Abstract
Existing terminology of till-like sedimentary deposits tends to emphasize genesis without considering all possible modes of origin and to suggest relationships to tillite that may be erroneous. Therefore new terms (symmicton for sediment; symmictite, for lithified equivalents) are proposed as general names for essentially nonsorted, noncalcareous, terrigenous deposits composed of sand and/or larger particles in a muddy matrix.
