Abstract
This paper constitutes a personal vision of the carrier of Alfredo Bini, concerning the karstology. After his first period of sportive speleology, like a true scientist, Alfredo begins by geomorphological studies. He began a worldwide specialist in underground micromorphology. He studies the karstic areas around the Como Lake. But quickly, he develops his speleological science to the application in regional geology, for example by his participation in the Mediterranean Messinian crisis, in relation with the distribution of the karstic phenomena of the Lario region. During and after his thesis in geology, his target is the underground deposits. He works in the applications of underground deposits on paleoclimates and sismotectonics events. With those underground fillings, he brings elements to the reconstitution of palaeoenvironments, particularly in the alpine context. He becomes a specialist of the micromorphology of the detrital deposits, in particular using thin plates. The last great subject was the ghost-rock karstification. With his students, he proves that the karst of Lario comes essentially from ghost-rock. His last study in Valle Imagna is very rich in consequences on the regional and general geological and geomorphological evolution: digging of the valleys, altitudinal position of resurgences, karstogenesis.
