TL;DR: In this article, the authors provided new constraints on the crystallization conditions of the 3.49 Ga Barberton komatiites and compared the compositions of pyroxene preserved in Barberton KOMatiites with pyroxenes produced in laboratory experiments at 0.1 MPa under anhydrous conditions and at 100 and 200 MPa (1 and 2 kbar) under H2O-saturated conditions on an analog Barberton composition.

TL;DR: In this article, the authors present both reviews and new research relating to the shared Gondwana origins of countries facing each other across the South Atlantic Ocean, especially Brazil, Argentina, Cameroon, Nigeria, Angola, Namibia and South Africa.

TL;DR: In this article, a model for the tectonic evolution of the Limpopo Belt must be based on the following data: crustal thickening to at least 65 km between ∼2700 and 2650 Ma ago was responsible for the formation of the granulite terrane exposed in the limpopo belt today, which probably resulted from the thrusting of the Kaapvaal Craton over the Zimbabwe Craton along the south dipping Triangle-Tuli-Sabi Shear Zone.

TL;DR: In this paper, a global geochemical dataset from one hundred-and-five greenstone sequences, ranging in age from the Eoarchean through the Archean and Proterozoic Eons, was examined to identify different ophiolite types (c.f. Zr) with distinct tectonic origins in the Precambrian rock record.

TL;DR: In this paper, the authors used the pre-fold palaeomagnetic data obtained from the Morondava Basin (SW Madagascar) of the late Cretaceous Period (approximately 83.6±1.6 Ma) to obtain the age of the Marion hotspot (46.0°S+5.3°S).
