    • ‘The Pliocene is today defined as the later epoch of the Neogene period, between 1.8 and 5.3 Ma.’
    • ‘They reveal late Cretaceous and Neogene geothermal gradients that were comparable with that at the present day, i.e. no significant increase in basal heat flow.’
    • ‘The hole penetrated 366 m of Lower Pleistocene and Neogene hemipelagic deposits, and terminated in the uppermost Miocene.’
    • ‘The preserved Miocene sediments have allowed us to separate the effects of Palaeogene and Neogene uplift.’
    • ‘In contrast, the west side of the basin is marked by a relatively linear contact between uplifted Neogene sedimentary rocks and Quaternary alluvium.’
    1. 1.1The Neogene subperiod or the system of rocks deposited during it.
