Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain karst landscapes and processes, describe landforms and regional types, relay hydrology, hazards and conservation from geoscience sources, and distinguish true karst from pseudokarst and thermokarst.

A landscape formed by the dissolution of soluble rocks such as limestone, dolomite and gypsum, marked by sinkholes, caves, disappearing streams, springs and underground drainage, with forms such as the cone karst or fengcong of southern China, tower karst and cave formations such as cave organs, and the analogous thermokarst of thawing permafrost; karst covers about a fifth of the land surface, supplies drinking water to a large share of the world population and is vulnerable to pollution and collapse.

What it is for: Not applicable; a landscape type.

It can be explain processes and landforms; describe regional types; relay hydrology and hazards; distinguish from pseudokarst.

Distinguishing features

Chemical dissolution

Underground drainage

Sinkholes and caves

Vulnerable aquifers

What it looks like

Rocky terrain with sinkholes, bare limestone pavements, caves and steep towers or cones in tropical forms.

Physical character

share of ice-free land: about 15-20 percent - estimates

population relying on karst water: about 25 percent - estimates

How it is recognised

Dissolution landscape in soluble rock

Sinkholes, caves, fengcong, tower karst, springs

Thermokarst forms by thawing ice; pseudokarst forms without dissolution

What the second pass must settle

  • Should thermokarst be a separate entry?
  • How should karst databases be linked?
  • The registry entry has merged aliases naming an analogous landscape and a cave feature; should they be split off?
