WebApr 21, 2024 · 1. ^ [a] Early carbonate classification is grain-size based system: Calcilutite (grains < 63 μm), calcarenite (63 μm < grains < 2mm), calcirudite (grains > 2mm). 2. ^ [b] This family has restricted limits because cement by itself cannot form a rock and the supported framework component (allochems) has limited packing. WebDiamicton (or diamict) is a non-lithified diamictite (sediment). The definition above was proposed by Flint et al. in 1960 1 and it was meant to be and still is purely descriptive without any genetic connotations. This rock is sedimentary, it contains larger clasts in a fine-grained matrix-supported groundmass.
