Title: Core Sample from Uzon Caldera


1
Core Sample from Uzon Caldera
  • Elizabeth Hollingsworth
  • Clay Mineralogy

2
Environment of Yellow Blue Pool
  • Water chemistry
  • High content of dissolved Si, Na, Cl, SO4-2
  • pH 5.8
  • Eh - 225mv
  • Temperature 54C

3
Core Sample
  • Sub-sampled four horizons
  • 18
  • 19
  • 19a
  • 20
  • Distinct chemical gradient over small scale
  • Temperature
  • Eh
  • Bacterial influences

4
Trends in the Core
  • Opal throughout core
  • Sulfur abundant at top/gives way to pyrite as you
    increase in depth
  • Kaolin group mineral becomes more abundant with
    depth
  • Smectite is most abundant in the middle, but
    occurs throughout

5
Air Dried 18-20

What is Next
  • Use 060 to determine type of kaolin polymorph
  • Identify mystery peaks
  • Better characterized the smectite
  • Kelly/Green Method or other saturations
  • Use 060 for Di vs Tri
  • Continue to investigate possibility of mixed
    layering with Newmod
