I used to go to the movies.
What are the test instruments used in electronics?
Some test instruments used in electronics are:Multimeter - Used to measure voltage, ampere and resistanceOscilloscope - Used to measure frequency and oscillations
What does greenschist look like?
Greenish, foliated, with a soft sheen.
A metamorphic rock formed from basalt?
Greenschist. It is schist
What can metamorphic rocks change into?
Greenschist, blueschist, zeolite, granulite and eclogite high grade metamorphic rocks.
Is vesuvianite a igneous sedimentary or metamorphic rock?
It can be sedimentary when mixed with dolomite or metamorphic when mixed with greenschist A.T. Mineralogist
What is the meaning of Protolith in geology?
"protolith" refers to the original composition of an altered rock. for example, a basalt was the protolith to a rock thats presently a greenschist.
At temperature 600 degree centigrade and 14 kb basalt metamorphism produces?
At a temperature of 600 degrees Celsius and 14 kilobars pressure, basalt metamorphism typically produces minerals such as amphibole, pyroxene, and plagioclase feldspar, resulting in the formation of greenschist or amphibolite facies metamorphic rocks. These minerals form in response to the high temperature and pressure conditions, leading to changes in the original basaltic rock composition.
What is the difference between facies in sedimentary rocks and facies in metamorphic rocks?
Most regional metamorphic rocks are formed in conditions within this range of geothermal gradients, passing through the greenschist facies to the amphibolites
What is the protolith for greenstone?
The protolith for greenstone is usually basaltic or andesitic volcanic rock that has undergone metamorphism, resulting in the formation of chlorite, epidote, and actinolite minerals that give greenstone its characteristic green color. These rocks are typically found in greenschist facies metamorphic environments.
What type of metamorphism did shale go through to become slate?
To metamorphose shale into slate you require a regional metamorphic environment which reaches temperatures of between 400-600oC and pressures of between 3-4 Kilo-bars (a burial depth of about 18 Km). The name of this sort of metamorphism is 'greenschist facies' with a 'Barovian' mechanism.
Basalt can change into what metamorphic rock?
When basalt undergoes metamorphism, it can change into a metamorphic rock called greenstone. Greenstone is a fine-grained metamorphic rock that forms from the alteration of basalt through metamorphic processes like recrystallization and the growth of new minerals.
What happens to a basalt when you add heat and pressure?
When heat and pressure are applied to basalt, it can transform into a metamorphic rock called greenstone or greenschist. This process can cause minerals in the basalt to recrystallize, resulting in a more compact and foliated texture. Overall, basalt tends to become denser and more resistant to weathering under these conditions.
How is greenstone formed?
Greenstone, also known as greenschist, is a non layered metamorphic rock derived from basalt, gabbro or similar rocks containing sodium-rich plagioclase feldspar, chlorite, epidote and quartz. Chlorite and epidote give the green color. New Zealand Jade or Greenstone ( Pounamu in Maori ) comes in four main types: Kawakawa, Kahurangi and Inanga are Nephrite or Calcium Magnesium Silicate. Tangiwai is Bowenite or Iron Magnesium Silicate.
