The John Day Formation is a series of rock strata exposed in the Picture Gorge district of the John Day River basin and elsewhere in north-central Oregon in the United States. The Picture Gorge exposure lies east of the Blue Mountain uplift, which cuts southwest–northeast through the Horse Heaven mining district northeast of Madras. Aside from the Picture Gorge district, which defines the type, the formation is visible on the surface in two other areas: another exposure is in the Warm Springs district west of the uplift, between it and the Cascade Range, and the third is along the south side of the Ochoco Mountains. All three exposures, consisting mainly of tuffaceous sediments and pyroclastic rock rich in silica, lie unconformably between the older rocks of the Clarno Formation below and Columbia River basalts above. (en) De John Day-formatie (Engels: John Day Formation) is een geologische formatie in de Amerikaanse staat Oregon, die een ouderdom heeft van Laat-Eoceen tot Vroeg-Mioceen (37 tot 20 miljoen jaar oud). De formatie bestaat voornamelijk uit vulkanisch gesteente als tufsteen, scoria en lava. De vulkanische gesteenten zijn meestal ryolitisch tot andesitisch van samenstelling. (nl) |
