层控矿床_百度百科
层控矿床（stratabound ore deposit） 产于一定的地层中，并受一定地层层位限制的。 层控矿床的概念最初由德国A.毛赫尔(1939)提出，是指矿床与地层之间的几何形态特征或产状关系，而没有特定的成因概念。
Stratabound Deposit - an overview | ScienceDirect Topics
A stratabound deposit is defined as a type of mineral deposit where ore minerals are exclusively confined within a single specific stratigraphic unit, which may include various orientations of mineralization such as layers, veins, stringers, and alteration zones.
What is the difference between stratiform and stratabound?
2021年4月25日 · What does stratabound mean? Said of a mineral deposit confined to a single stratigraphic unit. The term can refer to a stratiform deposit, to variously oriented orebodies contained within the unit, or to a deposit containing veinlets and alteration zones that may or may not be strictly conformable with bedding.
Origin and evolution of a porphyry-skarn-stratabound system ...
2024年8月1日 · We investigated the Dongguashan deposit, one of the largest and most representative stratabound Cu (– Au) deposits in eastern China. Three mineralization types were recognized based on field and petrologic studies: porphyry, skarn, and stratabound.
Notes on the terms ‘stratiform’, ‘stratabound’ and ‘stratigraphic ...
2007年8月3日 · The terms stratiform orebody and stratabound orebody are defined and it is suggested that stratiform orebodies are a particular form of stratabound orebodies. The former may be subdivided into sedimentary, volcanic, hypabyssal, vein, replacement and …
Sediment-hosted copper deposits are stratabound, that is, they are restricted to a narrow range of layers within a sedimentary sequence but do not necessarily follow sedimentary bedding. They are epigenetic and diagenetic, that is, they are formed after the host sediment is deposited, but in most cases, prior to lithification of the host.

2017年8月24日 · Stratiform and stratabound are also essential terms in mineral deposits formed by sedimentary processes. Thus, a stratiform deposit means a mineral deposit related to a concrete stratigraphic bedding, while a stratabound deposit is limited to a determined part of the stratigraphic column.
Stratabound ore deposit is "said of a mineral deposit confined to a single stratigraphic unit" (Glossary of Geology, A. G. I. 1980). To elucidate the limits of this definition is, of course, problematic, and is not possible without clarifying the scale used in describing the "single stratigraphic unit" considered (see also
Stratabound Ore Deposits in the Andes: A Review and a
Systematic investigations of stratabound ore deposits in the Andes are relatively modern. Perhaps as a result of the very intensive Andean magmatic activity, it was not easy to break with the concept that most ore deposits are veins and replacement bodies related to...
Most large gold deposits in iron-formation (GDIF) are strata-bound, bed-controlled concentrations of sulfide minerals and gold that were probably formed by syngenetic, hot-spring processes during deposition of iron-formation.
