Origin of the Cameroon Line of Volcano-Capped Swells

Swells of the Cameroon Line, a 1000-km-long line of 10 volcano-capped swells, resemble other volcano-capped topographic and bathymetric swells on the African plate. However, individual swells of the Cameroon Line are about 10 times smaller in area and distinct in being arranged in a straight line, half on the continent and half on the ocean floor. These peculiarities are here interpreted as rel...

Thermal modeling and organic geochemical appraisal of petroleum source rocks within the Aghajari Oilfield, SW Iran

Dezful embayment contains several potential source rocks deposited in tectonically active environments. Existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the Middle East. The Pabdeh Formation (Lower Paleocene-Eocene), the Gurpi Formation (Santonian-Masstrichtian), the Kazhdumi Formation (Albian) and the Gadvan Formation ...

Alkaline Rocks and Geodynamics

105 Abstract: Origin of A-type alkali feldspar granites is currently the subject of a world-wide debate. Contrasting hypotheses have been proposed, which range from an entirely crustal origin to an almost complete mantle derivation. A-type alkali feldspar granites belong to either unimodal granite (rhyolite)-dominated association, or bimodal gabbro (basalt)-granite (rhyolite) suite. It is argue...

Shock Thermodynamics of Mantle Rocks: Rockport Fayalite

Introduction. In order to address questions related to giant impacts and impact cratering on terrestrial planets, we need robust equations of state (EOS) and thermodynamic data for major mantle minerals (e.g., the olivine series and enstatite) and rocks under a wide range of pressure-temperature conditions. It is important to accurately characterize the amount of impact-induced heating that occ...
