Introduction

Geologi dan pola sebaran batubara pada daerah kabupaten tabalong, kalimantan selatan. Kaji geologi dan pola sebaran batubara di Kabupaten Tabalong, Kalimantan Selatan. Analisis stratigrafi, struktur geologi, dan geomorfologi untuk referensi eksplorasi tambang efisien.

Abstract

Kabupaten Tabalong, Kalimantan Selatan, dikenal sebagai salah satu daerah dengan potensi batubara yang cukup signifikan di Indonesia. Penelitian ini bertujuan untuk mengkaji kondisi geologi dan menganalisis pola sebaran batubara di wilayah tersebut. Data yang digunakan meliputi peta geologi, geomorfologi, data struktur geologi, data singkapan, dan data topografi yang diperoleh dari PT Mahakarya Bangun Persada. Hasil penelitian menunjukkan bahwa daerah penelitian terbagi menjadi dua bentuk lahan, yaitu bentuk lahan perbukitan denudasional bergelombang lemah (D1) dan perbukitan vulkanik tersayat tajam (V1). Secara stratigrafi, wilayah ini terdiri atas tiga satuan batuan yang tersusun dari yang termuda hingga tertua, yaitu satuan batulanau, satuan batulempung, dan satuan batuan andesit. Struktur geologi yang berkembang di daerah penelitian meliputi antiklin dan kekar. Pola sebaran batubara di wilayah ini menunjukkan arah strike barat laut (northwest) dan dipping ke timur laut (northeast). Studi ini diharapkan dapat menjadi referensi dalam kegiatan eksplorasi dan perencanaan tambang batubara secara lebih efisien dan berkelanjutan. Tabalong Regency, South Kalimantan, is known as one of the areas with significant coal potential in Indonesia. This study aims to examine the geological conditions and analyze the coal distribution pattern in the area. The data used include geological maps, geomorphology, geological structure data, outcrop data, and topographic data obtained from PT Mahakarya Bangun Persada. The results of the study indicate that the study area is divided into two main landforms, namely weakly converted denudational hills (D1) and sharply incised volcanic hills (V1). Stratigraphically, this area consists of three rock units arranged from the youngest to the oldest, namely siltstone units, mudstone units, and andesite rock units.The geological structures that develop in the study area include anticlines and fractures. The coal distribution pattern in this area shows a northwest strike direction (northwest) and a slope to the northeast (northeast). This study is expected to be a reference in coal mining exploration and planning activities more efficiently and sustainably.

Review

The study, "GEOLOGI DAN POLA SEBARAN BATUBARA PADA DAERAH KABUPATEN TABALONG, KALIMANTAN SELATAN," presents a valuable investigation into the geological characteristics and coal distribution patterns within the Tabalong Regency. This region is recognized for its significant coal potential, making the research highly relevant for resource assessment and management in Indonesia. By systematically examining geological, geomorphological, and structural data, the study successfully delineates key features that influence coal occurrences, providing a foundational understanding essential for both academic insights and practical applications in the mining sector. A significant strength of this research is its comprehensive approach to data integration, utilizing various geological maps, geomorphological, structural, outcrop, and topographic data. This multi-faceted data acquisition, including information sourced from PT Mahakarya Bangun Persada, enhances the reliability and applicability of the findings. The clear identification of distinct landforms (denudational and volcanic hills) and major stratigraphic units, alongside the characterization of structural elements like anticlines and fractures, are crucial contributions to understanding the regional geology. Furthermore, pinpointing the northwest strike and northeast dip for the coal distribution pattern provides actionable intelligence for targeted exploration and efficient planning of future mining operations, aligning well with the study's stated objective. While the study provides a solid overview, the abstract could benefit from greater specificity regarding the geological context of the coal seams themselves. The described stratigraphic sequence (siltstone, mudstone, andesite) does not explicitly mention the primary coal-bearing formations or their associated depositional environments and ages. Clarifying this detail would significantly enhance the geological interpretation and the understanding of coal genesis in the area. Additionally, while the study effectively identifies the general distribution pattern, exploring the detailed relationship between the identified geological structures (anticlines, fractures) and their specific influence on coal seam continuity, thickness variations, or quality would further elevate its impact. Future research could build upon these findings by incorporating detailed stratigraphic logs or borehole data to quantify resource potential and provide a more robust basis for sustainable coal resource management.
