Most of the sedimentary fill of the Chiang Mai basin lies beneath a blanket of Quaternary floodplain deposits. |
Miocene-Pliocene volcanic rocks have a calc-alkaline character which gives way to a predominantly alkaline character in late Pliocene to Quaternary times. |
Hence, fundamental differences in the available datasets hinder an in-depth comparison of mid-Cretaceous with Pliocene to Quaternary black shale successions. |
Evidence for the young age of uplift and faulting includes juvenile topography, faulted Quaternary marine terraces and a fractured falaj. |
Historically, the Cenozoic has been divided up into the Quaternary and Tertiary sub-eras, as well as the Neogene and Paleogene periods. |
In fact, the whole idea of paleosols was first developed by geomorphologists and soil scientists to explore soils in the Quaternary. |
