What is a Syngenetic in geology?
In economic geology, the term syngenetic has traditionally been used to refer to ore deposits formed at the same time as the enclosing rock as opposed to epigenetic that describes mineral deposits formed later.
What is meant by Syngenetic?
1 : of, relating to, or formed by syngenesis. 2 : formed at the same time as the enclosing rock —used of ore deposits — compare epigenetic.
What does epigenetic mean in geology?
In ore petrology, applied to mineral deposits of later origin than the enclosing rocks or to the formation of secondary minerals by alteration. Synonym of: epigenic.
What is Syngenetic and epigenetic?
2.1 Syngenetic and epigenetic genesis of ore deposits. Ore deposits of economic value are formed under varied geological conditions. In sedimentary rocks epigenetic processes, ore deposits are formed due to weathering and deposition of detrital sedimentary rocks in basins where placer deposits are emplaced.
What are the types of ore deposits?
Deposits are classified as primary, alluvial or placer deposits, or residual or laterite deposits. Often a deposit will contain a mixture of all three types of ore. Plate tectonics is the underlying mechanism for generating gold deposits.
What is hypogene process?
Hypogene is a term used only in the adjective form for any geological process genetically connected with deeper parts of the Earth’s crust or for mineral, rock and ore formed beneath the surface of the Earth. It is an opposite term to supergene. Such solutions and conditions of ore formation are also called hypogene.
What is Zooplastic?
— zooplastic, adj. the process of surgically grafting tissue from a lower animal onto the human body. — zooplastic, adj. See also: Animals. the process of surgically grafting tissue from a lower animal onto the human body.
What does synergetic mean?
working together
Synergetic means working together or cooperative. It can be used as another word for synergistic, which is used to describe things that produce, result from, or otherwise involve synergy. But when something extra happens, something greater, this is synergy.
What are 3 factors that affect epigenetics?
Several lifestyle factors have been identified that might modify epigenetic patterns, such as diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress, and working on night shifts.
What is an example of Epigenesis?
Jack eats a high fat and high sugar diet and is considered obese. These life choices could be blamed for Jack’s diabetes as they exemplify the principles of epigenesis. Jack didn’t have a genetic predisposition for diabetes, but developed it because of environmental influences.
How a ore is formed?
Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the newly-created igneous rock. Minerals found in such rock might include feldspar or mica.
What are types of ores?
There are mainly four kinds of ores like Ores Oxides; Ores Carbonate; Sulphide Ores; Ores Halides.
Which is an example of a syngenetic deposit?
Definition of syngenetic deposit. A deposit formed contemporaneously with the parent rock and enclosed by it. There are two types of syngenetic deposits, igneous and sedimentary. Some examples are nickeliferous sulfides, nontitaniferous magnetite, diamond, chromite, and corundum. Ref: Lewis.
Which is the best definition of a syngenetic element?
‘Setting quartz inclusions (at least the protogenetic and syngenetic ones) apart from your standard-issue nine-to-five mineral is the fact that they are stuck inside another growing mineral (quartz).’ ‘Paragenetic evidence indicates that the manganese oxides are pre-or syngenetic with respect to the barite.’
What’s the difference between diplogenetic and epigenetic rocks?
Much of the disagreement over “epigenetic” and “syngenetic” deposits is semantic; some ores and altered rocks are in part syngenetic and in part epigenetic and for them the term “diplogenetic” is proposed.
