Abstract

Sequence stratigraphy related to accommodation space as an area of potential sediment accumulation that is influenced by fluctuations in sea level and subsidence of the basin floor. Paleogeography, on the other hand, is the study of physical geographic features and their evolution throughout geological periods. The aim of this work is to shed light on the relationship between paleogeographic evolution and sequence stratigraphy, as well as coal accumulation in the South Sumatra Basin. The method used are geophysical logs and cores analysis to determine the system tracts, types of system tracts, and stratigraphic sequences, lithofacies and sedimentary facies analysis, paleogeographic analysis using modified single-factor and multi-factor and them mapped  using IDW as a geostatistical method. The results indicate that the study area comprises four system tracts, namely TST-1, HST-1, TST-2 and HST-2. In TST-1 and TST-2, the rate of peat formation is balanced with the rate of accommodation space formation, resulting in continuous and very thick coal accumulation. In HST-1 and HST-2, the rate of accommodation space formation exceeds the rate of peat formation, leading to continuous coal accumulation that is quite thick to very thick. Sequence 1 consists of lagoon and tidal/mouth/distal bar paleogeographic unit with  sand/shale ratio range 0.217 to 0.247. Sequence 2 consists of lagoon paleogeographic units with sand/shale ratio range 0.046 to 0.05.

Abstract

Lake Rayo in West Sulawesi, Indonesia, has been proposed as a potential meteorite impact structure, yet direct evidence supporting this origin remains limited. This study aims to provide a preliminary stratigraphic and granulometric characterization of Lake Rayo’s basin fill to clarify its genesis and support its geoheritage significance. Core sediment samples were collected from the basin floor and analyzed for grain size distribution, color (Munsell system), texture, and crack morphology using standard laboratory techniques. Seven stratigraphic intervals (BR1–BR7) were identified, showing clear vertical variations in granulometric parameters, sorting, and sediment color. Distinct fragmentation horizons, changes in color, and the occurrence of bedding cracks were interpreted as possible signatures of high-energy events, potentially associated with a meteorite impact. Comparative analysis with established impact structures, such as Lonar and Ries, revealed similar sedimentological features, supporting the impact hypothesis. These findings provide initial scientific evidence for the classification of Lake Rayo as an impact-related geoheritage site in Indonesia. The study also highlights the importance of integrating sedimentological data with future multidisciplinary research—such as geochemical and mineralogical shock analysis—to substantiate the impact origin more robustly. Overall, the results contribute valuable insights for geoheritage conservation, geoeducation, and the broader understanding of rare impact structures in Southeast Asia.

Abstract

This study assesses the geosite potential of two emerging geotourism locations Rayo Lake and Sosokan Waterfall in North Musi Rawas Regency using the Modified Geosite Assessment Method (M-GAM). The research aims to address the limited empirical application of M-GAM in developing geotourism regions of Indonesia, thereby filling an important methodological and regional gap. The assessment incorporates expert and visitor perceptions to evaluate Main Values (MV) and Additional Values (AV) across geological, educational, and touristic criteria. Field surveys and questionnaire-based evaluations were conducted with 22 experts and 55 visitors. The results show that Rayo Lake attained a high MV score and a moderate AV score, placing it in quadrant Z33, indicating strong geological significance supported by adequate visitor-related attributes. In contrast, Sosokan Waterfall was positioned in quadrant Z22, reflecting moderate performance in both MV and AV categories, primarily constrained by limited infrastructure and accessibility. These findings confirm that geological attributes alone are insufficient to elevate geosite readiness without parallel development of visitor-oriented facilities. The study’s novelty lies in providing the first M-GAM-based comparative assessment for geosites in North Musi Rawas, offering actionable insights for regional planning. Strengthening infrastructure, interpretive media, and accessibility is recommended to optimize geotourism development strategies.
