Interpreting Amalgamation Processes Of A Fluvial Sandstone Of The Nacimiento Formation In The San Juan Basin, New Mexico, Keely Elizabeth Miltenberger

Earth and Planetary Sciences ETDs

Outcrop studies of fluvial sand bodies are important for the study of fluid transport and storage capabilities because the deposits are heterogeneous. 3-D photogrammetry was used to evaluate the amalgamation processes of a multi-storey sheet sandstone in the San Juan Basin, NM. The Angel Peak member was deposited in the proximal-medial transition of a distributive fluvial system by a meandering river during the Paleocene. Within the study area, amalgamation occurred by avulsion and reoccupation of channel-belts to produce five storeys of the multi-storey sheet sandstone. Within each storey is evidence of processes that are internal to a channel-belt, such as …
