Physically, volcanic blocks damage local flora and human settlements. Ash damages communication and electrical systems, coats forests and plant life, reducing photosynthesis, and pollutes groundwater. [9] Tephra changes below- and above-ground air and water movement. Chemically, tephra release can affect the water cycle.
Rhyolite is an extrusive igneous rock, formed from magma rich in silica that is extruded from a volcanic vent to cool quickly on the surface rather than slowly in the subsurface. It is generally light in color due to its low content of mafic minerals, and it is typically very fine-grained ( aphanitic ) or glassy .
Dacitic magma was encountered in a drillhole during geothermal exploration on Kīlauea in 2005. At a depth of 2488 m, the magma flowed up the wellbore. This produced several kilograms of clear, colorless vitric (glassy, non-crystalline) cuttings at the surface. The dacite magma is a residual melt of the typical basalt magma of Kīlauea. [16]
Berynium is a minable isotope discovered by NEB (New Economic Block) at New Alamo on Sirius 6B on 16 July, AD 2064. Berynium is the solution to the world's energy crisis, as a spoonful of it can take you from Earth to Saturn in a single day. Mining it unfortunately releases lethal quantities of radiation and pollution.
Magma that cools slowly within a magma chamber usually ends up forming bodies of plutonic rocks such as gabbro, diorite and granite, depending upon the composition of the magma. Alternatively, if the magma is erupted it forms volcanic rocks such as basalt , andesite and rhyolite (the extrusive equivalents of gabbro, diorite and granite ...

Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form intrusions, such as batholiths, dikes, sills, laccoliths, and volcanic necks. [1] [2] [3] Intrusion is one of the two ways igneous rock can form. The other is extrusion, such as a volcanic eruption or similar event.
Vertical migration of magma is driven by gravity. Stoping occurs when blocks of wall rock material are transferred downward through a pluton. [1] [2] Stoping is an important emplacement mechanism in a variety of tectonic settings and has been widely used to explain discordant pluton contacts. [2]
