(2002)A study of clay mineral and calcareous nannofossil abundances in late Jurassic–early Cretaceous sediments from the Volga Basin, SE Russia, is presented. From these results, we are able to compare some general patterns of ...
-
(1989)While studying acritarchs from the Rudnyy Altay, we the authors discovered one cyst of a dinophyte alga whose structure provides evidence for its taxonomic membership in the order Dinophysiales. Morphologically, the cyst ...
-
(2003)Marine organisms have occupied hard substrates since the Archaean. Shells, rocks, wood and sedimentary hardgrounds offer relatively stable habitats compared to unconsolidated sediments, but the plants and animals which ...
-
(2002)The Grebenka flora, from the main exposure of the Albian–Cenomanian Krivorechenskaya Formation in northeastern Russia, represents a range of plant communities from pioneer to mature forest that grew close to the mid-Cretaceous ...
-
(Днепропетровский национальный университет им. Олеся Гончара, 2019)The aim of the study is the reconstruction of palaeoenvironments of the Middle and Early Upper Palaeolithic in the Upper-Tysa Depression, related to short-period Upper Pleistocene changes. Stratigraphical, palaeopedological, ...
-
(2015)As a case study, the Meihe Basin, a typical Cenozoic faulted basin, was divided into and identified as five three-order sequences by utilizing core, well logging, and seismic data, as well as palaeontological and geochemical ...
-
(2003)Southward drifting of the western Gondwanan margin during the Cambrian has been demonstrated by means of both palaeomagnetic methods and lithological indicators of climate (such as carbonates and evaporites). Recent ...

-
(2001)Yezupil is the first Middle Palaeolithic site discovered in upper part of the Dnister River valley. It is situated in a set of sediments composed of loess and fossil soils lying on alluvia. The results of geological and ...
-
(1995)The conventional corrections for bedding dip in palaeomagnetic studies involve either untilting about strike or about some inclined axis--the choice is usually governed by the perceived fold hinge orientation. While it has ...
-
(2002)Palaeomagnetic and rock-magnetic studies have been carried out for Cretaceous non-marine sedimentary rocks (Gongju Group) and volcanic rocks in the Gongju Basin, located along the northern boundary of the Ogcheon Belt, ...
-
(2003)Palaeomagnetic data are used to study the configurations of continents during the Proterozoic. Applying stringent reliability criteria, the positions of the continents at 12 times in the 2.45- to 1.00-Ga period have been ...
-
(2001)This paper presents a palaeomagnetic investigation in the Pamirs of Tadjikistan. Remanences are mainly carried by magnetite and are of secondary, synfolding origin. Application of a new method, the small-circle reconstruction, ...
-
(2001)A palaeomagnetic study of Vendian and Early Cambrian sediments from the Angara block of the Siberian platform: Shaman (52.08°N, 108.83°E) and Minya (58.0°N, 110.0°E) Formations, and the Tuva-Mongolian block: Tsagan-Olom ...
-
(2004)A detailed palaeomagnetic and magnetostratigraphic study of the Permian–Triassic Siberian Trap Basalts (STB) in the Noril'sk and Abagalakh regions in northwest Central Siberia is presented. Thermal (TH) and alternating ...
-
(2001)A preliminary palaeomagnetic and rock magnetic study was carried out on 248 Plio-Quaternary lava flows and three interbedded lacustrine sedimentary layers from Georgia (Caucasus). Most samples are characterised by a single ...
-
(2001)A palaeomagnetic study has been performed on Palaeo-Mesoproterozoic rocks from three crustal blocks of the Ukrainian Shield, southern Sarmatia. Primary remanent magnetizations have been isolated in 2.0Ga monzonite, 2.0–1.8Ga ...
-
(1996)Oriented samples of the Lower Cambrian Bayan Gol Formation from Salaany Gol, Mongolia, were collected at roughly 5 m stratigraphic intervals for palaeomagnetic analysis. Progressive alternatingfield and thermal demagnetization ...
