Floor (geology)
A hive in the sense of geology is a larger, irregularly shaped, relatively homogeneous rock mass which, with steep contacts, penetrates other rocks as foreign bodies or is embedded in them. The term is closely related to the geomorphological term mountain stock , because such a rock mass is often carved out by weathering , and then forms a more or less steep mountain, or, if it is particularly large, an entire mountain massif .
Types
Depending on the material and origin, a distinction is made between different types of sticks:
- Eruptive stock - plutonic (batholith) or sub-volcanic (duct) formed, e.g. B. made of granite or dolerite
-
Sediment stock - (primarily) formed by
sediment
- Salt dome - secondary to salt deposits
-
Kalkstock - mountain massifs of limestone mountains , also consisting of dolomite (then called dolomite stock ). The term is often used exclusively because of the appearance for steep limestone mountains and has no primarily sedimentary causes, in contrast to
- Reefstock - fossil reef bodies which, due to their special sedimentological and petrographic properties, are carved out of the surrounding rock as relatively steep elevations; The term coral stock is also used on the limestone bodies, which drop steeply below the sea surface, of recently still active coral reefs, e.g. B. in the South Seas , applied
