Microbial Populations of Stony Meteorites: Substrate Controls on First Colonizers
Finding fresh, sterilized rocks provides ecologists with a clean slate to test ideas about first colonization and the evolution of soils de novo. Lava has been used previously in first colonizer studies due to the sterilizing heat required for its formation. However, fresh lava typically falls upon older volcanic successions of similar chemistry and modal mineral abundance. Given enough time, t...
متن کاملThe origin and evolution of stony meteorites
The origin of stony meteorites landing on Earth today is directly linked to the history of the main belt, which evolved both through collisional evolution and dynamical evolution/depletion. In this paper, we focus our attention on the main belt dynamical evolution scenario discussed in Petit et al. (2001). According to Petit et al., during the planet formation epoch, the primordial main belt co...
متن کاملLow-temperature phase decomposition in metal from iron, stony-iron, and stony meteorites
The microstructure of the outer taenite rim and cloudy zone of meteoritic metal was investigated using high resolution scanning electron microscopy and analytical electron microscopy. The microstructure is formed by a series of complex phase transformations at ~400°C. These transformations are interpreted using the Fe-Ni phase diagram. The outermost subzone (zone 1) of the outer taenite rim is ...
متن کاملMagnetic Susceptibility of Stony Meteorites from the National Meteorite
Introduction: There has been recent interest in using magnetic susceptiblity to characterize and classify meteorites [1,2]. Measurements of magnetic susceptibility represent a fast, non-destructive and systematic way to categorize the rapidly expanding inventory of stony meteorites being discovered on Earth. Previous studies [1,2] have demonstrated that although magnetic susceptibility varies o...
متن کاملProbability sampling of stony coral populations in the Florida Keys.
Principles of probability survey design were applied to guide large-scale sampling of populations of stony corals and associated benthic taxa in the Florida Keys coral reef ecosystem. The survey employed a two-stage stratified random sampling design that partitioned the 251-km(2) domain by reef habitat types, geographic regions, and management zones. Estimates of the coefficient of variation (r...
