Integrated Approach to Paleontological and Geochemical Data of the Upper Campanian–Maastrichtian Harami Formation (Elazığ, Eastern Türkiye)

The aim of this study is to determine the age and depositional environment of the Harami Formation through an integrated interpretation of XRF, ICP-MS, SEM-EDS, stable isotope, and radioactive isotope analysis results and findings of larger benthic foraminifera. Findings from the...

Density Structure of the Lithosphere in upper Priamurye

Abstract A 3D density model for the lithosphere of Upper Priamurye, which extends to a depth of 130 km, was constructed based on the anomalous gravity field. The lithospheric mantle displays a banded structure defined by a series of alternating relatively low and high density zon...

Age of Zircons from Sedimentary Rocks of the Elgon Formation of the Ulban Terrane on the Coast of the Ulban Bay

U–Pb dating of detrital zircons from sandstones of the Elgon Formation showed that the formation is no older than Oxfordian in age (early Late Jurassic) and not Middle Jurassic as previously assumed based on the rare flora and fauna finds and the position of the formation within...

Chemical Features of Rare-Earths Accessory Minerals in the Lower–Middle Cambrian Terrigenous Rocks from the Argun Series of the Northwestern Part of the Argun Superterrane as Indicators of the Sources

Abstract The paper presents the results of the chemical study of rare-earth accessory minerals of the Lower–Middle Cambrian terrigenous rocks of the Bystraya Formation and the Ernichny Unit of the Argun Series of the Argun Superterrane. The chemical analysis of monazite, xenotime...
