Sj. Xu et al., U-PB DATING OF ZIRCON GRAINS FROM THE ORE-BEARING PLAGIOCLASE AMPHIBOLITE IN THE DASHUIGOU TE DEPOSIT, Chinese Science Bulletin, 43(17), 1998, pp. 1486-1489
The Dashuigou Te deposit is a unique independent one found in the worl
d, and hosted in the plagioclase amphibolite. The upper intercept age
of single zircon from the amphibolite can be considered to be the crys
tallization age of the source-rock of the amphibolite (tholeiitic basa
lt), while the lower intercept is nearly consistent with the time of t
he tectono-thermal event.
