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 mineral composition and?
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
Rocks are classified as igneous sedimentary or metamorphic based primarily on their?
Based on their method of formation.
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.
Igneous rocks that result when lava solidifies are classified as what?
Extrusive igneous rocks.
Igneous rocks are classified based upon their what?
Igneous rocks can be classified by their method of formation and by their mineralogy.
How are igneous rocks classified acording to their..?
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.
what are igneous rock classified based upon?
Igneous rocks can be classified by their method of formation and by their mineralogy.
How are igneous metamorphic and sedimentary rocks classified?
They are classified by origin, method of formation, mineral composition, and texture.
How do you classify igneous rocks?
Look at them. There shape, size, color and feel! Dont worry you will figure it out....

Extrusive igneous rocks.
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.
How are igenous rocks classified according to composition?
Igneous rocks are classified using the IUGS classification system, which compares the total alkali (K2O + Na2O wt%) to the total Silica (SiO2 wt%) content.
