RESEARCH LAB

Dennis Darby

Microprobe and XRD Lab

• A Cameca SX100 electron probe microanalyzer with five spectrometers containing large diffracting crystals for enhanced detection plus EDS.
• A vacuum evaporator for coating samples.
• A Pan analytical X-Ray Diffractometer, model: Xpert Pro MPD

Sedimentology Lab

A fully equipped, modern lab for handling routine sedimentological investigations and sample preparation for microprobe analyses, including a large capacity centrifuge, high capacity sonifier, fume hood drying oven, computer-linked balance, 2 Nikon reflected-light pol-microscopes with cameras and one Vickers reflected-light ore microscope, several sets of sieves, and programmable Buehler polishing equipment.
