Igneous rocks are classified based upon their what?
Igneous rocks can be classified by their method of formation and by their mineralogy.
Igneous rocks are classified based upon their composition and what?
texture
Classifications of minerals?
A rock's mineral composition is a determining factor in rock identification.
Igneous rock are classified based upon their?
There are two types of igneous rocks; intrusive and extrusive. Intrusive igneous rocks are formed underneath the earth's surface from magma where it cools slower and develops large crystal structures. Extrusive igneous rocks are formed above the earth's surface from lava that cools quickly and creates rocks with smaller, finer crystal structures.
How are geodes classified?
The igneous geodes are classified as intrusive and the sedimentary geodes are classified as chemical based on properties.

How igneous rock classified?
Geologists classify rocks by where they are formed; above ground or under ground
What causes the different colours in rocks?
The different colours are from different minerals. A reddish colour could be due to a mineral containing a lot of iron, for example. Weathering, staining, mineralogy and method of formation all play a part.
Rocks are classified as igneous sedimentary or metamorphic based primarily on their?
Based on their method of formation.
Rocks are classifed as?
mineral Sedimentary, igneous, or metamorphic, based on their method of formation.
What is the igneous rock between granite and basalt?
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
Was igneous rocks were classified by their their origin texture and shape?
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
