Statistical analysis was used to study the hydrogeochemical evolution of an Ordovician limestone aquifer group in the Hancheng mining area. Before mining, the groundwater flowed from northwest to southeast, the water type was primarily SO4–HCO3, and was mainly controlled by the tectonic structure and the specific hydrogeological …

Traditionally acid mine water is neutralised with lime (Ca(OH) 2 ) Limestone (CaCO 3 ) can be used as an alternative to lime as it is much cheaper. The aim of this study was to investigate the practicality of using cheaper limestone (CaCO 3 ) as an alternative. Beaker and semi-continuous studies were carried out to determine the …

This paper provides an overview of the engineering geology of limestone. Limestone is of rather wide occurrence in Malaysia. It is interesting in view of the unique landforms and karstic features that are encountered in limestone terrains, e.g. steep, subvertical limestone cliffs rising abruptly and majestically above the ground surface and highly …

Carbonate weathering by rain is considered to play an important role in the karst landform evolution. Rock outcrops (or stone teeth) are frequently visible on the earth's surface, especially in karst landscapes, but there is no consensus on how they appeared or increased in number. This study estimated the extent of rain-induced weathering …
