Alphachron Applications

An increase in the number of research institutions around the globe utilizing uranium-helium thermochronometry for applications including mineral and petroleum exploration, geohazards assessment, and continental evolution studies, has prompted demand for a world-first technology developed by CSIRO Exploration & Mining and manufactured by ASI.

Uranium-helium thermochronometry is a highly sensitive and cost-effective method of radiometric age dating that can be used to determine the thermal history of the Earth’s crust. The major benefit of this technology to the mineral resources industry lies in the ability to quantitatively determine the low temperature thermal histories of mineral belts (see references below) and petroleum basins. This data is fundamental in the exploration for deposits of minerals, as well as oil and gas.
