AI Article Synopsis
- Osmium isotope ratios in marine sediments can help estimate the size of chondritic impactors based on research by Paquay et al.
- The study indicated that existing assumptions about how impacting projectiles behave after impact may require reevaluation.
- This is because a limited and variable portion of the impactor dissolves in seawater, complicating the assumptions made in the research.
Article Abstract
Paquay et al. (Reports, 11 April 2008, p. 214) reported that osmium isotope ratios in marine sediments can be used to determine the size of a chondritic impactor. Their assumptions on the fate of an impacting projectile may need to be reassessed, however, because only a small, unpredictable fraction of the impactor ends up dissolved in seawater.
