Formation and Evolution of Chondritic Components

Chondrites are cosmic sedimentary rocks, consisting of materials formed in a wide range of temperature in the early Solar System.  Some chondritic components experienced thermal metamorphism and aqueous alteration on their parent bodies.  I do laboratory experiments and analysis of chondritic components to constrain the formation conditions of chondritic components both in the early Solar System and on their parent bodies.
