How is the vesicular texture of an igneous rock formed? Answer by SBDW1 _. Confidence votes 23.9K. A vesicular texture is one where there are small voids within the igneous rock. These tend to form in extrusive igneous rocks due to the loss of confining pressure which causes gasses dissolved in the molten material to come out of solution or exsolve.

How Do Flood Basalts Form? Quick Answer. Flood basalts are continuous eruptions of magma through long fissures in the Earth's crust. The huge volume of magma required for these eruptions is thought to come from a destabilized layer of the core and mantle boundary.

What is basalt? Rockhound. Basalt is an igneous rock that forms from the relatively rapid solidification of basaltic lavas; that is, those magmas that are relatively high in iron and magnesium, and low in silica and aluminum.These features give basalt its dark color and higher relative density when compared to silicate igneous rocks.ockhound. Basalt is an igneous rock that forms from the relatively rapid solidification of basaltic lavas; that is, those magmas that are relatively high in iron and magnesium, and low in silica and aluminum.

- Basalt a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances. It is also found as intrusive dikes and sills.

Talk:Basalt Basalt which erupts under open air (that is, subaerially) forms three distinct types of lava or volcanic deposits: scoria; ash or cinder (breccia); and lava flows. Basalt in the tops of subaerial lava flows and cinder cones will often be highly vesiculated, imparting a lightweight frothy texture to the rock.asalt which erupts under open air (that is, subaerially) forms three distinct types of lava or volcanic deposits: scoria; ash or cinder (breccia); and lava flows.

Columbia River Basalt Group The Columbia River Basalt Group is thought to be a potential link to the Chilcotin Group in south-central British Columbia, Canada. The Latah Formation sediments of Washington and Idaho are interbedded with a number of the Columbia River Basalt Group flows, and outcrop across the region.

Volcanic rock Volcanic rocks often have a vesicular texture caused by voids left by volatiles trapped in the molten lava. Pumice is a highly vesicular rock produced in explosive volcanic eruptions.

Why can't people with tracheostomy talk? A trach routes air from the lungs up through the trach tube and back again. This air usually goes up through the vocal cords (making sound when you talk) and out your mouth. The trach will bypass the cords. With out the air going up through the vocal cords, sound can't be made. See the link below, it is a diagram (side view) of a trach. Note the vocal cords and where they are in relation to the trach. http://www.goshprivate.nhs.uk/factsheets...

- It sounds like in your case the agates are formed in the bubble holes in the basalt flows. This can be called amygdaloidal basalt. When the basalt weathers the agates do not decompose as fast as the host rock does and the agates end up in the stream and river drainage.

What Is Basalt Made Of? Basalt is typically made up of augite or feldspar with some silica and olivine. A type of igneous rock, basalt can be found on oceanic floors and terrestrial landscapes formed by lava flows.

- Rhyolite Porphyry Some of the best-known examples of rhyolite can be found in the Yellowstone Park region and in the southwestern United States. Many of the rocks in those areas formed approximately 600,000 years ago through a series of massive volcanic eruptions. Rhyolite is a fine-grained extrusive igneous rock that is mineralogically similar to granite. It chiefly contains orthoclase feldspar and quartz, but may contain lesser amounts of plagioclase feldspar, pyroxenes, biotite, and amphiboles.

Pumice Density of specimen approximately 0.25 g/cm 3; scale in centimeters. Pumice /ˈpʌmɨs/ , called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals.It is typically light colored.Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls and being dark colored and denser. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano.The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization.t is typically light colored.

Pumice The pore spaces (known as vesicles) in pumice are a clue to how it forms. The vesicles are actually gas bubbles that were trapped in the rock during the rapid cooling of a gas-rich frothy magma. The material cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure. Thus, pumice is an amorphous volcanic glass known as a  mineraloid .

Holy Pilgrimage â Goa Sate â ( Mahadev temple, Mahasala temple, Mahamaya Kalika temple, Mandodari temple, Mangueshi temple, Nagueshi, Shanta Durga temple, Ramnathi and Ravalnath) -1 By definition, basalt is an aphanitic igneous rock with less than 20% quartz and less than 10% feldspathoid by volume, and where at least 65% of the feldspar is in the form of plagioclase.Basalt features a glassy matrix interspersed with minerals.asalt is used in construction (e.g. as building blocks or in the groundwork), making cobblestones (from columnar basalt) and in making statues. Heating and extruding basalt yields stone wool, said to be an excellent thermal insulator.

- The texture is the main difference between Basalt and Scoria. Basalt is aphanitic, which means it is made of very fine grains. Scoria is vesicular, which means there are bubbl … es in the surface that occurred as the basaltic lava cooled.

- The protolith may be sedimentary rock,igneous rock or another older metamorphic rock. Texture-Foliated Foliation refers to flat or wavy planar features (looking likelayers) caused by the alignment of platy minerals such as mica.Foliation may also look like alternating bands of light and darkminerals.

Basalt Most of the basalt found on Earth was produced in just three rock-forming environments: 1) oceanic divergent boundaries, 2) oceanic hotspots, and 3) mantle plumes and hotspots beneath continents. The images on this page feature some of these basalt-forming environments.
