Waterflooded chalk (limestone) quarries have a fundamental similarity with natural limnic systems in their hydrochemical, bioproductive, and sedimentation processes (Axler et al., 1998, Khomitch, 2002b, Khomitch et al., 2012, Khomitch et al., 2013, Makarevich and Savich, 2014, Blanchette and Lund, 2016, Luek and Rasmussen, 2017, Jawecki et al., 2019, Kilonzo et al., 2019), and they also ...
Chalk
Chalk is a finetextured, earthy type of limestone distinguished by its light color, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or skeletons of plankton, such as foraminifera or coccolithophores. These fragments mostly take the form of calcite plates ranging from to 4 microns in size, though about 10% to 25% of a typical chalk is composed of ...
Chalk Sinkholes and Dissolution | Earth Science Partnership
Geologically induced, nonmining related subsidence is generally caused by the dissolution of calciferous or gypsiferous bedrock, such as limestone and the chalk bedrock which underlies much of the south and east of the UK. However, similar features can occur in other geological settings. Dissolution of the chalk or limestone takes place when ...

Limestone obtained from Upper Cretaceous rocks available in many areas of western Kansas is crushed and used mainly for road metal. A much softer stone than Pennsylvanian and Permian limestone units, the crushed limestone is often obtained from the Fort Hays Limestone and Smoky Hills Chalk members of the Niobrara Chalk Formation.

· Chalk mining methods have evolved throughout history as extraction techniques have improved, but they are also regionally variable, reflecting local conditions, available resources and demand. Mining styles have ranged from small, localised mines where chalk was extracted immediately around an entry shaft, to complex workings, stretching tens of metres below ground and consisting of .

Natural recolonisation by volunteer species of chalk and limestone quarries has led to the development of attractive and speciesrich communities in many parts of the United Kingdom. These communities have a basic similarity in floristic composition wherever they occur, but they also show a great deal of individual variation resulting from differences in the loion, history and variability ...
