Journal Article
Published: 29 May 2020
Quarterly Journal of Engineering Geology and Hydrogeology (2020) 53 (4): 645–654.
...T.G. Newman; R.C. Ghail Abstract Laboratory experiments have been performed to demonstrate significant levels of oxygen depletion within samples of Upnor Formation of the Lambeth Group deposits. These have been used to explain the reasons for several incidences of confined space hypoxia during...

...T. G. Newman; R. C. Ghail; J. A. Skipper Abstract Deoxygenated air poses a serious, life-threatening hazard (confined space hypoxia) for engineering projects in London, particularly within the Upnor Formation of the Lambeth Group. This paper reviews its causes and postulates that it was induced...

... that exactly honours geologists’ interpretations of the data. The data are used in their true 3D position. The 3D model of faulted Lambeth Group (Palaeogene) strata in the area of the proposed new Crossrail Farringdon underground station, in central London, has several types of benefit. These include allowing...
