WAVE-DOMINATED SHORELINE DEPOSITS IN THE LATE MIOCENE SEDIMENTARY SEQUENCE IN THE MIRI FORMATION NORTH SARAWAK, MALAYSIA
The research area is located in Miri region, north Sarawak. Observation was focused on selected outcrops along road cuts and beach. The distribution of outcrops is widely distributed at a few localities in Miri region such as Tanjong Lobang, Airport road, Hospital road and Oil Well road. Sedimenta...

description |
The research area is located in Miri region, north Sarawak. Observation was focused on selected outcrops along
road cuts and beach. The distribution of outcrops is widely distributed at a few localities in Miri region such as
Tanjong Lobang, Airport road, Hospital road and Oil Well road. Sedimentary sequences can be traced by facies
variations as shoreline environment based on the sedimentary structures. Four facies were identified and
characterised successfully in the study area based on their sedimentary structures, namely facies 1: planar cross
stratified (PcS), facies 2: swaley cross stratified (ScS), facies 3: swaley-Hummocky cross stratified (SHcS), facies
4: Hummocky cross stratified (HcS) and heterollithic facies (He). Facies evaluation deduced that the
sedimentation settings resulted as foreshore, upper shoreface, middle shoreface, lower shoreface and tidal
(minor occurrence). Wave-dominated in the upward coarsening interval is unambiguous that representing by
abundance of hummocky cross stratification and other storm deposits in the sandstone dominated portions,
well-defined swaley cross stratified sandstone interval, and up to several meters thick sets of planar cross beds
interval interpreted to have been formed by swash waves. Heterolithic units in this wave dominated sequences
are as minor occurrence of tidal influence during fair weather. |
