Les dépôts colluviaux ou colluvium sont constitués de débris de roches anguleuses, plutôt grossiers et presque sans stratification. Ils s'accumulent, par gravité, au bas des pentes abruptes. Ils forment quelquefois des talus et n'ont pas une grande importance. 6, record 1, French, - colluvion
Record number: 1, Textual support number: 2 CONT
Les dépôts colluviaux sont en général situés très près des matériaux détritiques, anguleux, sans stratification nette [...], peu classés, les débris les plus fins étant près de la surface et les plus grossiers en profondeur. Bien souvent maudits des géologues parce qu'ils masquent les affleurements, ils fournissent aux géomorphologues des renseignements précieux sur le processus d'évolution des versants. 4, record 1, French, - colluvion
