A new combined rhenium-osmium- and platinum-group element data set for basalts from the Moon establishes that the basalts have uniformly low abundances of highly siderophile elements. The data set indicates a lunar mantle with long-term, chondritic, highly siderophile element ratios, but with absolute abundances that are over 20 times lower than those in Earth's mantle. The results are consiste...

The deep biosphere of the subseafloor basalts is recognized as a major scientific frontier in disciplines like biology, geology, and oceanography. Recently, the presence of fungi in these environments has involved a change of view regarding diversity and ecology. Here, we describe fossilized fungal communities in vugs in subseafloor basalts from a depth of 936.65 metres below seafloor at the De...

Olivine crystals in mare basalts 12004,8 and 12022,12 are normally zoned with Cr-poor rims. The Ni content of rare 2—10-jim metal inclusions in olivine decreases markedly as Fe/Mg in their immediate olivine hosts increases. Each metal grain appears to have been enclosed by late olivine almost immediately after it crystallized. The frac tionation trend for the olivine and metal contrasts with th...

Abstract In Pagondas and Kimi areas, central Evia Island, Greece, variably serpentinized ultramafic rocks of an ophiolitic origin are crosscut by rodingite dikes. Based on their protoliths, these rodingites distinguished into the following: (i) island arc tholeiitic dolerites, (ii) Mg-rich gabbros, (iii) alkaline basalts, (iv) calc-alkaline basalts. Rodingitization evolved in three successive p...

Introduction: The Lunar Magma Ocean (LMO) hypothesis holds that, early in its history the Moon was wholly or mostly molten [1,2]. Mafic minerals (olivine and pyroxene) crystallized first from the magma and sank to form the mantle, enriching the remaining magma in Fe and incompatible elements. Later, plagioclase floated in the dense Fe-rich magma [3,4], and concentrated at the Moon’s surface to ...
