horst

This term is a specialized geological descriptor used primarily in structural geology and tectonics. It describes a specific topographic feature where a block of crust is pushed upward or remains elevated while the surrounding land sinks. It is almost always used in direct contrast with its counterpart, the graben.

Because it is a technical term of art, it is rarely encountered in general conversation and is confined to academic papers, geological surveys, and textbooks. It carries a neutral, descriptive tone and lacks any metaphorical or colloquial application in standard English.
