Sedimentology Laboratory

  • images-departments-earth-icpnew-jpg

Spectro Ciros CCD with simultaneous spectrum measurement and wavelength range of 125nm to 770nm, with radial viewing capabilities. Purchased 2002. Carol B. de Wet, 2001, National Science Foundation Major Research Instrumentation grant, $ 123,695 for Inductively Coupled Argon Plasma Spectrometer.


F&M Students and faculty use on our Spectro Ciros inductively coupled plasma (ICP) spectrometer to perform elemental analysis for course and research projects. Students enrolled in Earth, Environment and Humanity, Geo 114, use the ICP lab to study the problem of lead and other heavy metal contamination in older systems. Students in Sedimentology and Stratigraphy, Geo 324, use ICP to study trace elements in calcite cements to better understand depositional and burial conditions.

Cathodoluminescent photomicrograph of same area showing dull luminescence in equant, porosity-occluding spar (upper right). Ooids are also brightly luminescent while quartz grains are non-luminescent under these operating conditions. Cathodoluminesce is used by students in the sed/strat. (GEO 324), Advanced Sed., ay courses and in faculty research.
