Nannopaleontological Evidences at Paleogene and Neogene Boundary of Minbu Basin, Central Myanmar
The present research is emphasized on the some lithostratigraphic and nannoplankon biostratigraphic evidences between Paleogene and Neogene. The present study area is situated in the Minbu Township, Magwe Region. It lies in the north latitude (20°02´45"to 20°06´50"N ) and east longitude (9...
