WitrynaIgneous rocks can be divided into four categories based on their chemical composition: felsic, intermediate, mafic, and ultramafic. The diagram of Bowen’s reaction series ( Figure 7.6) shows that differences in chemical composition correspond to differences in the types of minerals within an igneous rock. Igneous rocks are given names based ... WitrynaPhenotrachytic welded tuff. Tuff is relatively soft and porous rock that made of ash and other sediments from volcanic vents that has solidified into the rock. After following ejection and deposition, the ash is compacted into a solid rock in a process called consolidation. Rock that contains greater that 50% percent tuff is considered tuffaceous. eee wood カタログ
