Meteoritic evidence for very early volcanism in the nascent solar system

Scientists from Freie Universität Berlin, University of Bristol, Northwest University Xi'an and the Institute of Geochemistry of the Chinese Academy of Sciences have published the results of a new determination of the crystallization age of 4566.6 ± 0.6 million years for a meteorite called Erg Chech 002 (EC 002). The new age, determined using the manganese-chromium dating method, shows this rock crystallized only 0.7 ± 0.6 million years after the formation of the solar system.

Long-term preservation of Hadean protocrust in Earth’s mantle

Due to active plate tectonics, there are no direct rock archives covering the first ca. 500 million y of Earth’s history. Therefore, insights into Hadean geodynamics rely on indirect observations from geochemistry. We present a high-precision 182W dataset for rocks from the Kaapvaal Craton, southern Africa, revealing the presence of Hadean protocrustal remnants in the Earth’s mantle. See full publication here .
