Abstract:

The research has been carried out to assess the rate of desertification of the karst ecosystem regarding land damage in the Darul Imarah, Aceh Besar District. This study aims to determine the level of damage to the karst ecosystem and its effect on water quality and to determine the condition of land cover in the Mata Ie karst ecosystem., Aceh Besar District. The data collection method used is using Landsat 8 satellite imagery to assess the level of damage to the karst ecosystem area. The assessment of water quality and quantity was carried out by means of a direct survey in the Mata Ie karts

Abstract:

This study includes a general description of the Earth’s karst types based on literary data and field observations. An improved classification of karst types distinguishes the main group, group, and subgroup; and, a division of karst types involves a main karst type, karst type, subtype, variety, and non-individual karst type. The relation between karst type and karst area is described. The role of various characteristics of karsts in the development of primary, secondary, and tertiary karst types is analyzed. Their structure is studied, which includes a geomorphic agent, process, feature, fea

Karst caves are among the most common and critical geological hazards in karst regions.

Karsts have developed on the surface of the Qingshuitang Wollastonite Mining Area in Huangtian Town, Hezhou City, Guangxi Province. In line with mine safety production requirements, a professional assessment of the potential development of karst caves must be conducted within 150 m of the mining area's surface.

The Tazhong area of the Tarim Basin contains abundant oil and gas resources in Ordovician carbonate rocks, especially in the karst pores and caves of the Yingshan Formation. Research has indicated that the Yingshan Formation underwent a 7–11 Ma exposure during the middle Caledonian Period, resulting in large-scale karst pores and caves. However, the continental freshwater karst model cannot adequately explain the origin and distribution of karst pores and caves. In order to develop a more accurate karst model to guide petroleum exploration in the region, we analyzed the karst morphology, cave

We evaluated an advanced forward-modeling-based reservoir characterization technique that uses full elastic finite-difference simulation to investigate the limits of karst identification in stacked seismic data. Identification of karsts is important for field development in carbonated reservoirs because paleokarst features can result in a loss of circulation and/or sometimes lost drill bits. Our primary objective was to verify whether we can detect and interpret the location and size of karsts from seismic data, especially given a complex overburden.

Despite more than 200 years of research on the shikhans, karst and its manifestations have received little attention to date.

Abstract:

Karst areas are landscapes composed of carbonate rocks and are rich in calcium and magnesium elements, making some macronutrients unable to be absorbed by plants directly. One of the soil microorganisms associated with plants in karst areas is Actinomycetes. Some species of Actinomycetes are known to produce growth hormones such as Indole Acetic Acid and dissolve phosphate bound in the soil. Actinomycetes also play an important role in soil ecosystems, especially in areas with extreme environmental conditions such as karst areas. Karst areas are known for their unique biodiversity and the pote

Abstract:

Karst is a rocky area that is known and categorized as an area with the title of natural beauty because of its unique shape, but it is rarely known to the wider community that karst areas hold a lot of potential and historical values, for example, the karst area in Maros- Pangkep that needs to be preserved. Preservation is considered difficult to realize because there are many mining permits for karst areas that exist for the manufacture of raw materials for cement and marble. Seeing the large number of people at large who do not understand what karst is and what its potentials are in it, the

As highways are extended to deep mountains, high altitudes, and special geological conditions, tunnel construction becomes more and more challenging, especially the construction of tunnels in karst areas. Due to the particularity of the regional geological structure, karst is well developed in the southwest of our country, especially at areas where the problem of tunnel water inrush in karst areas is more prominent. To further ensure the safe construction and operation of tunnels, the characteristics of tunnels in karst areas is analyzed in this article.

Abstract:

Geotechnical engineering in large scale is endangered by the karst areas which are close to the engineering. The stability of the tunnels is greatly affected by the sizes and locations of the karst caves. Based on a engineering example, a study of the effects of karst area beneath the tunnel on the stability of surrounding rock is conducted. It can be concluded that the displacement release of surrounding rocks and the distribution of the vertical stress in surrounding rocks are greatly affected by the sizes of the karst caves and the distance between the tunnel floor and the karst cave.
