DESCRIPTION:A mineral perspective on biominerals as recorders of trace elem
 ent and environmental signals\n\n \n\nMany organisms form their hard parts
  (skeletons\, shells) out of mineral-organic composites called biominerals
 . In aquatic settings\, as a shell or skeleton grows over time\, each new 
 layer traps the environmental conditions of the surrounding lake or seawat
 er (temperature\, chemical signals\, etc.) in the form of trace elements a
 nd isotope signatures. Paleoclimatologists depend on these biominerals and
  their proxy signals as recorders of past environments and as windows into
  the future. The mechanisms by which these biominerals form is a topic of 
 healthy debate and essential for understanding how these empirically-based
  trace element and geochemical proxies work\, yet\, relatively little has 
 been done to explore biominerals from a mineralogical perspective. In this
  seminar\, I will overview the work that my group has done to tie together
  trace element and oxygen isotope signals with crystal structure and cryst
 al bonding measurements in modern coral skeletons and mollusk nacre (mothe
 r of pearl). The goal is to better understand how organisms trap signals i
 n their minerals in order to assess the fidelity of paleoproxies and predi
 ct future biomineralization scenarios.
