Debatable questions of Boreal Triassic stratigraphy: boundary between middle and upper series

Russian Geology and Geophysics, 2008
Abstract Various opinions on the position of the Middle/Upper Triassic boundary have been concisely reviewed. The lower boundary of the Carnian Stage is accepted at the base of the Trachyceras aon Zone. The recentmost data on biostratigraphy of boundary beds of the Ladinian and Carnian Stages of the Southern Alps, Himalayas, British ...

STRATIGRAPHY AND TECTONICS OF THE LATE CRETACEOUS - PLIOCENE SERIES IN THE NORTHWEST OF ANKARA(BAĞLUM - KAZAN)

1987
The series outcropped between Bağlum and Kazan towns in the northwest of Ankara are the sandstone rich flyschrepresenting the interval of Late Campanian - Maestrichtian, fluvial and limnic sediments of Paleocene epoch, shallow marinelimestones of Lutetiari age, and limnic and fluvial type continental series of Late Eocene and Mid Miocene period.

The stratigraphy and chronology of the Hawera Series marginal marine succession of the North Canterbury coast

1970
Hawera Series sediments of the coast of North Pegasus Bay are ideally suited for the study marginal marine stratigraphy and facies relations, and for examining the effect o the interaction of tectonic deformation and glacioeustatic sealevel fluctuation.
