What does shale and basalt turn into?

What does shale and basalt turn into?

Shale (sedimentary) could have become slate. Slate (metamorphic) if put under more pressure could change into a schist. A basalt (igneous) could also become a schist. Limestone (sedimentary) can become marble.

What metamorphic rock is produced from basalt?

Basalt, the dark-colored volcanic rock, produces two main types of metamorphic rocks: (1) amphibolite and (2) green schist, as illustrated in Figure 1.1. On a regional scale, the distribution pattern of igneous and metamorphic rocks is belt-like and often parallel to the borders of the continents.

Which type of rock is formed when heated?

Metamorphic rocks
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word “metamorphic” comes from Greek and means “To Change Form”.

Is basalt a sedimentary metamorphic or igneous?

What is Basalt? Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro.

Is Basalt metamorphic rock?

Intense heat or great pressure transforms basalt into its metamorphic rock equivalents.

Is Basalt a sedimentary metamorphic or igneous?

How do metamorphic rocks form?

Metamorphic rocks form from pre-existing rocks (“parent rocks”) due to changes in either temperature, pressure, or volatiles within the earth, often by a combination of all three.

How do metamorphic rocks recrystallize under tectonic pressure?

Regional metamorphic rocks recrystallize under tectonic pressure, directed pressure – the rocks are squeezed more in some directions than others. Directed pressure during metamorphism causes flat or elongate minerals to grow at right angles to the direction of maximum compression.

How do you define the extent of metamorphism?

1. Figures 8.12 & 8.13: The extent of metamorphism can be defined on the basis of metamorphic grade and Metamorphic Facies. The term ‘Metamorphic Facies’ describes the grouping of rocks of various mineral compositions formed under different temperature and pressure conditions.

What are the classification of foliated metamorphic rocks?

Glossary Metamorphic Rock Classification Table Foliated Metamorphic Rocks Crystal Size Mineralogy Parent Rock Metamorphism Rock Name very fine clay minerals shale low grade regional slate fine clay minerals, biotite, muscovite shale low grade regional phyllite medium to coarse serpentine, magnetite, talc, chlorite peridotite, dunite
