Shows

AAR analysis of solitary foraminifer may be used to figure out general age and correlate landscape features.

Robust, reworked foraminifera tests can help in understanding spatio-temporal habits of redeposition and erosion.

Formerly cibicides that are unanalyzed and Rosalina bradyi tests are been shown to be beneficial in geochronological applications.

Abstract

The recognition and correlation of a series of Pleistocene coastline barriers positioned inside the north Coorong Coastal Plain, Southern Australia, is created hard by long-lasting subsidence and reworking that is extensive. Associated shell beds, to all or any however the final barrier that is interglacial are subsurface rather than easily available. The whole-rock amino acid racemization technique had been discovered to be unsuitable for differentiating age distinctions of this specific obstacles as a result of the calcium that is low content associated with sediments, issues for the leaching or contamination as a consequence of the comminuted nature associated with shelly component, plus the possibly high content of reworked sediment.
