“…Heterolithic beds with planar and ripple lamination and non-channelised layers are typically found in a tidal environment such as tidal flats (Feldman and Demko, 2015;Quijada et al, 2016). Flaser lamination is also typically found in a tidal environment (Reineck and Wunderlich, 1968).…”

Clastic sediments of Oligocene to Lower Miocene age form a major thick and widespread sequence in the Tatau-Nyalau province of the north Sarawak Miri Zone. New light and heavy mineral data, U-Pb detrital zircon geochronology and biostratigraphy are used to identify the age, depositional environment, provenance and potential sources of sediment to reconstruct the drainage evolution of NW Borneo. Based on the biostratigraphic ages, depositional environments and provenance characteristics we modify previous stratigraphy and divide the Oligocene to Lower Miocene sequences into the Nyalau Formation (Biban Sandstone Member and Upper Nyalau Member), Kakus Unit, and Merit-Pila Formation. Two dominant source provinces were identified: the Malay-Thai Tin Belt which supplied sediments dominated by Permian-Triassic zircons, and the Schwaner Mountains of central Borneo which is identified by abundant Cretaceous zircons. Sediments either came directly, or were recycled from older sedimentary rocks, from these sources. The Sunda River deposited the Nyalau Formation during the Oligocene to Early Miocene with a dominant Malay-Thai Tin Belt source. The 2 Merit-Pila Formation of the Sibu Zone was deposited contemporaneously by a proto-Rajang River that drained Central Borneo (recycling the Rajang Group and Schwaner granitoids). Between c. 17 Ma the Sunda River system terminated and sedimentation was dominated by the northward prograding proto-Rajang River delta, depositing the Kakus Unit in the Miri Zone. This drainage system was active until the Late Miocene, before further uplift of Borneo terminated most sedimentation in the onshore part of present-day Borneo.

“…Testa & Bosence, ; Gläser & Betzler, ; Mata & Bottjer, ). Regarding tidal flats, there are good examples of both carbonate tidal flats (for example, modern: Andros Island, Rankey, ; ancient: Goldhammer et al ., ) and mixed clastic–carbonate tidal flats (for example, modern: the barrier island lagoon‐tidal system of Alsharhan et al ., ; ancient: Breda & Preto, ; Quijada et al ., ). However, there are no well‐known modern or fossil carbonate and mixed clastic–carbonate coastal areas potentially equivalent to clastic open‐coast tidal flats.…”

Facies model of a mixed clastic–carbonate, wave‐dominated open‐coast tidal flat (Tithonian–Berriasian, north‐east Spain)

Detailed logging and analysis of the facies architecture of the upper Tithonian to middle Berriasian Aguilar del Alfambra Formation (Galve sub-basin, north-east Spain) have made it possible to characterize a wide variety of clastic, mixed clastic-carbonate and carbonate facies, which were deposited in coastal mudflats to shallow subtidal areas of an open-coast tidal flat. The sedimentary model proposed improves what is known about mixed coastal systems, both concerning facies and sedimentary processes. This sedimentary system was located in an embayed, non-protected area of a wide C-shaped coast that was seasonally dominated by wave storms. Clastic and mixed clastic-carbonate muds accumulated in poorly drained to well-drained, marine-influenced coastal mudflat areas, with local fluvial sandstones (tide-influenced fluvial channels and sheet-flood deposits) and conglomerate tsunami deposits. Carbonate-dominated tidal flat areas were the loci of deposition of fenestral-laminated carbonate muds and grainy (peloidal) sediments with hummocky cross-stratification. Laterally, the tidal flat was clastic-dominated and characterized by heterolithic sediments with hummocky cross-stratification and local tidal sandy bars. Peloidal and heterolithic sediments with hummocky cross-stratification are the key facies for interpreting the wave (storm) dominance in the tidal flat. Subsidence and high rates of sedimentation controlled the rapid burial of the storm features and thus preserved them from reworking by fair-weather waves and tides.
