| Abstract | (Summary)
The lithostratigraphy of Eifelian-Frasnian strata in the subsurface of Mackenzie Valley, Peel Plain and Plateau between 64.5ºN and 68ºN is upgraded through revised formation tops in
126 exploration wells and rectification of formal and informal members within the Hume, Hare Indian, Ramparts, and Canol formations. In the westernmost part of the study area, insufficient resolution of legacy borehole logs is compensated by XRF
surveys of cuttings. The Horn River Group is considered equivalent to the Canol Formation of northwestern Peel Plain and Plateau and the adjacent Richardson Mountains. The lateral facies changes in these strata lead to the recognition of four
paleogeographic zones, each having a separate layout of member-rank traceable units. True vertical thickness (TVT) isopach maps and depth maps of selected units are created with Kriging methods in the ArcGIS Geostatistical Analyst wizard. |
| Summary | (Plain Language Summary, not published)
The Eifelian-Frasnian strata in the subsurface of Mackenzie Valley, Peel Plain and Plateau between 64.5ºN and 68ºN are receiving the upgrade in
lithostratigraphy involving revised tops in 126 exploration wells and rectification of formal and informal members within Hume, Hare Indian, Ramparts, and Canol formations. In the westernmost part of the study area, insufficient resolution of legacy
borehole logs is compensated by XRF surveys of cuttings. The Horn River Group is considered equivalent to the Canol Formation of northwestern Peel Plain and Plateau and the adjacent Richardsons. The lateral facies changes in these strata are
described by four facies zones, each having a separate layout of member-rank traceable units. True vertical thickness (TVT) isopach maps and depth maps of selected units are created with Kriging methods in the ArcGIS Geostatistical Analyst
wizard. |
