Summary[edit]
| Description |
English: Basement Sill in the South Wall of the Wright Valley at Bull Pass in McMurdo Dry Valleys in Antarctica, intruding Late Ordovician age Granite Harbour basement rock. Chilled margins at the base (LZ) and layering in the central part of the Sill (Opx tongue) are visible. Note the emplacement style controlled locally by pre-existing basement fractures help create an undulating contact with country rock. From this perspective magma emplacement occurred E–W (left to right in the image) down a shallow 2–5° regional slope. |
