In this presentation, I will review our current understanding of the formation and evolution of icy planetesimals. In particular, I focus on my recent work on understanding the composition and formation conditions of Ca-carbonates in CM chondrites (Telus et al., 2019, GCA). These minerals formed via direct precipitation from the fluid and\/or water-rock interactions in the parent asteroid. To understand the formation conditions of carbonates in CM chondrites, the C and O isotopic composition of Ca-carbonates and the O isotopic composition of magnetite were measured. I also discuss whether our data support current carbonaceous chondrite parent body models and how this work relates to current asteroid exploration missions.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Fall 2019 Talk: The Carbonaceous Chondrite Record of Icy Planetesimals Dr. Myriam Telus, University of California, Santa Cruz Friday, October 18, 2019 Atlas Talk: Noon, Tory 3-36 Meet the Speaker: 1PM, Tory 3-36 Abstract Carbonaceous chondrites show evidence for significant<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-101","post","type-post","status-publish","format-standard","hentry","category-speaker-series"],"_links":{"self":[{"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/posts\/101","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/comments?post=101"}],"version-history":[{"count":1,"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/posts\/101\/revisions"}],"predecessor-version":[{"id":102,"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/posts\/101\/revisions\/102"}],"wp:attachment":[{"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/media?parent=101"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/categories?post=101"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cms.eas.ualberta.ca\/gasi\/wp-json\/wp\/v2\/tags?post=101"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
