Everything about Horst Geology totally explained
» This article refers to the geological form. For other uses, see Horst.
In physical
geography and
geology, a
horst is the raised fault block bounded by normal
faults formed from extension of the Earth's crust. The raised block is a portion of the
crust that generally remains stationary or is uplifted while the land has dropped on either side.
The
Vosges and
Black Forest are examples of horsts, the Table, Jura and the Dôle mountains are results of the latter. The word is also applied to those larger areas, such as the
Russian plain,
Arabia,
India and Central
South Africa, where the
continent remains stable, with horizontal table-land
stratification, in distinction to folded regions such as the
Eurasian chains.
"Horst" is the
German word for '
eyrie', the nest of a raptor (such as an
eagle) that's located on a high place such as a cliff.
Horsts and hydrocarbon exploration
In many
rift basins around the world, the vast majority of discovered
hydrocarbons are found in conventional traps associated with horsts. For example, much of the petroleum found in the
Sirte Basin in Libya (of the order of tens of billions of barrels of reserves) are found on large horst blocks such as the
Zelten Platform and the
Dahra Platform and on smaller horsts such as the
Gialo High and the
Bu-Attifel Ridge.
