Although Newberry Volcano has erupted magmas ranging from basalt to rhyolite in composition (Donnelly-Nolan et al., 2011; MacLeod et al., 1995), at the mafic end of this spectrum are primitive high-Mg basalts with major and trace element characteristics that include both tholeiitic and calc-alkaline varieties. At that time, it was not clear whether the solid solution was directly inherited from the parent rock, dominantly, a tholeiitic basalt, or was somehow formed during pedogenesis.

Plagioclase shows a characteristic change in the order of crystallization with water that may help to explain the formation of wehrlites intruding the lower oceanic crust (e.g., in Oman, Macquarie Island). They may, for instance, be compact, smooth, and glassy or porphyritic and can exhibit a wide range of colors, such as dark green, reddish brown, gray, or black. The tholeiitic andesite was probably extruded in a superheated condition with few crystal nuclei, and subsequent undercooling produced an unusual fasciculate/spherulitic texture in contrast to the very fine and even grain of the host basalt.

We catalogue and quantify the source strengths of the most probable electron donors and electron acceptors that would have been available to fuel early-Earth ecosystems. Throughout the process of igneous differentiation, the oceanic crust acts to reduce the magma, producing the tholeiitic trend.
