Background of Platform

It is an indisputable fact that geochronology plays a vital role in geosciences. However, the application and relevant research of experimental results were constrained because traditional dating methods required dissolving samples in chemical reagent, which made it hard for researchers to obtain all information of the structurally-complex zircon. With an irreplaceable advantage in testing ages of zircon, SHRIMP II ushered in a new age of micro-area and in situ analysis of zircon chronology, producing far-reaching influence worldwide.

We specialise in precise, accurate, high spatial resolution, uranium-thorium-lead geochronology of zircon, monazite, xenotime, titanite, allanite, columbite-tantalite, baddeleyite, rutile, cassiterite, opal, apatite, perovskite, gadolinite, chevkinite, ilmenorutile, uraninite and zirconite. A single collector ion probe doing in-situ U-Th-Pb age dating of zircon, monazite, xenotime and titanite in grain separates and thin sections. Just a few of the application areas are listed below.
