4.5: Volcanism - Geosciences LibreTexts

Basaltic magma can form several rock types and unique landforms. Based on magma temperature, composition, and content of dissolved gases and water vapor, there are two main types of basaltic volcanic rocks with Hawaiian names – pahoehoe and aa. Pahoehoe is a basaltic magma that flows smoothly into a “ropey” appearance.

Management of Hard Rock Basaltic Aquifer through Aquifer

In the Maharashtra State of India, Deccan Trap basaltic lava flows are spread over around 82% of the area and form the most prominent aquifer in the entire state. Nasik district occurring in the northern part of Maharashtra also known as Khandesh represents a typical area of Deccan Trap basalt. The storage and transmission capabilities of the basaltic lava flow aquifer are very

Basaltic Gabbroic Rocks - Tulane University

2004.3.4  Although basaltic and gabbroic rocks are found in nearly all tectonic settings, they are the predominant igneous rock types of the ocean basins. Furthermore, basaltic and gabbroic rocks of the ocean basins represent magmas that have the least likelihood of being contaminated with continental crustal material, and thus should give us the best ...

A review on carbon dioxide sequestration potentiality in basaltic

2024.11.1  After the injection of 175 tons of CO 2, it was revealed that basaltic rock dissolution was the major driving factor for the mineral carbonation process, which took place within 400 days. Also, reaction path modeling revealed that a pH range of 5.2–6.5 of basaltic rocks having a low temperature of 20–50 °C was suitable for mineralization ...

Characteristics of terrestrial basaltic rock populations: Implications ...

2016.8.1  Basaltic rock sphericity appears to be controlled primarily by cooling fractures in the rock. The exponential shape of the size-frequency distributions of these sites are similar to those predicted by fracture and fragmentation theory, which further argues that these distributions are being dominantly controlled by the initial fracture and ...

Alterations in petrophysical and mechanical properties due to basaltic ...

2023.12.8  Basaltic lava typically has a pumiceous or spongy texture with secondary minerals (calcite, chlorite, and zeolite) contained in supercritical CO 2 filling the steam void (Fig. 3a) via dissolution of main minerals in the rock matrix and their consequent precipitation as described in Eqs. ()–()Basalt is an ideal CO 2 trap due to its chemical makeup and partially

Igneous Rocks - Types, Properties, and Examples - Science

2024.1.31  1. Felsic Igneous Rocks. Definition: Felsic rocks are rich in silica (over 65%) and contain a high proportion of lighter minerals like quartz and feldspar.The term “felsic” derives from “feldspar” and “silica”. Characteristics: These rocks are generally light in color, ranging from white to pink or light grey.They have a high content of aluminum, potassium, and sodium.

Basalt: Composition, Properties, Types, Uses – Geology In

3 天之前  Basalt Properties . Color: While typically described as black, basalt can exhibit a range of hues due to variations in mineral composition and oxidation. Shades of grey, green, and even reddish-brown are possible. Texture: Basalt exhibits a wide range of textures, from fine-grained and aphanitic (almost glass-like) to coarse-grained and porphyritic (containing larger crystals

Basalt Definition, Properties, Facts Britannica

2024.10.21  Minerals of the feldspathoid group occur in a large number of basaltic rocks belonging to the alkali group; nepheline, analcime, and leucite are the commonest, but haüynite is occasionally present. If nepheline entirely replaces feldspar, the rock is known as nepheline-basalt; if the replacement is only partial, the term nepheline-basanite is used. . Similarly, there

Basanite: A Fine-grained Mafic Volcanic Rock - Geology Base

2023.9.22  Basanite is a silica-poor, fine-grained, dark-colored volcanic rock. Here is its appearance, composition, formation, and where it is found. ... Basanite rock forms when silica-poor basaltic magma quickly cools on or near the Earth’s surface. The fast cooling impedes the growth of large mineral crystals. Thus, this rock has a fine-grained texture.
