(1999)West of the Main Uralian fault, the main suture in the southern Urals, 40Ar/39Ar apparent ages of amphibole, muscovite and potassium feldspar are interpreted as cooling ages. A fast exhumation of the metamorphic complex ...
-
(2003)It has recently been found that Neoproterozoic glaciogenic sediments were deposited mainly at low paleolatitudes, in marked qualitative contrast to their Pleistocene counterparts. Several competing models vie for explanation ...
-
(2004)During the latest Neoproterozoic to Mid-Cambrian time (580–505 Ma ago), the Earth underwent significant changes in palaeogeography that included rifting of a possible supercontinent and the near simultaneous formation of ...
-
(2003)A runaway ice-albedo feedback at low latitudes has been proposed as an essential mechanism for achieving an ice-covered Earth. Previous simulations of the Neoproterozoic climate using a coupled ocean-atmosphere model have ...
-
(2007)The Central Asian Orogenic Belt is one of the largest accretionary terrains on Earth and records a ca. 800 Ma history of arc and microcontinent accretion, from south to north, during evolution and closure of the southwest ...
-
(2014)A study of U-Pb ages on detrital zircons derived from sedimentary sequences in the western flank of Urals (para-autochthonous or autochthonous with Baltica) was undertaken in order to ascertain/test source models and ...
-
(2001)In the last 1000 million years, Australia has been part of two supercontinents: Palaeozoic Gondwanaland and Neoproterozoic Rodinia. Neoproterozoic Australia was covered by shallow epicontinental seas, and, in the late ...
-
(2008)This new tectonic synthesis provides a framework for understanding the dynamic evolution of Baltica and for constraining tectonic correlations within the context of the Neoproterozoic break-up of Rodinia–Pannotia. Cryogenian ...
-
(1997)Original δ13C values of abiotically precipitated marine cements from a variety of stratigraphic intervals have been used to document secular variations in the δ13C values of Phanerozoic oceans. These, together with the ...
-
(2001)Carbon isotopic oscillations are useful to elucidate the stratigraphy and biogeochemical events around the Precambrian-Cambrian transitional beds across the Siberian Platform. The similarity of trends and amplitudes of the ...
-
(2001)The structure and tectonic position of the Neoproterozoic Central Taimyr accretionary belt of northwestern Siberia is dominated by the Faddey and Mamont-Shrenk granite-gneiss terranes, ophiolites, and back-arc volcanic ...
-
(2003)We have revisited the climate friction scenario during the Earth's major glacial episodes of the last 800 Myr: the Late Pliocene-Pleistocene $(~0-3 Ma)$, the Permo-Carboniferous $(~260-340 Ma)$ and the Neoproterozoic $(~750 ...
-
(2001)Mg-skarns enclosed in dunite cumulates of the Neo-Proterozoic Ioko-Dovyren intrusion (northern Baikal region, Russia) can be traced to silica-poor dolomitic host rock layers. The dominant minerals of the skarns are brucite ...
-
(1996)During the Neoproterozoic and Palaeozoic the two continents of Baltica and Laurentia witnessed the break-up of one supercontinent, Rodinia, and the formation of another, but less long-lived, Pangea. Baltica and Laurentia ...
-
(2002)We report major-element, trace-element and isotopic data of volcanic rocks from the late-Neoproterozoic (570 Ma) Agardagh Tes-Chem ophiolite in Central Asia, south-west of Lake Baikal (50.5N, 95E). The majority of samples ...

-
(1997)Sm-Nd, Rb-Sr and U-Pb isotopic systems have been studied in minerals and whole rocks of harzburgites and mafic cumulates from the Chaya Massif, Baikal-Muya ophiolite belt, eastern Siberia, in order to determine the ...
-
(1996)Synchronous occurrence of three large event borderlines at 1.100, 850, and 650 Ma in the Neoproterozoic is shown for the Siberian Platform in the northern part of the Central-Asian foldbelt and Chinese Platform. They ...
