  skos:definition "En géologie, un dropstone ou « bloc délesté » désigne un bloc isolé de taille variable, abandonné sur les sédiments fins du fond marin ou lacustre par la fonte d'un glacier, d'un iceberg, ou apporté sous forme de bombes volcaniques. (Adapté de : <a href=\"https://fr.wikipedia.org/wiki/Dropstone\">https://fr.wikipedia.org/wiki/Dropstone</a>)"@fr, "Dropstones are isolated fragments of rock found within finer-grained water-deposited sedimentary rocks. They range in size from small pebbles to boulders. The critical distinguishing feature is that there is evidence that they were not transported by normal water currents, but rather dropped in vertically through the water column. A  dropstone  is  a clast  of anomalous  size,  and/or lithology, indicative of vertical  or oblique introduction  into  a  host  sediment,  either  from  some  form of  raft,  or  as  a  projectile.  In  recent  years,  dropstones  have  become  firmly  associated  with  deposition  from  icebergs  and  sea  ice,  despite  the  fact that  other  possible  rafting  agents  are  well  documented  in  the  literature.
