The hydrology of carbonaceous chondrite parent bodies and the evolution of planet progenitors

Oxygen isotope ratio data from carbonaceous chondrites are explained if aqueous fluids flowed from high to low temperatures within the parent objects of these primitive meteorites. Recognition of ancient hydrological activity on primitive asteroid precursors affords a new class of constraints on the heat sources (ages?) and sizes of planet precursors in the early Solar System based on the geolo...

Temperatures of Aqueous Alteration on Cm Chondrite Parent Bodies Based on Carbonate ‘clumped-isotope’ Thermometry

Introduction: Aqueous alteration of primitive meteorites was among the earliest differentiation processes in the solar system [1], and a better understanding of it would help constrain and test models of the thermal and chemical evolution of planetesimals. One of the challenges is to establish the temperatures of alteration. Petrographic analysis of CM matrices [2] suggest their temperatures of...
