What Was the Initial O-Isotope Composition of Water Accreted by the CM Chondrites?
Suttle M. D.* METSOC 2026 abstract (PDF) “Numerical modelling (O-isotope perspective) shows CM chondrite alteration is best explained by isotopically light, TFL-like water (δ18O <30‰), moderate W/R (0.3-0.7), progressive heating (20-100°C), and pulsed dissolution. A…
