Geological mapping was carried out in the outer part of Lesser Himalaya Barahakshetra – Tribeni area east Nepal along Arun River valley. A revised and updated tectono-lithostratigraphic scheme with detailed description each unit their comparison central west has been presented this work. The is divided into three tectonic units named as Chimra Thrust Sheet, Dharapani Sheet Paraautochthon from n...

Abstract We present a new magnetic compilation for Central Gondwana conformed to recent satellite model (LCS-1) with the help of an equivalent layer approach, resulting in consistent levels, corrections that have not previously been applied. Additionally, we use data its full spectral content, which helps include India, where high resolution aeromagnetic are publically available. As India is lo...

Changes in atmospheric carbon dioxide have been proposed as a major regulator of climate during the last 570 million years. Continental weathering and its variation over time are hypothesized to be important for controlling atmospheric carbon dioxide. Continental weathering is altered by changes in total runoff as well as changes in the size and elevation of the land masses to be weathered. Whe...

Permian red beds of the De La Cuesta Formation in the Sierra de Narváez (Paganzo Basin, northwestern Argentina) are essentially composed of sandstones associated with mudstones and subordinate conglomerates. Facies distributions and stacking patterns indicate that these sediments resulted from the interaction between aeolian and ephemeral fluvial systems, and are represented by aeolian dune, dr...

Two global-scale mantle convection cells presently exist on Earth, centred on upwelling zones in the South Pacific Ocean and northeast Africa: one cell (Panthalassan) contains only oceanic plates, the other (Pangaean) contains all the continental plates. They have remained fixed relative to one another for s 400 Ma. A transverse (Rheic^Tethyian) subduction system splits the Pangaean cell. Poloi...
