What is another word for block lava?
Pronunciation: [blˈɒk lˈɑːvə] (IPA) 
Block lava is a type of lava that has viscid to stiff consistency and forms massive, rough-surfaced blocks upon solidification. The term "block lava" is commonly used in geology to describe this particular type of lava. However, there are several synonyms that can be used to refer to block lava, including felsic lava, andesitic lava, viscous lava, and rock-like lava. Felsic lava and andesitic lava typically refer to lava types that have higher silica content than basic lava types. Viscous lava, on the other hand, refer to lava that has high viscosity due to its chemical composition. Rock-like lava, as the name suggests, describes the solid-state appearance of block lava formations.
