This reminds that FST sets are structural whereas DM aggregates are structureless. The lahar (mudflow) deposits consist of conglomerates that occur in massive and structureless beds. It treats the liquids as dense structureless gases. The artificial and structureless background charge interacts electrostatically with itself and the electrons. Structureless hyaloclastite is commonly found in Archean felsic volcanic rocks. In such cases, the members of the type may be represented as structureless tokens.
