Abstract

Carbonate rocks are one of the most important geological resources with a significant role in various industrial sectors, particularly as the main raw material in cement, lime, and construction industries. This study aims to review the characteristics, quality, and industrial potential of three major carbonate rock types—limestone, dolomite, and marble—based on relevant scientific literature. The research employed a literature review method using a qualitative-descriptive approach through analysis and synthesis of previous studies. Data were collected from scientific publications addressing the mineralogical, chemical, and physical aspects of carbonate rocks and their implications for industrial performance. The findings indicate that the quality of carbonate rocks is largely determined by mineral composition (calcite and dolomite), chemical purity (CaO and MgO), and the presence of impurities such as silica, alumina, and iron oxides. High-purity limestone rich in calcite is identified as the most efficient raw material for cement and lime industries due to its stable processing behavior and lower energy requirements. Conversely, dolomite with high magnesium content requires process adjustments to prevent excessive MgO formation during calcination. Marble, both in natural and waste powder form, shows promising potential as a supplementary material in sustainable cement production. Overall, this study emphasizes that understanding the mineralogical and chemical variations of carbonate rocks is essential for optimizing their processing strategies and promoting sustainable industrial utilization

Abstract

This research is located in the IUP area of PT Wijaya Karya Bitumen, C Block Kabungka Mine, Winning Village, Pasarwajo District, Buton Regency, Southeast Sulawesi Province. This study aims to classify asbuton trap rocks based on their chemical composition with XRF (X-ray fluorescence) and XRD (X-Ray Diffraction) analysis. The results of the XRF analysis showed that the asbuton trap rocks in the research area were dominated by CaO, MgO and SiO2 compounds. The CaO content varies between 24.56% to 44.46%. The SiO2 content in the samples varies, ranging from 7.81% to 12.54%. Three samples, namely TR1C-001, TR1C-002, TR1C-003 each contain MgO 0.57%, 0.85%, and 0.96%, while the other two samples, namely TR2C-001, TR2C-002 each contain MgO 14.40% and 17.51%, respectively. The results of XRD analysis showed three dominant minerals, namely Calcite (CaCO3), Quartz (SiO2) and Dolomite (CaMg(CO3)2). Based on the results of geochemical analysis (XRF and XRD) showed that the asbuton trap rock in the study area consists of 2 (two) types of carbonate rocks, namely Argillaceous Limestone with a CaCO3 content of 76.6% to 79.7% and slightly calcitic dolomite.

Abstract

In lateritic nickel mining, peridotite rock serves not only as the primary source of nickel laterite but also plays a crucial role in slope design and the development of mining infrastructure, such as the construction of mine roads. Additionally, economically non-viable peridotite can be repurposed as fill material or construction raw material if it meets specific technical criteria. This study aims to analyze the ripperability and abrasiveness of peridotite rock in the research area to determine the most effective excavation method. The analysis was conducted using joint spacing data and rock strength obtained through measurements of rock mass discontinuities using the scanline survey, uniaxial compressive strength (UCS) tests, and point load tests. The findings indicate that the rock in the study area can be classified into three main categories based on joint spacing and strength: easy ripping, hard ripping, and very hard ripping. Based on the analysis, the recommended heavy equipment includes Bulldozer models D7G and D8K, which are suitable for the rock rippability categories identified at the site. Rocks with high strength values exhibit high abrasiveness, leading to accelerated wear on heavy machinery. Therefore, selecting wear-resistant equipment and implementing more intensive maintenance planning are essential to improving operational efficiency in the study area.

Abstract

Facies analysis and thin-section petrography are complementary and essential approaches for determining the lithological characteristics of deep-water deposits. Deep-water sediments are formed by diverse depositional processes such as turbidity currents, debris flows, slumps, and pelagic suspension settling, producing a wide range of lithofacies with distinctive textural, compositional, and sedimentary structural attributes. This literature review synthesizes studies that apply facies analysis and thin-section petrography to characterize deep-water deposits across various basins and geological ages worldwide. Field-based facies analysis emphasizes lithology, sedimentary structures, bed geometry, and vertical–lateral facies relationships to reconstruct depositional environments. In contrast, thin-section petrography provides microscopic insights into mineral composition, grain texture, cement types, porosity, and diagenetic features that are not observable in the field. The integration of these methods, often combined with advanced techniques such as XRD, SEM, and geochemical analyses, has proven effective in distinguishing lithofacies, understanding sedimentary processes, and evaluating reservoir quality. The review highlights that grain size, sorting, cement type, pore-throat size, and diagenetic processes are key controls on lithological characteristics and reservoir potential in deep-water systems. Therefore, the combined application of facies analysis and thin-section petrography provides a comprehensive framework for interpreting deep-water sedimentary systems.

Abstract

Travertine is a non-marine carbonate rock precipitated from calcium- and bicarbonate-rich waters, commonly associated with hot springs, streams, and lakes in tectonically active regions. This study presents a systematic literature review of travertine deposit characteristics, encompassing mineralogical composition, geochemical signatures, petrographic textures, morphological types, isotopic properties, biotic–abiotic controls on formation, early diagenesis, and petrophysical implications. The synthesis indicates that travertine is predominantly composed of calcite, with aragonite forming under conditions of elevated temperature, high Mg/Ca ratios, and rapid CO₂ degassing. Travertines display exceptional textural diversity, ranging from abiotic crystalline crusts to microbially mediated fabrics such as shrub, peloidal, and stromatolitic structures. Major morphologies include fissure ridges, mounds, terraces, cascades, and slopes, strongly governed by tectonic setting, topography, hydrology, and substrate geology. Stable isotopes (δ¹³C and δ¹⁸O), strontium isotopes, trace elements, and REE patterns effectively constrain fluid provenance and distinguish thermogene from meteogene travertines. Microbial activity plays a crucial role in biomineralization, influencing precipitation rates, crystal morphology, and lamination patterns. Early diagenetic processes occurring during active deposition may significantly modify primary fabrics and geochemical signals. Travertine petrophysical properties exhibit distinctive porosity–velocity relationships, making them valuable analogues for subsurface carbonate reservoirs. This review highlights that travertines record complex interactions among physical, chemical, biological, and geological processes and hold significant value for paleoenvironmental reconstruction and carbonate reservoir studies.
