Geology, Porcupine River (southeast), Yukon / [by] L.S. Lane. : M183-1/69-2012E-PDF
"The southeast quadrant of Porcupine River (NTS 116-J) has been mapped only once previously, during Operation Porcupine (1962-1976). The resulting reconnaissance map was issued in 1982 at 1:250 000 scale. This new preliminary GIS map and geodatabase, compiled at 1:50 000 scale, incorporates modern stratigraphic nomenclature, new biostratigraphic data and more accurately located structures and contacts based on air photo analysis, satellite imagery and up-to-date basemaps. Two extensive areas are underlain by very poor exposure. In the southeast, broad expanses underlain by Cody Creek Formation reveal little stratigraphic or structural information. Several structures that appeared on the original reconnaissance map in this area have yet to be corroborated. On the west side of the map, a large area was previously mapped as a broad pediment landform where underlying bedrock was largely unexposed. This map attempts to project the stratigraphy and structure beneath this poorly exposed area"--Abstract.
