Karstic influence

Karst discovered and semi-discovered.

Collapses, falling blocks, formation of casimbas, caverns, sinkholes, sinkholes, etc., of large dimensions, Development of typical endo Karst and exo Karst such as mogotes, dog’s teeth, karst lagoons due to the collapse of caves and erosion of surface landforms. Subsidence of large tracts of land, well-developed karst areas.

Karst covered by a layer thin soil, it may also be assumed for areas with imminent carsick development when determining a high level of porosity and permeability in sedimentary formations.

Collapses, fall of blocks, formation of casimbas, caverns, sinkholes, etc., of considerable diameters, collapsed cliffs, typical karst of active tectonic zones with faulted or cracked areas favoring the action of groundwater in its degradation, etc. Differential subsidence. Developed karst areas.

Karst covered by potency deposits when there are very deep soils (>1 m. and sometimes more than 10 meters deep) and that

They generally do not have a direct genetic association with limestones.

Moderate collapses, formation of dog’s teeth, casimbas, caverns, etc., of reduced diameter, etc.

No karst, Scarce development of karstic forms, they only appear in isolation, very reduced endo Karst forms. Because it is considered as practically absent.
