New single crystal 40 Ar/ 39 Ar ages improve time scale for deposition of the Omo Group, Omo–Turkana Basin, East Africa
Open AccessIan Mcdougall, Francis H Brown et al.ARTICLEJournal of the Geological Society2012
Six tuffaceous beds within the Omo Group of the Omo–Turkana Basin have been dated using the 40 Ar/ 39 Ar single crystal total fusion method on anorthoclase, yielding eruption ages. The Omo Group constitutes up to 800 m of subaerially exposed sediments surrounding Lake Turkana within the East African Rift system in northern Kenya and southern Ethiopia. Rhyolitic explosive eruptions produced tuffs and pumice clasts that are considered to have been …

Geochronology of the Turkana Depression of Northern Kenya and Southern Ethiopia
Open AccessFrancis H Brown, Ian McdougallARTICLEEvolutionary Anthropology Issues…2011
Mesozoic and Cenozoic sedimentary rocks in the Turkana Depression of northern Kenya and southern Ethiopia rest on basement rocks that yield K/Ar cooling ages between 433 and 522 Ma. Proven Cretaceous strata are exposed in Lokitaung Gorge in northwest Kenya. Eocene basalts and rhyolites in Lokitaung Gorge, the Nabwal Hills, and at Kangamajoj, date between 34 and 36 Ma, recording the earliest volcanism in the region. Oligocene volcanic rocks, with …

Precise 40 Ar/ 39 Ar geochronology for the upper Koobi Fora Formation, Turkana Basin, northern Kenya
Open AccessIan Mcdougall, Francis H BrownARTICLEJournal of the Geological Society2006
The Plio-Pleistocene Koobi Fora Formation, about 560 m thick, crops out east of Lake Turkana and is part of the much larger depositional system of the Omo–Turkana Basin. The upper half of the Koobi Fora Formation from just below the KBS Tuff to above the Chari Tuff is particularly notable for its wealth of hominid fossils and archaeological sites. Silicic tuffaceous horizons have provided the basis for stratigraphic subdivision and correlation. P…
FxJj43: A window into a 1.5‐million‐year‐old palaeolandscape in the Okote Member of the Koobi Fora Formation, northern Kenya
Open AccessNicola Stern, Nick Porch et al.ARTICLEGeoarchaeology2002Cited by: 6References: 16
FxJj43 differs from most other archaeological sites preserved in the Okote Member of the Koobi Fora Formation in ways that make it especially suited to the problem of clarifying the behavioral information encapsulated in fine time‐lines. At this site in northern Kenya, a continuous strip of outcrops, preserving a set of interlocking landforms, can be traced around the modern erosion front for more than half a kilometer. The characteristics and th…

Evil Tongues’: A previously unedited Old English sermon
Open AccessDavid David, Ian McdougallARTICLEAnglo-Saxon England1997Cited by: 1References: 6
In his account of the contents of the second volume of London, British Library, Cotton Otho C. i, Kenneth Sisam drew attention to an unpublished sermon on the sins of the tongue to which he gave the title Evil Tongues . The sermon is written in the same hand as the two texts which precede it in the manuscript – an Old English version of St Jerome's Vita Malchi monachi captivi (henceforth Malchus ) and a translation of a letter by Boniface (Wynfri…

Serious entertainments: An examination of a peculiar type of Viking atrocity
Open AccessIan McdougallARTICLEAnglo-Saxon England1993References: 2
In a letter written to King Æthelred of Northumbria in or soon after 793, Alcuin bewails the appalling aftermath of the Viking attack on Lindisfarne. He writes, ‘vineam electam vulpes depredarunt, hereditas Domini data est populo non suo. Et ubi laus Domini, ibi ludus gentium. Festivitas sancta versa est in luctum.’ 1 Alcuin's horror at Viking merriment is shared by a great many other medieval historians in their accounts of the depredations of t…

The chronometric framework developed for Plio‐Pleistocene deposits of the northern Turkana Basin is reviewed in light of recent advances in lithostratigraphy, geochemical correlation, paleomagnetic stratigraphy, and isotopic dating. The sequence is tightly controlled by 20 precise ages on volcanic materials. These ages are internally consistent but are at variance with estimates for the boundaries of the magnetic polarity time scale by about 0.07…

Never, for example, do the authors discuss the substantial difficulties in determining whether a retina contains only rods, how many layers or types of a given cell class are present, whether all cells in the amacrine cell layer are amacrines, etc. The…
Canada's Oil and Gas: An 'Eleventh Hour' Option That Must Not Be Ignored
Ian McdougallARTICLECanadian Public Policy1975
Canada has consistently underpriced its exports of energy resources and overstated its capacity to export them. The rapid depletion of the conventional reserves of petroleum and natural gas promises a crisis for future Canadian economic growth and stability that may prove to be of unheralded proportions. At the time of writing, Canadian policy makers have a very brief period during which it may yet be possible to contain the dimensions of the pro…
