Abstract
This paper describes the possible karst landforms observed in the Light Toned Deposits (LTDs) located within the Cagli crater, a medium size crater located in northern Sinus Meridiani, an area near the equatorial region of Mars.A morphological and morphometric survey of the LTDs surface morphologies through an integrated analysis of the available Reconnaissance Mars Orbiter (MRO) High Resolution Imaging Science Experiment (HiRISE) images highlighted the presence of shallow depressions that display different shapes and sizes.The Martian landforms were interpreted as sinkhole resembling similarly karst landforms that can be observed both in different karst terrains on the Earth and in other regions of Mars.The karst landforms observed highlight the evaporitic origin ofthese materials and suggest both climatic change and the presence ofliquid water, probably due to ice melting, during the late Amazonianperiod.
期刊介绍：
The Italian Journal of Geosciences (born from the merging of the Bollettino della Società Geologica Italiana and the Bollettino del Servizio Geologico d''Italia) provides an international outlet for the publication of high-quality original research contributions in the broad field of the geosciences.
It publishes research papers, special short papers, review papers, discussion-and-replies for their rapid distribution to the international geosciences community.
The journal is firstly intended to call attention to the Italian territory and the adjacent areas for the exceptional role they play in the understanding of geological processes, in the development of modern geology and the Earth sciences in general.
The main focus of the journal is on the geology of Italy and the surrounding sedimentary basins and landmasses, and on their relationships with the Mediterranean geology and geodynamics. Nevertheless, manuscripts on process-oriented and regional studies concerning any other area of the World are also considered for publication.
Papers on structural geology, stratigraphy, sedimentology, basin analysis, paleontology, ecosystems, paleoceanography, paleoclimatology, planetary sciences, geomorphology, volcanology, mineralogy, geochemistry, petrology, geophysics, geodynamics, hydrogeology, geohazards, marine and engineering geology, modelling of geological process, history of geology, the conservation of the geological heritage, and all related applied sciences are welcome.
