Facilities

Particle Size Laboratory 

  • Micromeritics SediGraph 5120 — uses x-ray monitored settling methodology and best for clay-rich sediments
  • Malvern Mastersizer 3000 (administered by Virginia Tech Geosciences faculty Dr. Tina Dura) — uses laser diffraction methods and best for coarse silt- to sand-sized sediment
  • sieves, drying oven, freeze-drying unit, analytical balance, and other accessories for processing of sediment

Sedimentary Microscopy Station

  • Leica DM2700P polarizing microscope and MC170 HD digital camera for petrographic (transmitted light) characterization
  • Leica S8 APO high-resolution stereo zoom microscope and MC120 HD digital camera for reflected light characterization of sediment samples
  • LAS image analysis and interactive measurement software

Trimble Differential GPS Surveying Equipment

  • GPS Pathfinder ProXRT Receiver
  • Trimble Nomad 900GL handheld
  • Laser Technology TruPulse 360B laser rangefinder

Computing Workstations for various software

  • Petrel — visualization and interpretation of 3-D geologic data
  • IHS Kingdom Suite — visualization and interpretation of subsurface data
  • ArcGIS
  • Agisoft Photoscan
  • Adobe CreativeCloud (Photoshop, Illustrator, etc.)
  • R, MATLAB, Python

Sedimentary Geochemistry lab

Little River Research & Design stream table

  • The Virginia Tech Museum of Geosciences includes an Em2 stream table that our group uses for teaching (e.g., laboratory activity in undergraduate Sedimentology-Stratigraphy course) and public outreach events
