Martian sub-surface ionising radiation: biosignatures and geology [PDF]

open access: yesBiogeosciences, 2007
The surface of Mars, unshielded by thick atmosphere or global magnetic field, is exposed to high levels of cosmic radiation. This ionising radiation field is deleterious to the survival of dormant cells or spores and the persistence of molecular ...

Icelandic analogs to Martian flood lavas [PDF]

open access: yes, 2004
We report on new field observations from Icelandic lava flows that have the same surface morphology as many Martian flood lava flows. The Martian flood lavas are characterized by a platy-ridged surface morphology whose formation is not well understood ...

Oxygen Isotopes and Volatiles in Martian Meteorite [PDF]

open access: yes, 2013
Oxygen isotopes were measured in mineral separates from martian meteorites using laser fluorination and were found to be remarkably uniform in both δ18O and Δ17O, suggesting that martian magmas did not assimilate aqueously altered crust regardless of any
