Igneous Rock Diagram

All magma develops underground in the lower crust or upper mantle because of the intense heat there.

Igneous rock diagram. These are the mineral groups used for classification in qapf diagram. A qapf diagram is a double ternary diagram which is used to classify igneous rocks based on mineralogic composition. The term igneous rock cycle is not really a term at all but in terms of the rock cycle igneous rocks are the beginning place.

Igneous rocks form when magma molten rock cools and crystallizes either at volcanoes on the surface of the earth or while the melted rock is still inside the crust. Q a p and f percentages are normalized recalculated so that their sum is 100. Clicking on the minature thumbprints will allow the diagrams to be shown at a larger size.

The diagram in figure 3 4 1 can be used to help classify igneous rocks by their mineral composition. An important feature to note on this diagram is the red line separating the non ferromagnesian silicates in the lower left k feldspar quartz and plagioclase feldspar from the ferromagnesian silicates in the upper right biotite amphibole. In plutonic rocks all of the minerals are crystallized into visible grains.

This is the origin of igneous rocks. Drag the rock name to the correct rock. 5 igneous rock identification match the name to the rock.

Igneous rocks can have many different compositions depending on the magma they cool from. Enough examples are shown for any new data to be typed. The acronym qapf stands for quartz alkali feldspar plagioclase feldspathoid foid.

Formation of ignerous rocks diagram representing the formation of igneous rocks. Jan 22 2017 these diagrams show igneous rock diagrams that the iugs uses to classify phaneritic and aphanitic igneous rocks. Learn vocabulary terms and more with flashcards games and other study tools.
