Argon gas extraction at NMGRL is accomplished either by resistance furnace or CO laser heating.
The chemical name of zircon is zirconium silicate and its corresponding chemical formula is Zr Si O.
Zircon is a common accessory or trace mineral constituent of most granite and felsic igneous rocks.
Every discipline that benefits from geochronology should participate in the stewardship and development of this field, including scientific efforts and financial support.
In return, geochronologists must address the research priorities of the disciplines they support and provide enhanced user access to data.
Due to its hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.
Zircons contain trace amounts of uranium and thorium and can be dated using several modern analytical techniques.
Congratulations to Susie on the well-deserved citation! Bill Mc Intosh and Matt Heizler who have over 30 years combined experience in the field of argon geochronology and thermochronology.
The lab also employs a full-time technician, Lisa Peters who supervises mineral separation, sample irradiation and analyses and data reduction.
Al Deino at the Berkeley Geochronology Center in Berkeley, California which allows for full automation of extraction line and mass spectrometer functions .
