  • Job Opportunity With Fugro Consultants

    Jordan Epstein '10 reports that Fugro Consultants, which specializes in geotechnical and seismic hazard consulting are currently looking for geologists. The possible work would involve drill rig logging, sampling, trenching, and mapping. Current project localities include Australia, Abu Dhabi, Idaho, Utah, and South Carolina. If you are interested contact Jordan at    

  • As I approach retirement – my successor Jonathon Cooper starts as our new Technical Director in a couple of days - I search for some profound and meaningful comment to make about my experience at Carleton over the past 36 school years.  But if I were a profound person I would have been a philosopher or a theorist rather than a technical director, so maybe I should just keep it simple.  I have enjoyed my work at Carleton immensely.  The place, the people, and the subject of geology have all been interesting and rewarding. 

    I am leaving the Carleton Geology Department in good hands, and I know that the faculty, Jon Cooper as the new Technical Director, Ellen Haberoth, and current and future students all will take good care of the Geology Department and help it thrive into the future.

    There is absolutely no question that the very best part of my experience in all these years has been getting to meet and work with well over a thousand wonderful people at Carleton. 

  • XRD Panalytical Empyrean machineWe are excited that our new x-ray diffractometer, funded by a National Science Foundation grant of $305,000, has been delivered and is now being readied for use.  In the picture, Cam Davidson (on the right) is being shown the innards of the beast by Panalytical installation technician Stephen Strong.

    Authors of the grant proposal were Melissa Eblen-Zayas of the Physics Department, Steve Drew, Chemistry Department, and Cam Davidson from the Geology Department.  The new machine is housed in the Geology Department and replaces the old XRD that dated from the late 1980s.

    X-ray diffraction has many uses in both geology and chemistry.  In geology, we often use it to identify minerals by crushing rocks into a powder and then running the powder through the machine.  The machine will analyze diffracted x-rays emanating from the sample and run the results through a database to find the mineral identities and relative abundance.

    From the proposal:  "X-rays have a wavelength that is comparable to the spaces between atoms in many materials. For this reason, x-rays can provide a powerful probe for exploring materials at a level that cannot be achieved with visible light, which has a much larger wavelength. This project will support the purchase of a multipurpose x-ray diffractometer to characterize a wide variety of materials, including materials that might be useful for various kinds of chemical and magnetic sensors and clays that can help us understand the climate history of southeast Alaska. In addition to enabling multidisciplinary research to promote our understanding of materials composition and structure, the XRD system will play an important role in training the next generation of scientists as it will be integrated into the curriculum as well as providing research experiences for undergraduate students in chemistry, geology, and physics at Carleton College."
