Transcript of Volcanism in Pakistan

Volcanism in Pakistan
The term mud volcano or mud dome are used to refer to formations created by geo-excreted liquids and gases, although there are several different processes which may cause such activity. Hot water mixes with mud and surface deposits. Mud volcanoes are associated with subduction zones and about 700 have been identified. Temperatures are much lower in these processes than found at igneous volcanoes.
About 86% of the gas released from these structures is methane, with much less carbon dioxide and nitrogen emitted. Ejected materials are often a slurry of fine solids suspended in liquids which may include water, which is frequently acidic or salty, and hydrocarbon fluids.
List of volcanoes in Pakistan
This is a list of active and extinct volcanoes in Pakistan. Most of these are mud volcanoes, rather than the conventional magmatic type.

Fissure vent

A fissure vent, also known as a volcanic fissure or simply fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity. The vent is usually a few meters wide and may be many kilometers long. Fissure vents can cause large flood basalts and lava channels. This type of volcano is usually hard to recognize from the ground and from outer space because it has no central caldera and the surface is mostly flat.
Types of volcanoes in Pakistan
There are two types of volcanoes in Pakistan , first the mud volcano and second the fissure vent volcano!

Lets study about them!
