The Logical Combination for Geoscience Analysis In response to requirements of university and industry partners, ASI developed with Curtin University a unique instrument with the capability to conduct U-Th-Pb-He triple-dating and trace element characterization of mineral chronometers. This instrument answers the needs of applications in basic geoscience research such as tectonics and landscape evolution studies, as well as for industry applications in petroleum basin analysis and mineral exploration.
Laser exploration ablation helium thermochronology samples a precisely defined, defect-free volume of the crystal, with a known surface area, thereby overcoming two uncertainties in the traditional method of bulk crystal measurement. Double dates are obtained quickly and at low cost in a compact instrument based on RESOlution and Alphachron™ technologies with well established heritage.

Advantages over Traditional (U-Th-Sm)/He methods
- Rapid dating of large numbers of mineral grains
- Negates the need for alpha correction (enables analysis of small grains)
- Negates the need for dangerous and time-consuming mineral dissolution (HF)
- Helium profiling
- Ability to avoid mineral/gas inclusions during analysis
- Increased precision and accuracy relative to traditional methods
- Provision of geochronology and thermochronology ages
- PLUS trace element analysis on single crystals
A RESOchron is the integration of:
- An Alphachron™ automated helium thermochronology system
- A RESOlution excimer 193nm laser ablation system including a Laurin Technic sample and UHV cells
- An ICP-MS system
- ICP-MS Compatibility
