kärnytor

Kärnytor (Swedish for "core surfaces") is a term used in several technical contexts to describe a surface that bounds or relates to a central or core part of an object. Because it is a compound, its precise meaning varies by field and is not a single standardized concept.

In geology and geotechnical practice, kärnytor often denotes the outer surface of a core sample that has been extracted from rock or sediment. This surface marks the boundary between the interior material of the core and the surrounding environment and is commonly noted in sampling logs, descriptions, and drilling evaluations.

In other disciplines, kärnytor may refer to the surface surrounding a nucleus or central region of a material or system. For example, in materials science or biology contexts the term can be used to describe the boundary of a core region or the outer envelope of a central component. In mathematical modeling or computer science, it can be used metaphorically to denote an interface between the core region and its surroundings.

Because the term is descriptive rather than canonical, authors may prefer more specific terminology in field-specific texts. For general readers, kärnytor conveys the idea of a boundary surface that defines and separates a core from its exterior.
