What does BFOF mean in UNCLASSIFIED
An acronym for Banner Formation Outwash Facies, BFOF is a term commonly used in geology to refer to the fluorescent layer of sedimentary rock located at the base of a river valley. This sedimentary rock contains a variety of minerals, such as quartz, feldspar and mica. Its coloration can vary from light pink to pale grey. The naming of the sedimentary formation originates from its resemblance to banners which have been waved in traditions by ancient cultures. BFOF formations are often found in areas where rivers have flooded, depositing sediments in large blocks that form ridges or “banner rings” on their banks

Essential Questions and Answers on Banner Formation Outwash Facies in "MISCELLANEOUS»UNFILED"
What is Banner Formation Outwash Facies?
Banner Formation Outwash Facies is an interbedded series of alluvial stratigraphy located in the southern Rocky Mountains, United States. This alluvial fill consists of braided outwash channels, overbank sediment, and plains sediment. It has a thick sequence of quartzitic sandstone, conglomerate and sand rich lithologies.
What age does Banner Formation Outwash Facies span?
Banner Formation Outwash Facies is thought to have formed during the late Eocene (34-40 million years ago) and extends up to the early Miocene (11-15 million years ago).
Where is Banner Formation Outwash Facies found?
The Banner Formation Outwash Facies are predominately found in the Colorado Plateau region in the southwestern United States including areas within Utah, Arizona, Colorado and New Mexico.
What type of deposits make up Banner Formation Outwash Facies?
Banner Formation Outwash Facies consists primarily of alluvial deposits derived from nearby fluvial systems. These deposits include interbedded cross-stratified channel sands, crevasse splay sands, sheetflood conglomerates, planar-laminated mudstone/sandstone alternating laminations as well as overbank elements such as reversely graded beds and horizontal thin bedding planes.
How did Banner Formation Outwash Facies form?
Banner Formation Outwash Facies was produced via long-distance fluvio-aeolian erosion which eroded primary Cretaceous rocks around present day Wyoming into its current position on the Colorado Plateau in the southwestern United States. Fluvial systems then carried these eroded sediments downslope delivering them into various depositional settings including fan deltas, braidplain outwashes, lacustrine environments as well as ephemeral pools or playas.
What evidence suggests that Banner Formatinon Outwasg Facies was formed by aeolian activity?
Evidence for aeolian activity can be inferred from the occurrence of quartzitic sands which indicate a source region with little to no vegetation cover which would help protect against wind deflation. Additionally, pebble imbrication patterns observed in clasts found within some facies suggest winnowing by strong winds.
:How thick are the deposits associated with Banner Formatinon Outwasg Facies?
The thickness of individual deposits vary greatly throughout this formation; however in general it is typified by a sequence that ranges between 200 - 300 m thick with an average thickness being 250 m thick overall.
