Unraveling the igneous and overprinting alteration histories of volcanic terrains on Earth and Mars

不同的火成岩、水蚀变和沉积过程影响着地球和火星上的火山岩和火山碎屑岩。作为加拿大航天局（CSA）支持的火星科学实验室（MSL）使命的参与科学家，我感兴趣的是区分这些过程的相对贡献，调查地球地质问题，也与了解火星的演变，包括火星地幔的特点和微生物生命的潜力。MSL Currency探测器遇到了一系列不同的岩性，包括演化的碱性火成岩、富含粘土的玄武质泥岩、砂岩和砾岩。补充陆地研究严重影响我们对这些岩石形成的环境和条件的解释。拟议的研究包括：

Diverse igneous, aqueous alteration, and sedimentary processes influence volcanic and volcaniclastic rocks on Earth and Mars. As a Canadian Space Agency (CSA)-supported Participating Scientist on the Mars Science Laboratory (MSL) mission, I am interested in differentiating the relative contributions of these processes for the investigation of terrestrial geologic problems that are also relevant to understanding the evolution of Mars, including the character of the Martian mantle and potential for microbial life. The MSL Curiosity rover has encountered a diverse suite of lithologies, including evolved alkaline igneous rocks, clay-rich basaltic mudstones, sandstones, and conglomerates. Complementary terrestrial studies critically influence our interpretations of the environment and conditions under which these rocks formed. Proposed research includes:
