Clara L. Blättler

Research interests:

I seek to understand the processes that shape the Earth's surface and marine environments and how changes in these processes have affected Earth history.  I use geochemical and isotopic tools to explore connections between the oceans, sediments, the rock cycle, and the climate system.  My work involves samples of many different ages (Archean through Recent) and from a broad range of locations and environments.  In particular, my research focuses on the sedimentary archives of carbonates (limestones and dolomites) and evaporites — these components of the geological record represent our primary means of understanding the ancient carbon cycle and seawater chemistry.

Active Projects:

  • Investigating carbonate diagenesis in the Maldives
  • Understanding the mineralogy of Cloudina and Namacalathus skeletons
  • Constraining Precambrian seawater chemistry
  • Understanding geochemical cycling during the Great Oxidation Event
  • Identifying diagenetic and mineralogical effects in the carbonate sedimentary record
  • Investigating Phanerozoic evaporite sequences
  • Quantifying crustal and seafloor recycling of carbonate
