“…The mid-Holocene highstand is a phenomenon where regions distal from polar ice sheets experienced relative sea levels (RSLs) higher than present-day levels between 7000 and 4000 years ago (e.g., Woodroffe and Horton, 2005;Dutton et al, 2015;Kidson, 1982;Mitrovica and Milne, 2002). Mid-Holocene highstands of up to 5 m above present levels have been recorded globally in the Arabian-Persian Gulf (e.g., Al-Mikhlafi et al, 2021;Lokier et al, 2015;Mauz et al, 2022), South America (e.g., Angulo et al, 2006;Fontes et al, 2017;Milne et al, 2005), the Mediterranean (e.g., Mauz et al, 2015;Pirazzoli, 2005) as well as Japan (e.g., Yamano et al, 2019;Yokoyama et al, 2012). However, many of these regions experience significant tectonic deformation that generates additional vertical uncertainties (e.g., Yousefi et al, 2018).…”

The mid-Holocene sea-level highstand refers to the development of higher-than-present relative sea levels (RSLs) in far-field regions between 7,000 and 4,000 years ago because of equatorial ocean syphoning and continental levering. The timing, magnitude and spatial variability of the highstand are uncertain and the highstand parameterization in Glacial Isostatic Adjustment (GIA) modelling is understudied. Here, we use the RSL records of Southeast Asia to investigate the sensitivity of the mid-Holocene highstand properties to ice and Earth model parameters, including lithospheric thickness, mantle viscosity (both 1D and 3D), and deglaciation history of Antarctica and global ice sheets. We found that the Earth model variation only affects the magnitude of the mid-Holocene highstand unless low upper mantle viscosity is used. The timing of the highstand moves towards present and there is an absence of the highstand if upper mantle viscosity is <4.0 ×1019 Pa s or ≤1.0 ×1019 Pa s, respectively. Ice model variation changes both the timing and magnitude of the mid-Holocene highstand. Delaying the ice-equivalent sea level will shift the timing of the highstand later and result in a lower highstand magnitude. We produced a mid-Holocene highstand “treasure map” that considers topography change and accommodation space to guide future RSL data collection efforts in Southeast Asia. The highstand “treasure map” indicates the northern east coast and central west coast of Malay-Thai Peninsula, east coast of Sumatra, north coast of Java, and southwest coast of Borneo are very likely (90% probability) to preserve mid-Holocene RSL data.

The Depositional Record

In numerous carbonate reservoirs in the Middle East, peloidal packstone‐grainstones are rock types with excellent pore storage potential in micritised microporous grains. However, the origin of the micro‐porosity and associated micro‐spar remains unclear, and one hypothesis is that both micro‐spar and porosity originate from early marine micritisation and were later altered during subsequent diagenesis (i.e. cementation recrystallisation). The south‐eastern coast of the Arabian Gulf is recognised as a modern, albeit miniature, depositional setting analogue to Mesozoic carbonate sequences that form the supergiant reservoirs of the Middle East. Using optical microscopy, backscattered scanning electron microscopy and carbon and oxygen stable isotope analysis the present study aims to document the nature of internal microstructures of micritic envelopes and peloids from the surface sediments of various sub‐environments of the Abu Dhabi Lagoon. Results highlight a high degree of diversity and heterogeneities of most micritic envelopes and peloids observed across the sub‐environments. First, carbonate grains from ooid and bioclastic shoals show the simpler micritic envelopes. Here, micritic envelopes and peloids show sparse microborings filled with banded radial aragonite cement, a pattern of production of cryptocrystalline texture (e.g. micritisation) that is similar to the sequence of micritisation observed in the modern sediment of the Great Bahama Bank. Conversely, in the subtidal and intertidal zones with mangroves or seagrass, the micritic envelopes and peloids are much more complex and show multiple generations of microborings that are either empty or filled with carbonate materials of varying types (i.e. various cements, fragments, etc.).
