(2004)Geological and paleomagnetic data support the hypothesis that a Paleo-Mesoproterozoic supercontinent, referred to as Columbia, existed before the formation of Rodinia. This pre-Rodinia supercontinent was assembled along ...
-
(1998)Large submarine mud volcanoes in the abyssal part of the Black Sea south of the Crimean Peninsula are similar in many respects to synsedimentary mud volcanoes in the Mesoproterozoic Belt-Purcell basin. One of the Belt-Purcell ...
-
(2003)Mesoproterozoic marine successions worldwide record a shift in average delta(13)C values from 0 to +3.5parts per thousand, with the latter value evident in successions younger than 1250 Ma. New carbon isotope data from the ...
-
(2004)The Jaradag Fawn Limestone Formation (∼1.6 Ga, Semri Group, Vindhyan Supergroup, India) contains abundant microfossils and precipitates in early diagenetic (bedded and stromatolitic) cherts. The silicified carbonate ...
-
(2001)Thick, unmetamorphosed successions of siliciclastic and carbonate rocks in eastern and western Siberia preserve a record of Middle Riphean to Early Upper Riphean sedimentary environments and geochemistry. Consistent with ...
-
(2004)Paleogeographic reconstruction of the northern Siberian craton against southwestern Laurentia, in accordance with paleomagnetic data, basement piercing points, and the best fit of the rift margins, aligns Mesoproterozoic ...
-
(2003)The stratiform stromatolitic cherts from the Meso—Neoproterozoic Sukhaya Tunguska Formation (ca. 1,100–900 Ma) of the Turukhansk Uplift, Russia, preserve an abundant and varied record of ancient microbial life. The assemblages ...
-
(1994)Silicified shallow-water marine carbonate deposits of the Proterozoic Debengda Formation (the Olenek Uplift, northeastern Siberia) contain well preserved microfossils. One or two distinct assemblages consists only of ...
-
(2003)Molar tooth structures are abundant in large (1-2 m diameter) carbonate nodules within fine-grained, subtidal carbonates of the early Neoproterozoic (lower Upper Riphean) Burovaya Formation along the Sukhaya Tunguska River, ...
-
(2000)The Proterozoic connection between northeastern Siberia and western Laurentia that we proposed in 1978 is strongly supported by several new lines of evidence. New age data and refined structural trends in predrift basement ...
-
(2001)Recent efforts at supercontinental reconstruction for the late Precambrian (e.g., the SWEAT hypothesis Moores, 1991) have commonly invoked an uncertain lacustrine interpretation for deposition of the Mesoproterozoic ...
-
(2001)Preface Rodinia and the Mesoproterozoic earth–ocean system www.elsevier.com/locate/precamres We could hardly introduce this volume without mentioning the now infamous words of our respected colleague, Roger Buick, who, in ...
-
(2001)The latest Mesoproterozoic Burovaya Formation is a 600–1000 m thick stromatolite/mud dominated carbonate unit demarcated by an erosional unconformity into two subformations containing stromatolite reefs of variable size ...
-
THE MESOPROTEROZOIC BASEMENT IN THE SOUTHERN BALTIC SEA: INSIGHTS FROM THE G 14-1 OFF-SHORE BOREHOLE (2004)The continuation of the Mesoproterozoic basement of the southern Fennoscandian Shield is documented in the G 14–1 off-shore borehole, northeast of the island of Rgen, where crystalline rocks of monzogranitic composition ...
-
(2002)Arenites, wackes, and associated shales and siltstones of the Ui group of Riphcan age in southeastern Siberia have been analyzed for petrographic, major element and selected trace element compositions (including the REE). ...
-
(2005)Вдоль восточного края кратона Сан-Франсиску (КСФ) в Бразилии в пределах неопротерозойского подвижного пояса Арасуаи (районы Диамантина и Консейсан-ду-Мату Дентру) и в областях архейско- палеопротерозойских образований ...
