Microwave-assisted mechanical excavation has been considered as a promising rock breakage method and is widely studied in recent years. Heating characteristics of minerals are the basis of research on the weakening effect of microwave irradiation on rock. In this paper, 14 igneous rock-forming ...
Igneous rock is one of the three major classifications: igneous, sedimentary, and metamorphic. It is the one type that forms directly from cooling magma either under or on the surface. If cooling below the surface, it is magma cooling. If cooling above the surface, it is lava cooling....

Intrusive and extrusive igneous rocks are the two types of igneous rocks. The difference between the two depends on how the rocks form: intrusive rocks cool underground, where extrusive rocks cool when lava oozes out on the surface of the earth. How do you tell if a rock is intrusive or ...
A rock undergoing metamorphism remains a solid rock during the process. Rocks do not melt during most conditions of metamorphism. At the highest grade of metamorphism, rocks begin to partially melt, at which point the boundary of metamorphic conditions is surpassed and the igneous part of the roc...
Figure 1. The White House of the USA is made of a sedimentary rock called sandstone. The White House (shown in figure 1) is the official home and workplace of the President of the United States of America. Why do you think the White House is white? If you answered, “Because it is...

Analysis of rock spectrum is a fundamental work for rocks and minerals detection by using remote sensing. Our work is focused on characteristics of composite igneous rocks within 8~14 um, and studying the relationship between emissivity of rocks and their mineral ingredient, structure, alteration, ...
According to the newspaper record, Ashikule volcano clusters in Xinjiang erupted in 1951. It is the latest eruption in Chinese Mainland. The products of volcano, eruption types and eruption scale in this area are still not well understood because it is h
How many types of sedimentary rocks are there? How does a sedimentary rock become an igneous rock? How are sedimentary rocks formed through physical processes? What are non-clastic sedimentary rocks? What type of sedimentary rocks form the breakdown of plants?
