Installations and deposits
typologically by definition

Included here are stationary elements or features, which can be divided into

• installations that are set in place intentionally, and appear as either horizontal surfaces or as ordered aggregation, and
• deposits that can result either from either layering or buildup, or else from an amorphous amassment.

The main typological categories (surfaces, build-up, etc.) are listed according to types as defined in the pertinent section of the Grammar.
