Palaeoproterozoic U-PbSHRIMP zircon age from basement rocks in Bangladesh: A possible remnant of the Columbia supercontinent
We present new U-Pb SHRIMP zircon geochronological data for basement rocks in Bangladesh, and discuss the relationship with the formation of the Columbia supercontinent. Euhedral zircons from a diorite sample yield a concordia age of 1730 +/- 11 Ma, which is interpreted as the crystallization age. T...
