Geochronology
(the age dating of rocks and minerals) is one of the most fundamental
fields in earth science because its application can provide constraints to
the timing of geological events and the evolution of the Earth and Solar
system.
In the past, it has been reported that there are quit a good number
of significant events happen in the region of Asia, for instances, mass
extinction, meteorite impact ... etc.
However, these have not been well studied before, especially the
timing of the events.
As one of the geochronology laboratories in this region, we are
also working on the age determination for these catastrophic events in
Asia. Publications:
