Earth's earliest evolved crust generated in an Iceland-like setting
It is unclear how the earliest continental crust formed on an Earth that was probably
originally surfaced with oceanic crust. Continental crust may have first formed in an ocean …

Fungus-like mycelial fossils in 2.4-billion-year-old vesicular basalt
Fungi have recently been found to comprise a significant part of the deep biosphere in
oceanic sediments and crustal rocks. Fossils occupying fractures and pores in Phanerozoic …

The geochemistry of loess: Asian and North American deposits compared
DR Muhs - Journal of Asian Earth Sciences, 2018 - Elsevier
Loess is widely distributed over Asia and North America and constitutes one of the most
important surficial deposits that serve as terrestrial records of the Quaternary. The oldest …

Microbial diversity on Icelandic glaciers and ice caps
Algae are important primary colonizers of snow and glacial ice, but hitherto little is known
about their ecology on Iceland's glaciers and ice caps. Due do the close proximity of active …

Carbon isotope and abundance systematics of Icelandic geothermal gases, fluids and subglacial basalts with implications for mantle plume-related CO2 fluxes
We report new carbon dioxide (CO 2) abundance and isotope data for 71 geothermal gases
and fluids from both high-temperature (HT> 150° C at 1 km depth) and low-temperature (LT< …
