Horst (geology) - Wikipedia
In physical geography and geology, a horst is a raised fault block bounded by normal faults. [1] Horsts are typically found together with grabens. While a horst is lifted or remains stationary, the grabens on either side subside. [2] This is often caused by …
Horst and graben - Wikipedia
In geology, horst and graben (or range and valley) refers to topography consisting of alternating raised and lowered fault blocks known as horsts and grabens. The features are created by normal faulting and rifting caused by crustal extension. [1]
Horst and graben | Faulting, Tectonics & Geomorphology
Horst and graben, elongate fault blocks of the Earth’s crust that have been raised and lowered, respectively, relative to their surrounding areas as a direct effect of faulting. Horsts and grabens may range in size from blocks a few centimetres wide to …
Horst and Graben - U.S. National Park Service
2020年4月22日 · Horst and Graben (valley and range) refers to a type of topography created when the earth's crust is pulled apart. This process, called extension, can stretch the crust up to 100% of its original size. As the crust is strained in this way, normal faults develop and blocks of the crust drop down to form grabens, or valleys.
Horst and Graben | U.S. Geological Survey - USGS.gov
2014年12月31日 · A horst is an upthrown block lying between two steep-angled fault blocks. A graben is a down-dropped block of the earth's crust resulting from extension, or pulling, of the crust.
Horst - SpringerLink
A horst is a fault block, generally elongate, that has been raised relative to the blocks on either side without major tilting or folding. The bordering faults, or fault zones, are usually of near-parallel strike and are steeply dipping, along which the vertical displacement has …
Horst and Graben - Geomorphology, Formation and Examples
A horst is a raised block of the Earth's crust that has lifted or stayed stationary while the land around it (graben) has sunk. Horst and Graben are found together in an extensional environment. The graben is the block that has been downthrown, while the horst is the block that has been upthrown next to the graben.
Horst Structures: Definition & Geology | Vaia
Horst structures are elevated blocks of the Earth's crust, formed between two parallel fault lines, rising above the surrounding terrain (grabens). Characteristics include parallel fault lines, uplifted central block, and patterns of ridges and valleys.

2023年9月28日 · In geology, horst and graben (or range and valley) refers to topography consisting of alternating raised and lowered fault blocks known as horsts and grabens. The features are created by normal faulting and rifting caused by crustal extension.
1.12: Tectonic Environments of Faulting - Geosciences LibreTexts
A horst is a block between two normal faults that dip away from each other, in opposite directions. The rocks in a horst stand higher than the rocks on either side. A graben is a block between two normal faults that dip towards each other. The rocks in …
