Comment:
These clastic (minerogenic) varves are formed by a discontinuous (highly seasonal) supply of suspended sediments, in this case glacial melt-water streams. The varves consist of laminae composed of coarse particles (sand, silt) and fine-grained (clay) laminae deposited in winter (winter layer).
