1. Florida Center for Analytical Electron Microscopy, Florida International Univ. Miami, FL  Remotely Operable Research Instrumentation: Overcoming the “getting students to the machines” problem.  Routinely used in Astronomy for research and teaching.  Now Web technology has advanced enough that many different flavors of geoscience equipment can be remotely accessed.  The Analytical Instrument Registry: (http://serc.carleton.edu/NAGTWorkshops/petrology/instruments.html) lists geochemical instrumentation available for use. Some systems are remotely accessible.http://serc.carleton.edu/NAGTWorkshops/petrology/instruments.html  Remotely Operable Research Instrumentation: Overcoming the “getting students to the machines” problem.  Routinely used in Astronomy for research and teaching.  Now Web technology has advanced enough that many different flavors of geoscience equipment can be remotely accessed.  The Analytical Instrument Registry: (http://serc.carleton.edu/NAGTWorkshops/petrology/instruments.html) lists geochemical instrumentation available for use.

2. JEOL 8900 “Superprobe”: --Energy dispersive and Wavelength dispersive X- ray spectrometers, for quantitative chemical analysis of minerals. --Electron backscatter imaging. --Used to conduct micron-scale chemical studies of minerals in rocks.

3. JEOL JSM 5900LV Scanning Electron Microscope --Scanning electron and electron backscatter imaging --Up to 100,000x magnification (in “geologic” mode) --EDAX energy-dispersive X-ray spectrometer, for semi-quantitative chemical study

4. Samples are loaded by FCAEM technicians Telephone support and troubleshooting as needed during runs. Instruments are fully operable at a distance; only observed limitation is “tuning” the electron backscatter camera for varying electron reflectivity of minerals.

5. Field Relations, Geologic context (research literature…) Team Sample Selection/preparation and Microprobe/SEM characterization Handsample description and identification Term Projects: Petrologic Analysis Preparation and description of thin sections

6. To Learn more (and see how it really works): Come to Workshop Session II EH 316 2:30 – 4:30 PM Tomorrow! To Learn more (and see how it really works): Come to Workshop Session II EH 316 2:30 – 4:30 PM Tomorrow! Modeling Research Students work cooperatively to prepare samples (cutting, sectioning, polishing). Student “team” defines question(s) to address with SEM/microprobe data. Each student team gets time on the instrument: – EVERYBODY runs the machine.
