Limestone - Wikipedia
Limestone forms when calcite or aragonite precipitate out of water containing dissolved calcium, which can take place through both biological and nonbiological processes. [41] The solubility of calcium carbonate ( CaCO 3 ) is controlled largely by the amount of …
How Acidic Waters Make Rocks Disappear | Science Project
In this geology science project, you will investigate how acidic water can dissolve limestone rocks. You will do this by soaking several limestone rocks in acidic solutions and measuring the mass of the rocks over time.
Numerical simulation of mesomechanical properties of limestone ...
2022年12月1日 · In this study, the complex mechanical properties and mesoscopic failure behavior of limestone materials containing both dissolved hole defect and persistent joint, have been investigated through numerical modeling. Numerical models are developed using the PFC2D to carry out the uniaxial compressive strength tests.
11.10: Karst - Geosciences LibreTexts
Karst refers to landscapes and hydrologic features created by the dissolution of limestone. Karst can be found anywhere where there are limestone and other soluble subterranean substances like salt …
Study on the process of mass transfer and deterioration of limestone …
2024年3月4日 · A dynamic dissolution simulation experiment for limestone was constructed to investigate and analyze the variation patterns of the uniaxial compressive strength and elastic modulus of limestone...
Dissolution rates of limestones of different sources
2000年12月1日 · Accurately evaluating the dissolution rate of limestone is important in the development and the efficient operation of the SO 2 wet scrubbing system. The main constituent of limestone is calcite (CaCO 3). Many studies on the dissolution of calcite or limestone have been carried out so far.
Sources of limestone dissolution from surface water-groundwater ...
2024年9月5日 · Surface water-groundwater exchange enhances carbonate dissolution. Dissolution depends on residence time of recharged water in the subsurface. Carbonic, sulfuric, and nitric acids from subsurface reactions aid dissolution. Surface and subsurface acid sources can cause equal amounts of dissolution.
Solutional cave - Wikipedia
Limestone dissolves under the action of rainwater and groundwater charged with H 2 CO 3 (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as " karst ", characterized by sinkholes and underground drainage.
Micro-scale dissolution seams mobilise carbon in deep-sea …
2021年8月27日 · Here, we study diagenetic calcite dissolution in exhumed Paleocene deep-sea limestones from the Pahaoa river mouth, Wairarapa, New Zealand, to quantify how much carbon is mobilised by this...
Rain-induced weathering dissolution of limestone and ... - Springer
2022年9月19日 · This study estimated the extent of rain-induced weathering dissolution of limestone using hydro-chemical data from a karst area enjoying a subtropical monsoon climate, and proposed a mechanism of soil sinking and rock outcrops emerging, based on the assumption that the dissolved subsoil limestone is the main cause of geomorphic reworking of the ...
