Stratigraphic correlation

In the research "Utilization of borehole data for correlation system of strata: A case study of Hanoi, Vietnam" the actual data of the investigation where the system was put into practice in order to estimate the subsurface structure of an area of approximately 7 km in length and 7 km in width in the city of Hanoi, using 275 borehole data, will be provided. In the stratigraphic comparison, the names of the Vietnamese soil types correspond to the Japanese soil types.

Ebook "Major impacts and plate tectonics: A model for the Phanerozoic evolution of the Earth’s lithosphere" presents evidence to show that impacts can cause significant and dramatic changes in track, which cannot be explained by current theories of plate tectonics. The book also demonstrates that such major impact events often coincide with the development of continental flood basalts and oceanic plateau basalts and frequently coincide with major stratigraphic stage boundaries and toxicity, which in turn can be associated with periods of extinction.

Tephras are significant markers in the stratigraphic record and play a key role in establishing paleoenvironmental and paleoclimate histories worldwide. Despite burgeoning research focused on tephra characterization and correlation techniques, there are still few techniques that allow for the direct dating of tephra, particularly below the lower age limit of K/Ar and Ar/Ar dating methods.

Lithostratigraphic units (formation, strata, and beds) and regional stages of the Oligocene-lower Miocene succession of southern Ukraine are described based on the results of comprehensive lithological and paleontological data analysis. The historical perspective on the stratigraphical investigations of the Maikop Group in the Crimean and Kerch Peninsulas and their equivalents in the broader Peri-Black Sea Region were also integrated in this overview.

This paper focuses on the correlation of two different marble units from an approximately 3,900 m deep geothermal exploration well (GP-1) in western Turkey by petrographical and geochemical data. Future geothermal exploration drilling in that area will benefit from a better (tectono) stratigraphic correlation and a better definition of the reservoir geometry in the basin. It is an innovative approximation in many settings to correctly correlate marble units without clear stratigraphic markers or fossil record, in particular, when sample material is restricted to cuttings.

This acoustic imaging has identified a canyon system at the slope and a shallow marine fan, which contains shelf incisions extending the İstanbul Strait incision. Multibeam bathymetry, ultra-high resolution seismic profiling and coring correlations on this subaqueous fan area allowed reconstruction of morphology and patterns of sediment distribution indicative of high energy sediment transport processes.

This sedimentological and sequence-stratigraphic study focuses on the late Miocene deposits in one of the largest periMediterranean basins of southern Turkey, the Adana Basin, which formed as a Tauride foreland depression accumulating molasse deposits. The Tortonian–Messinian shallow-marine Handere Formation, previously interpreted as a regressive succession, appears to have recorded several relative sea-level changes.

This report is based on fossil collections made over a vast area of the Canadian Arctic extending from Axel Heiberg Island in the north to the Aklavik region of the mainland and is a further contribution by the author on the Jurassic faunas of the Canadian Arctic. Detailed study of these ammonite faunas permits correlation of the associated Jurassic rocks and shows their faunal and stratigraphic relationships with Alaska, East Greenland, and the Arctic areas of Europe and Asia.
