- Super Toba Eruption. Redefined the timing and magnitude of the first Toba Eruption (Sumatra) and suggested that such a super volcanic eruption did not cause any global cooling or glacaition (Lee et al., 2004).
- Active Volcano in NE Taiwan. Determined the age of the last eruption of Kueishadao, offshore, northeast Taiwan, and therefore pointed out that the volcanic activity of the southern Okinawa Trough is very recent – only 7000 years ago (Chen et al, 2001).
- Marine Tephrochronolgy. Established for the first time long-term records of volcanic eruptions of the LuzonIslands during the past 2 million years (Wei et al., 1988a, b). Identified the occurrence of volcanic ash in the South China Sea transported from the Youngest Toba eruption 71 thousand years ago (Lee et al., 1999, Song et al., 2000).
- Australasian Tektites. Lee and Wei (2000) revised the timing, location and magnitude of the big meteoritic impact on the IndochinaPeninsula that yielded the Australasisn strew field 790 thousand years ago. On the other hand, a 40Ar/39Ar dating of the tektites and impact glasses of the Darwin Glass in Australia demonstrated that the materials were formed by a meteorite impact at 807 ± 16 ka (Lo et al., 2002), coinciding with the ages reported for the Australasian tektites found in Southeast Asia and Australia (761-816 ka).
- Emeishan Basalt Trap. The coincidence in age of the eruption of Emeishan Flood Basalts and the Permian-Triassic boundary suggests that the eruption of Emeishan Trap, rather than the eruption of the Siberian Traps, was responsible for the global d13C excursion and mass extinction (Chung et al., 1998; Lo et al., 2002).
