Accretionary orogens are considered major sites of formation of juvenile continental crust. In
the central and southern Andes this is contradicted by two observations: siliciclastic fills of …

Abstract The Meso-Neoproterozoic period, sometimes referred to as the 'boring billion'or
'Earth's middle age', spans the interval between the formation of the Columbia and Rodina …

Palaeomagnetic apparent polar wander (APW) paths from the world's cratons at 1300–700
Ma can constrain the palaeogeographic possibilities for a long-lived and all-inclusive …

This paper examines the extensive regions of Proterozoic accretionary belts that either
formed most of the Amazonian Craton, or are marginal to its southeastern border. Their …

Possible large-scale geological correlation between Baltica (East European Craton) and
Amazonia (central South America) is discussed using compilations of recent data and …

Outcrops of late Meso-to early Neoproterozoic crust in northwestern South America are
restricted to isolated exposures of basement inliers within the northern Andes of Colombia …

The late Mesoproterozoic was a time of large-scale tectonic activity both in the interior and
on the margins of Laurentia—most notably the development of the Midcontinent Rift and the …

The West Amazon Craton consists of rocks of the Sunsás Orogen and the Rondônia-
Juruena Province. The Sunsás Orogen comprises the western part of the Amazon Craton in …

In recent years, a rapidly expanding database, especially in sensitive high-resolution ion
microprobe (SHRIMP) geochronology, has led to significant advances in understanding of …

Neoproterozoic Palaeogeographic reconstructions of Rodinia conventionally place the
western (Proto-Andean) margin of Amazonia against the eastern (Appalachian) margin of …
