“…(3) Coordinates: international system; (4) Type (according to [51,58,60,83,84], distinguished on its geometrical characters in: (i) punctiform, small-size isolated single form or object (e.g., a sinkhole or a spring); (ii) linear, one or more simple forms developed preferentially in a single direction (e.g., a canyon, or a paleo riverbed) and/or stratigraphical sequences; (iii) areal: a set of large simple landforms related to just one type of genetic process (e.g., a karren field); (5) Lithology; (6) Genesis/main interest: e.g., tectonic, geomorphological, stratigraphic; regarding the geomorphological interest, a morphogenetic division related to a group of processes (coastal, fluvial, karstic, gravity-induced etc.) can be applied; (7) State of activity (e.g., [85][86][87][88][89][90][91][92][93]): active sites, those that allow the visualization of geological and geomorphological processes in action (e.g., fluvial systems); inherited sites defined as inherited landforms, which testify to past processes and have a particular heritage value since they are symbols of Earth's history and evolution (e.g., stack); (8) Brief geological and geomorphological description based on field observations and literature survey; (9) Documents, archive material and pictorial representations: e.g., photographs, sketches.…”
