Dating a metamorphic rock can indicate the time since metamorphism occurred.
A metamorphic rock is formed by the elements, minor heat, and compression. When the metamorphic rock is melted by magma, this would indicate that the metamorphic rock is under the surface of the earth. If it rises and cools again you will have an extrusive igneous rock. In a lot of cases, this is metamorphic rock on the surface under the influence of lava. This would change the composition and it would not longer be metamorphic, but rather igneous.
If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.Google radiometric dating.
A metamorphic rock.
in a metamorphic rock you find rock.
Chert is NOT a metamorphic rock.
No.
Metamorphic rock displaying banding is referred to as foliated metamorphic rock.
Rock can be changed into metamorphic rock by heat and pressure.
These rock is Metamorphic. metamorphic rocks are found in Africa.
Radioactive dating is only useful in dating igneous and metamorphic rock. Organic material that has not fossilized and does not exceed 70,000 years of age can be dated by Carbon dating techniques. Sedimentary rock can only be dated by its association with igneous and metamorphic rock.
metamorphic rock
All rock types, igneous, sedimentary, and even metamorphic can be altered to new metamorphic rock.
