By What is agglomerate in geology?
Agglomerate, large, coarse, rock fragments associated with lava flow that are ejected during explosive volcanic eruptions. Although they closely resemble sedimentary conglomerates, agglomerates are pyroclastic igneous rocks that consist almost wholly of angular or rounded lava fragments of varying size and shape.
What is agglomerate?
: gathered into a ball, mass, or cluster specifically : clustered or growing together but not coherent an agglomerate flower head. agglomerate. noun.
How is agglomerate formed?
They typically form proximally during Strombolian eruptions, and are common at strongly peralkaline volcanoes. Some large agglomerate deposits are deposited from pyroclastic density currents during explosive caldera-forming eruptions, such as at Santorini, Taal, and Campi Flegrei.
What is agglomerate used for?
It forms from pyroclastic eruptions and generally fills in the vents of volcanoes during explosive activity or during caldera collapse. Often the origin of such deposits are uncertain and the term agglomerate has been used to define deposits which are actually vent breccias or debris flows like lahars.
What is the difference between conglomerate and agglomerate?

Why do companies agglomerate?
Agglomeration of firms in particular regions is driven by several factors that can be explained by localization—the clustering of similar firms because of geographic advantages, such as access to inputs—and urbanization—the clustering of firms in different industries due to the advantages the cities themselves provide.
What is agglomeration also called?
Agglomeration is also commonly referred to as particle size enlargement. While powder agglomeration results in particles that look visibly different, chemically speaking, the solid particles are the same as before they were agglomerated.
Why does agglomeration happen?
During the initial contact of water and cement particles, agglomerations tend to happen due to relatively large van der Waals forces of attraction. The range of this attraction is between 5 and 7 nm [14], entrapping water between particles.
What is agglomeration process?
In powder processing, agglomeration is defined as the process of amassing material fines into cohesive units like pellets or granules. Simply put, powder agglomeration means making fine powdery particles stick together to form larger particles that are easier to handle.
What is meant by agglomeration economy?
: a localized economy in which a large number of companies, services, and industries exist in close proximity to one another and benefit from the cost reductions and gains in efficiency that result from this proximity The existence of agglomeration economies can imply different things for local and national …
What is an example of an aggregate?
An aggregate is a collection of people who happen to be at the same place at the same time but who have no other connection to one another. Example: The people gathered in a restaurant on a particular evening are an example of an aggregate, not a group.
