The mud volcanoes along the Makran Coast and offshore are formed by the accumulation of diagenetic fluids (mud, water, gas, oil?) escaping from unconsolidated sand and shaly sediments undergoing compaction and tectonic pressures. The mud volcanoes are pretty common around the world, Other examples are those in the Baku region of the Caspian domain and the ones in the Gulf of Mexico. Is their any other examples of mud volcanoes and can we have input of mantle material in these mud volcanoes. If yes? then what type of minerals we can have from those mud volcanoes.
There are different types of mud volcanoes. The most common are:
1) accumulation of mud and rock ejected by volcanic gases world-famous examples are:
=> Solfatara Pozzuoli, Italy; and Rotoroa, New Zealand)
2) accumulation formed by escaping petroliferous gases world-famous example is => Baku, Azerbeijan
The mineralogical and chemical composition of mud volcanoes strongly depends on the surrounding and penetrated soils and geological formations.
As basalt often contains olivine and pyroxene, this inevitably proves the presence and involvement of upper mantle material.

Thank you very much Respected Guenter Grundmann, ur answer regarding the upper mantle involement of minerls i e olivine and pyroxene in basalt. its a good i formation.
Thanks Regads

The "mud volcanoes" are the surface manifestation of mud diapirism, related with the materials confined in depth (diapirs), that reaching the surface through fractures, associated both with strike slip and normal faulting. This process, generate the verticalization of the sedimentary sequences and facilitating the mud movement, through the same fractures and equally between friable and porous sandy layers or strata.
The western of the Colombian Caribbean coast, the same as other parts on earth associated with Cenozoic accretionary prisms, are influenced by the activity of the mud diapirism. This phenomenon, is originated by both the density contrast between overpressuring in depth muddy mass material (of plastic characteristic) with gases under conditions of high pressure and the denser surrounding overburden, and by tectonic compression. .
