Glauconite is abundant in many Palaeogene rocks and its contained potassium can be used for radiometric dating. The methodology of this dating is described and sources of error and uncertainty are examined. Age determinations are presented on thirty-seven rocks mostly from NW Europe and these are discussed in relation to previous dating work. Ages are assigned to the boundaries of the Palaeocene, Eocene and Oligocene at 65, 52, 33 and 23 Ma respectively. Des progrés rècents dans la connaissance…

Glauconite dating of Palaeocene-Eocene rocks from East Kent and the time-scale of Palaeogene volcanism in the North Atlantic region
Glauconite dates obtained by conventional K-Ar and 40Ar/39Ar age spectrum techniques from Palaeocene horizons in Kent are examined against a Palaeogene K-Ar time-scale derived from the Tertiary
Jurassic to Paleogene: Part 2 Paleogene geochronology and chronostratigraphy
Summary We present a revised Paleogene geochronology based upon a best fit to selected high temperature radiometric dates on a number of identified magnetic polarity chrons (within the late
Genesis and Significance of Glauconitic Sediments of the Southwest Rockall Plateau
Glauconite-rich sediments have been encountered at two horizons during drilling in the southwest Rockall Plateau. The younger of these horizons lies at the base of a deep-sea ooze sequence and is of
Isotopic constraints on the genesis and age of autochthonous glaucony in the Oligo‐Miocene Torquay Group, south‐eastern Australia
The Oligo‐Miocene Torquay Group at Bird Rock in south‐eastern Australia comprises a sequence of fine‐grained skeletal carbonates and argillaceous and glauconitic sandstones, deposited in a
The Neogene: Part 2 Neogene geochronology and chronostratigraphy
Summary We present a revised Neogene geochronology based upon a best fit to selected high temperature radiometric dates on a number of identified magnetic polarity chrons (within the late Cretaceous,


Until recently, estjmates of the duration of geologic events in the earth's development were made exclusively by determining the age of minerals of intrusive rocks. This introduced a certain degree
Glauconites from New Jersey–Maryland Coastal Plain: Their K-Ar Ages and Application in Stratigraphic Studies
Glauconite samples from various stratigraphic levels in the northern Atlantic Coastal Plain were dated by the K-Ar method. Twenty-eight samples were collected from glauconite-bearing sands in four
Calcareous nannoplankton from early Tertiary rocks at Pont Labau, France, and Paleocene-early Eocene correlations
Well-preserved assemblages of calcareous nannofossils are found in Paleocene-early Eocene pelagic sediments on the north flank of the Pyrenees south of Pau, Basses Pyrenees, France. Nearly continuous
K-Ar-Ages of Eocene to Oligocene Glauconitic Sands from Helmstedt and Lehrte (Northwestern Germany)
Glauconitic sand at Helmstedt and Lehrte is covered by sediments yielding Lower Oligocene nannoplankton (zone NP 21). The sand is subdivided at both localities by phosphoritic pebble beds and at
Etude isotopique de l'altération naturelle d'une formation à glauconie (méthode à l'argon)
In Normandy (France), the glauconite bearing base of the Cenomanian has a wide distribution in outcrops and boreholes. Glauconite pellets are subjected to natural weathering and fluvial transport

Rb-Sr Study of Cretaceous Lobate Glauconite Pellets, North Carolina
Three glauconite samples were collected from the Rocky Point Member (Cretaceous, upper Navarro) of the Peedee Formation, below the faunal Mesozoic-Cenozoic boundary in the vicinity of Castle Hayne,
Reliability of Glauconite for Age Measurement by K-Ar and Rb-Sr Methods
Age measurements on glauconite by the K-Ar and Rb-Sr methods show a consistent variation with geological age with moderately small scatter. The results appear to fall 10-20 per cent short of ages

Potassium–Argon Dates and the Origin of Wealden Glauconites
GLAUCONITE grains are scattered through the arenaceous facies of the English Wealden (pre-Aptian Cretaceous). They become sufficiently abundant to form dark laminæ and beds of ‘greensand’ at two
