I do not know specifically but it is fairly high in silica making it rather viscous and good for trapping/holding gas. Dactic magmas can be either exlposive volcanic events or just be mild lava flow depending on the amount of trapped gas.
Dactic sits between Rhyolitic and Andisitic in compostion. Rhyolitic is highest in viscosity have the most Silica then Dactic, andesitic then basaltic having the least silica.
there is a type and its lave
The lava composition of Mount Pelée in Martinique is typically andesitic, which means it contains minerals such as plagioclase, pyroxene, and amphibole. Andesitic lava is intermediate in composition between basaltic (low silica content) and rhyolitic (high silica content) lavas.
Andesitic lava is considered intermediate in composition. It has moderate silica content and viscosity, resulting in eruptions that produce both effusive and explosive activity.
The lava in the Andes is typically referred to as Andesitic lava, due to its composition being rich in silica and forming characteristic volcanic landforms in the Andean region.
Niether. Pahoehoe and a'a are both varieties of basaltic lava. The material from Pinatobo is of a dacitic composition, which is much more viscous than a'a or pahoehoe. It tends to erupt explosively, producing ash and pumice rather than lava flows. When dacitic lava does flow it creates a block lava flow.
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.
Lava domes are generally composed of felsic, highly viscous lava, usually dacite or rhyolite.

Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.

Volcanologists study lava. They examine the behavior, composition, and effects of volcanic activity, including the study of lava flows and eruptions.
Andesitic lava is considered intermediate in composition. It has moderate silica content and viscosity, resulting in eruptions that produce both effusive and explosive activity.
A geologist would examine the composition of lava, including its mineral content and chemical composition. They would also investigate the temperature and viscosity of the lava, as well as its eruption style and flow behavior. Additionally, they might study the texture and structure of lava rocks to understand how the lava cooled and solidified.
Composition, heat, and pressure.

Yes, when lava cools and solidifies, it forms igneous rock. The type of rock that forms depends on the chemical composition of the lava and the rate at which it cools.
