has part output of rock dust particulate environmental material aeolian transport process soot cryoconite deposit http://orcid.org/0000-0001-5812-6405 Do not oversimplify the particulate environmental material subclasses with design patterns or similar. The materials have properties that their components do not - write full definitions including these where possible. Particulate environmental material which is composed primarily of dust, rock, and soot, as well as the microbial communities associated with these materials, deposited on an ice mass by an aeolian process. http://orcid.org/0000-0002-3410-4655 envoPolar This actually is formed as a result of an accumulation process involving the constituents of cryoconite. When their semantics are more stable, we can axiomatise this fully.
