Basalt And Granite Density

The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.
Basalt and granite density. The tholeiitic and the alkali basalts. Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. 6 11 density of granite and basalt lesson concept density of basalt and granite affect the formation of landmasses on earth.
Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. It is mostly made out of quartz mica and feldspar. Since gabbro and basalt are made of the same minerals their densities are similar. Time 120 minutes lesson can be divided into two sessions maintaining the order of the lesson materials per group groups of 4 5.
Granite is an igneous plutonic rock which is. Link mountain formation in lesson 6 10 is dependent upon the density of the crust. It is common both on earth and other planetary bodies. It wants to be there and heat is the key which unlocks the door.
The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. Rock density is very sensitive to the minerals that compose a particular rock type. And if you know your igneous petrology you will see that the more mafic rich in magnesium and iron a rock is the greater its density. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.
It forms from lava flows which extrude onto the surface and cool. Basalt is an aphanitic fine grained igneous rock that is relatively low in silica and alkali metals it has less than 10 feldspathoid by volume with at least 65 of the rock consisting of feldspar in the form of plagioclase this places basalt in the basalt andesite field of the qapf diagram basalt is further distinguished from andesite by its silica content of less than 52. Basalt extrusive igneous volcanic rock that is low in silica content dark in color and comparatively rich in iron and magnesium. Granite is a felsic rock meaning that it has a high silicon content.
Basaltic crust is dark and thin and heavy while granite is light and accumulates. As it turns out most of the ocean floor is basalt and most of the continents are granite. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Gabbro s density ranges from 2 7 3 3 g cm 3.
Basalts may be broadly classified on a chemical and petrographic basis into two main groups. Learn more about basalt in this article.
