WebVolcanoes have also given us clues as well. Through melting experiments under various conditions, we’ve figured out what kind of mantle rock would produce magma of a given composition. Occasionally, the lava brings with it a solid chunk of mantle rock called a mantle xenolith. There are also geologic formations called ophiolites. WebPartial melting: Rocks contain a variety of different minerals. Magma flows out of the original rock long before the rock completely melts. Therefore, the magma that forms as a rock begins to melt does not have the same composition as the rock it came from. The magma tends to have more silica. This is the process that the melt carries away silica. bat 終了コード 255
