(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 ...
-
(2006)Based on the geological data the authors collected in northern Xinjiang in the last two decades, together with a comprehensive analysis on the existent geological and geophysical data, they discussed the present-day crustal ...
-
(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 ...
-
(2006)The Bashkirian anticlinorium in the western slope of the southern Ural Mountains, Russia, exposes the poorly understood magmatic units of the southeastern margin of the East European craton. Volcanic and intrusive rocks ...
-
(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 ...
-
(2006)The suture zone between the Bhandara craton and the granulite-facies rocks of the Eastern Ghats Province in SE India contains a number of deformed alkaline and tholeiitic intrusives. The Khariar alkaline complex is one of ...
-
(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 ...
-
(2006)Major- and trace-element data on the constituent minerals of garnet peridotite xenoliths hosted in early Paleozoic (457–500?Ma) kimberlites and Neogene (16–18?Ma) volcanic rocks within the North China Craton are compared ...
-
(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, ...
-
(2006)The Paleo-Mesoproterozoic alkaline-rich intrusive rocks, mostly distributed in or near Yan-Liao triple-junction aulacogen system and Liao-Ji aulacogen along the north part of the North China Craton (NCC), are composed of ...
-
(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 ...
-
(2006)Giant porphyry Cu deposits were formed not only in continental- and island-arcs, but also in continent-continent collisional setting. However, the petrogenesis of ore-bearing porphyry associated with the continent-continent ...
-
(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 ...
