EARLY CAMBRIAN DEPOSITS OF THE CONTINENTAL MARGIN (SOUTH OF TUVA, TEREGTIG FORMATION): RESULTS OF U–Pb DATING OF DETRITAL ZIRCONS AND Sr-CHEMOSTRATIGRAPHY

Доклады РОССИЙСКОЙ АКАДЕМИИ НАУК. Науки о Земле, 2023
The sedimentation interval (530–520 Ma) of the Teregtig Formation deposits in southern Tuva is estimated based on U–Pb dating of detrital zircons from terrigenous deposits and Sr-chemostratigraphy of carbonate rocks.

Chemostratigraphy Enables Correlations and Reservoir Characterization with High Resolution Elemental Data

Day 2 Tue, February 22, 2022, 2022
Previous studies have shown that by applying multivariate statistical analysis to chemostratigraphy, indistinct sequence stratigraphic correlations can be enhanced. Chemofacies and correlatable chemozones can be defined within highly homogenous strata,
