenvironmental information as a means of dating rock strata. All rights reserved. Copyright , , by Random House, Inc. References in periodicals archive?
