•Spreading out rock samples after a field season (organizing, examining, etc.)
•Powdering rocks for geochemical and isotopic analyses
•Preparing samples for various uses in rock physics, rock mechanics, geochemistry, energy studies
•Mineral separations for geochronology or geochemistry
•Purifying quartz for cosmogenic isotope studies
•Building simple equipment out of wood or plastic
The labs try to accommodate new equipment made available for School-wide use. Some of the lab rooms hold messy machinery that would be hard to tolerate in other labs. Please contact us if we ought to install something new. In some cases, we might be able to help fund it. In other cases, you'll need to fund it, but at least you won't need to find space for it.
•Processing those rare rocks with hazardous materials can be problematic. These include rocks with naturally occurring asbestos, mercury, other heavy metals, radioactive elements, hydrocarbon residues, etc. Contact us well in advance regarding this.
•If you don't have a well developed procedure for what you need to do, you will need to find one or develop one, which can be very time consuming. Again, contact us well in advance.
•Do not bring chemicals or hazardous waste into the labs without asking first.
