This chapter provides an overview and key references of glacial processes and resulting sedimentary products in subglacial, terrestrial proglacial and glaciomarine or glaciolacustrine settings. This information will enable the readers to identify features that may be used in identifying the signature of glacial influence in ancient deposits. The chapter also outlines some of the important issues that require consideration when making palaeoclimatic reconstructions from Neoproterozoic sedimentary successions. A summary table outlining the characteristics of diamictite with different depositional origins is also included in order to assist with the interpretation of the Neoproterozoic sedimentary record.
