Abstract | Rock materials from three Arctic wells drilled through Middle-Upper Devonian basinal mudrocks between 1969 and 1973 were surveyed with the energy-dispersive X-ray fluorescence tool (ED-XRF) Bruker
Tracer IV-SD(TM). The logs of major oxides acquired from cuttings of two wells on Banks Island show that lithological signals can be seen through sample contamination, and therefore are capable of significantly increasing litho-chemostratigraphic
resolution of old borehole logs. Survey of major and trace elements on a cored section through visually monotonous black shales of the Kugaluk N-02 well in northern mainland N.W.T. reveals new details, which allows for the correlation of this
reference section with a better-studied succession in the central Northwest Territories, as well as the interpretation of anoxic horizons which correlate globally as the 'Devonian anoxic events'. Despite shortcomings in accuracy, ED-XRF proves to be
a rapid non-destructive technique to gain new information from old exploration wells in remote frontier areas. |
Summary | (Plain Language Summary, not published) Rock materials from three Arctic wells drilled through Middle-Upper Devonian basinal mudrocks in 1969-1973 were surveyed with the energy-dispersive X-ray
fluorescence tool (ED-XRF) Brooker Tracer IV-SD. The logs of major oxides acquired from cuttings of two wells on Banks Island show that lithological signals manifest through sample contamination, hence are capable to significantly increase
litho-chemostratigraphic resolution of old borehole logs. Survey of major and trace elements on a cored section through visually monotonous black shales of Kugaluk N-02 well in northern mainland N.W.T. reveals many new details, which allows to
correlate this reference section with better-studied succession in the central N.W.T. and interpret anoxic horizons that may correlate globally with the Devonian 'black-shale events'. Despite shortcomings in accuracy, ED-XRF proves to be an
excellent non-destructive technique to gain new information from old exploration wells in remote frontier areas. |
