Basalt Rock Formation Properties Composition Uses

Basalt is an extrusive igneous rock that forms from the rapid cooling of volcanic lava.

. Basalt like most dark magmas has a low amount of silica. Outer part of forming pillow cools very quickly in contact with cold seawater while the interior still fills with molten lava. Aa basalt forms when lava has high viscosity flows poorly like honey or flow is turbulent.

Basalt is the dark heavy volcanic rock that makes up most of the worlds oceanic crust. The intrusion of a narrow sill or igneous dike below the crust. C a mafic magma cooling on Earths surface.

Under room temperature basalt stone breaks before gaining plastic properties. The fault must be older. A mafic magma cooling in the subsurface.

Igneous rocks can be extrusive or intrusive base on the formative environment. Has small crystals is an intrusive igneous rock forms from heat and pressure forms from contact. ˈ b æ s ɔː l t-əl t.

Lava skin becomes ductile as it cools and slumps together forming rope like texture. A a mafic magma cooling in the subsurface. As basalt forms at the mid-ocean ridge which of the following is correct.

Learn vocabulary terms and more with flashcards games and other study tools. Identify the composition and chemistry of basalt how it is formed and used and the. Some of it erupts on land too but to a first approximation basalt is an oceanic rock.

This is in large part due to the amount. It may be porphyritic containing larger crystals in a. It is usually fine-grained due to rapid cooling of lava on the Earths surface.

Generally igneous rocks are formed from molten. Their relative ages cannot be determined based on the information given B. A basalt would form under conditions that included A.

On the other hand basalt flows block. Basalts occur in every tectonic environment so weneed to know a little more about them before we can successfully use them asindicators of tectonic and magmatic processes. Basalt is an example of extrusive igneous rocks.

Start studying Rock cycle task cards. A basalt would form under conditions that included. The basalt cools contracts and becomes more dense.

If a basalt body cuts across a fault what are the relative ages of the basalt and the fault. Tectonic Environments and eruptions Which of the following statements about basalt is NOT true. A felsic magma cooling in the subsurface.

Basalt is considered a mafic silicate rock. Basalt is primarily formed by the extrusion of lava flows onto the surface of the earth during a volcanic eruption. Basalt is an igneous rock formed from the lava flows that cool off pretty quickly either on the surface or very close to the surface.

B ə ˈ s ɔː l t ˈ b eɪ s ɔː l t is an aphanitic fine-grained extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium. Basalt forms when magma cools very quickly. Basalt is a common gray to black volcanic rock.

Pahoehoe basalt forms when lava has low viscosity flows easily like water or flow is smooth. Recent basalts cover the underlying drainage pattern forming buried channels where the groundwater may be trapped under confining conditions. B a felsic magma cooling in the subsurface.

The basalt cools expands and becomes less dense. In contrast the basalt fibers exhibit flexible. Often basalt- low silica makes lava runny.

Among other characteristics mafic minerals and rocks are generally dark in color and high in specific gravity.
