Jeff Taylor Course Introduction1 GG 673C: Petrologic Evolution of the Moon and Mars Course Introduction Why the Moon and Mars?

Jeff Taylor Course Objectives Present an overview of the petrologic evolution of the Moon and Mars Show that the same petrologic and geochemical processes operate on all silicate objects –But with differences due to object size, fO 2, bulk planet composition Explore processes involved in planetary accretion and differentiation To apply petrologic and geochemical tools to other worlds Course Introduction2

Jeff Taylor Learning Objectives Learn the general chemical compositions of Earth, Moon, and Mars Understand how we determine those compositions Get a quantitative understanding of the nature of planetary differentiation Recognize the styles of crustal evolution on Earth, Moon, and Mars Know the extent and chemical environments of weathering on Earth and Mars Course Introduction3

Jeff Taylor Course Introduction4 Why combine the Moon and Mars? We are really studying three planets.

Jeff Taylor Course Introduction5 Why combine the Moon and Mars? We know a lot about all three: –Samples –Remote sensing: Surface elemental concentrations Surface mineralogy Topography Gravity Seismology (Moon, nearside only) All are differentiated All important in understanding planetary accretion

Jeff Taylor Course Introduction6 Why combine the Moon and Mars? Three different sizes, hence three different thermal histories, different g, different atm Differ in amount of water: –Moon: some (hence no aqueous alteration) –Mars: quite a bit (hence a lot of aqueous alteration) –Earth: quite a bit (hence a lot of aqueous alteration) Differ in abundance of moderately volatile elements (K, Mn, P) and in volatile elements Moon and Mars are prime targets for human settlement

Jeff Taylor Course Introduction7 GG 673C Spring, 2016 Course Requirements Do all the reading assignments—before class Come to class and listen to pearls of wisdom—or at least listen to Jeff Participate in class discussions, including questioning above-mentioned pearls of wisdom (some of them might be slimy oyster goo instead) Take-home, open-book tests Two about the Moon 1-2 about Mars Lunar and Mars rock labs: Examine and describe thin sections of lunar samples and Martian meteorites, producing a written description of each rock. Can even put in pictures you take using the microscope. Also, new this year, a couple of quantitative XRD measurements of lunar regolith and a Mars simulant. Summarize for the class (5 to 10 minutes) at least one paper during the semester. Jeff will give everyone a paper, but feel free to find your own Has to be petrologic/geochemical GG 673C Spring, 2016 Course Requirements Do all the reading assignments—before class Come to class and listen to pearls of wisdom—or at least listen to Jeff Participate in class discussions, including questioning above-mentioned pearls of wisdom (some of them might be slimy oyster goo instead) Take-home, open-book tests Two about the Moon 1-2 about Mars Lunar and Mars rock labs: Examine and describe thin sections of lunar samples and Martian meteorites, producing a written description of each rock.
