Tonalite and Basalt


Basalt and Tonalite


Definition

Definition
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture  
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth  

History
  
  

Origin
Tonale, Italy

Discoverer

Etymology
From Tonale Pass, northern Italy, + -ite1  
From Late Latin Basaltes (variant of basanites ), very hard stone, which was imported from Ancient Greek Basanites

Formation

Formation
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.  
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
