Using the igneous rock classification chart, note the textural terms located along the y-axis and compositional terms located along the x-axis. To properly use the igneous chart, you will simply perform a cross reference of texture and composition. The rock name is determined by the intersection...

intrusive igneous rock explanation: granite is formed below the earth’s surface resulting in large crystals when cooling takes place. hence it is classified as intrusive igneous rock. 5. cooling and solidification of magma or lava lead to the formation of ___ rock. metamorphic igneous sedimentary...
Petrographers apply the term loosely and directly to members of the families given in Table 1 , often on purely petrographic grounds without knowledge of the SiO 2 content from analysis. Other general terms in igneous rock classification cut across and are complementary to the acid–intermediate–...
Finally, a strength classification chart and a brittleness classification table are presented, providing reliable and low-cost methods for the classification of igneous rocks. 展开 关键词: Rock mechanics Strength Brittleness Hardness Igneous rocks Classification ...

Distinguishing different kinds of igneous rocks is difficult because of their subtle differences. Synthetic aperture radar (SAR) is sensitive to rock surface morphology, which can help a lot in classification. Dual-pol SAR data have the advantages of low
