I'm modeling an ontology for the field of geology.

Trying to represent the ontology in first order logic, considering the necessary and sufficient conditions for each concept, I have found some challenges regarding to a specific concept, called Sedimentary Facies.

The current domain definition of Sedimentary facies is as follows:

A Sedimentary facies is a amount of rock in a body of rock, visually distinguishable (through discontinuities of visual properties) of adjacent amounts of rock in the same body of rock.

How can I formalize this concept in FOL?

Apparently, the instances of this concept are determined depending on each other, in a relative way. I'm not sure that I canlogically determine what are the instances of the concept.

Best regards.
