Microbial habitability of the Hadean Earth during the late heavy bombardment

  title={Microbial habitability of the Hadean Earth during the late heavy bombardment},
  author={Oleg Abramov and Stephen J. Mojzsis},
Lunar rocks and impact melts, lunar and asteroidal meteorites, and an ancient martian meteorite record thermal metamorphic events with ages that group around and/or do not exceed 3.9 Gyr. That such a diverse suite of solar system materials share this feature is interpreted to be the result of a post-primary-accretion cataclysmic spike in the number of impacts commonly referred to as the late heavy bombardment (LHB). Despite its obvious significance to the preservation of crust and the… Expand

Insights into the Hadean Earth from experimental studies of zircon
Geologists investigate the evolution of the atmosphere, crust, and mantle through time by direct study of the rock record. However, the Hadean eon (>3.85 Ga) has been traditionally viewed asExpand
The impact environment of the Hadean Earth
Abstract Impact bombardment in the first billion years of solar system history determined in large part the initial physical and chemical states of the inner planets and their potential to hostExpand
Geochemical constraints on the Hadean environment from mineral fingerprints of prokaryotes
New data on the elemental compositions and mineral fingerprints of both Bacteria and Archaea are presented, using these data to constrain the environment in which life formed, and suggests that the cradle environment of life may have been a weathering fluid interacting with dry-land silicate rocks.

Noachian and more recent phyllosilicates in impact craters on Mars
It is concluded that most phyllosilicates detected inside impact craters on Mars are consistent with excavated preexisting sediments, supporting the hypothesis of a primeval and long-lasting global aqueous environment. Expand
A new estimate for the age of highly-siderophile element retention in the lunar mantle from late accretion
Subsequent to the Moon’s formation, late accretion to the terrestrial planets strongly modified the physical and chemical nature of silicate crusts and mantles. This alteration came in the form ofExpand
Direct thermal effects of the Hadean bombardment did not limit early subsurface habitability
Abstract Intense bombardment is considered characteristic of the Hadean and early Archean eons, yet some detrital zircons indicate that near-surface water was present and thus at least intervals ofExpand
Could the Hadean Eon Have Been Habitable?
Given the absence of a macroscopic Hadean rock record, evaluating terrestrial habitability is largely a thought experiment, but data from Hadean zircons can provide some constraints. We are certainExpand
The Role of Meteorite Impacts in the Origin of Life
It is proposed that meteorite impact events are a fundamental geobiological process in planetary evolution that played an important role in the origin of life on Earth and should be considered prime sites in the search for evidence of past life on Mars. Expand
The Argyre Region as a Prime Target for in situ Astrobiological Exploration of Mars.
The astrobiological significance of some landscape features and terrain types in the Argyre region that are promising and accessible sites for astroBIological exploration are discussed. Expand
The Late Heavy Bombardment
Heavily cratered surfaces on the Moon, Mars, and Mercury show that the terrestrial planets were battered by an intense bombardment during their first billion years or more, but the timing, sources,Expand


Refugia from asteroid impacts on early Mars and the early Earth
Impacts of asteroids and comets posed a major hazard to the continuous existence of early life on Mars, as on Earth. The chief danger was presented by globally distributed ejecta, including transientExpand
Mass flux in the ancient Earth‐Moon system and benign implications for the origin of life on Earth
The origin of life on Earth is commonly considered to have been negatively affected by intense impacting in the Hadean, with the potential for the repeated evaporation and sterilization of any ocean.Expand
Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets
This model not only naturally explains the Late Heavy Bombardment, but also reproduces the observational constraints of the outer Solar System. Expand
The effects of heavy meteorite bombardment on the early evolution — The emergence of the three Domains of life
The interpretation of the molecular record suggests that life emerged early in Earth's history even before the time of the heavy bombardment was over, and the distribution of ecotypes on the rooted universal tree of life should not be interpreted as evidence that life originated in extremely hot environments.

Low heat flow inferred from >4 Gyr zircons suggests Hadean plate boundary interactions
An examination of over 400 Hadean zircons from Jack Hills is presented, which shows that some inclusion assemblages are conducive to thermobarometry, and it is suggested that the magmas from which the Jack Hills Hadeans zircon crystallized were formed largely in an underthrust environment, perhaps similar to modern convergent margins.

Submarine hydrothermal vents and associated gradient environments as sites for the origin and evolution of life
Submarine hydrothermal vents are the only comtemporary geological environment which may be called truly primeval; they continue to be a major source of gases and dissolved elements to the modernExpand
Thermal events documented in Hadean zircons by ion microprobe depth profiles
Abstract We report the first U–Th–Pb ion microprobe depth profiles of four Hadean zircons from the Jack Hills and Mount Narryer supracrustal belts of the Narryer Gneiss Complex (NGC), WesternExpand
Evidence for life on Earth before 3,800 million years ago
IT is unknown when life first appeared on Earth. The earliest known microfossils (˜3,500 Myr before present) are structurally complex, and if it is assumed that the associated organisms required aExpand
Lunar samples, lunar accretion and the early bombardment of the Moon
Recent advances in lunar sample science and planetary accretion theories demand a new look at the bombardment history recorded by the Moon. Among lunar samples there are no impact melts dated olderExpand
