SEIlagerbildning

Could you clarify the context or field for "SEIlagerbildning"? The term isn’t widely recognized in standard references, and SEI can stand for different things depending on the discipline. Do you mean:

- a geological/sedimentological concept describing the formation of layered deposits (lagerbildning) in a setting associated with SEI (for example, a specific environment or acronym),

- a linguistic or terminological term in Swedish,

- or something else entirely?

If you have a source or more details (field, region, or intended meaning of SEI), I can draft a concise, neutral wiki-style article under 300 words.
