What is the melting point of basalt?

specific heat of basalt is 0,2


Which rock can stand the highest temperature before melting?

Igneous rocks like granite and basalt have high melting points and can withstand high temperatures before melting. Granite typically melts at around 1200-1300°C, while basalt melts at about 1000-1200°C.


Which two processes commonly generate magma?

decompression melting and wet melting (the addition of volatiles) :)


Basalt is generated by?

Basalt is generated by the solidification of lava that erupts from volcanoes. It is a common igneous rock that forms from the cooling and crystallization of molten rock material.


What observation has been about the age of the basalt that forms a mid ocean ridge?

New magma of basalt composition emerges at and near the axis because of decompression melting in the underlying Earth's mantle.


Why are basalt and granite the most common rocks of the crust?

Because they are the product of eutectic melting and density separation of the melts.


Can you melt basalt hot massage stones?

Basalt hot massage stones are typically heated to a specific temperature range and used for massage therapy. Melting basalt stones at high temperatures could damage them and may release harmful gases. It is not recommended to attempt to melt basalt hot massage stones.


How can quartz be used in your everyday lives?

Basalt is a fine-grained grey to black extrusive volcanic rock that forms after the rapid cooling of lava at the surface of a planet. On the earth, most basalt magmas have formed by melting decompression of the mantle. Basalt can be used in building blocks for construction, making cobblestones from columnar basalt and making of statutes.


What type of rocks form from melting and cooling?

These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.


What special property do the minerals within basalt have?

Many basalt minerals have a high melting point, making them resistant to high temperatures. This property makes basalt a good choice for applications where heat resistance is required, such as in the construction of buildings or roads.


Why does alkalic basalt contain less silica than tholeiites?

The magma that forms alkalic basalt forms under conditions with a higher fraction of partial melting that the magma that forms tholeiitic basalt. This means that the resulting alkalic melt contains a higher percentage of the minerals with a low silica content.
