17 Questions
What distinguishes peloids from ooids?
Peloids lack internal structures.
How are fecal pellets related to peloids?
Fecal pellets are a type of peloid.
Which process may lead to the formation of peloids?
Boring activities of endolithic algae on skeletal fragments.
What is the size range of peloids?
Silt to fine-sand size (0.03–0.1 mm).
