Bouma sequence graphic log
WebBouma cycles begin with an erosional contact of a coarse lower bed of pebble to granule conglomerate in a sandy matrix, and grade up through coarse then medium plane parallel sandstone; through cross-bedded sandstone; rippled cross-bedded sand/silty sand, and finally laminar siltstone and shale. WebRemember the Bouma sequence -- Ta (massive), Tb (planar bedded), Tc (current rippled), Td (planar laminated), and Te (suspension fallout only). These can vary in proportion, …

WebConventionally, the Bouma Sequence [Bouma, A.H., 1962. Sedimentology of some Flysch Deposits: A Graphic Approach to Facies Interpretation. Elsevier, Amsterdam, 168 pp.], composed of T a, T b, T c, T d, and T e divisions, is interpreted to be the product of a turbidity current. WebSince the Bouma paper of 1962 it has been demonstrated the turbidite deposit is a “member” of an evolutionary trend of vertically associated sediments that accumulate from debris flows, hyperconcentrated to concentrated density flows, and turbidity flows (Mulder & Alexander, 2001).
