The Green River Formation of the Uinta Basin in eastern Utah is host to not only one of the world’s largest oil shale deposits, primarily in the Mahogany oil shale zone, but it also contains significant conventional oil and gas reserves in interfingering sand bodies that grade into the laterally equivalent Colton and Wasatch Formations. However, very few marker beds and intervals can be correlated across the basin to help subdivide the 2 km-thick succession of upper Green River Formation strata overlying the main oil shale zone. This report forms part of an ongoing attempt to subdivide this sedimentary succession by identifying systematic variations in the abundance of particular elements, by way of inductively coupled plasma (ICP) spectrometry analyses, to produce a chemostratigraphy of the succession. This CD contains a 30-page report plus eight appendices.
