Lake Tikub is a maar or a low-profile volcano created by phreatomagmatic eruption or the interaction between groundwater and magma underneath the Earth's surface. Like the seven lakes in the city of San Pablo, Laguna, which is about 15 kilometres (9.3 mi) away, the lake is one of the monogenetic volcanoes located in the Laguna Volcanic Field.
Magma chamber. A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. [1] If the magma finds a path to the surface, then the result will be a volcanic ...
Dacite (/ ˈdeɪsaɪt /) is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained (aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz.
Cirrhilabrus shutmani, also known as the magma fairy wrasse, was discovered by RVS Fishworld in 2016 living around the Didicas Volcano in the Babuyan Islands of the Philippines. The magma wrasse belongs to the family of ' Labridae ', a colourful species of tropical and subtropical fish. The magma wrasse is found in tropical coral reef, within ...
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 ...
Cryovolcano. A cryovolcano (sometimes informally referred to as an ice volcano) is a type of volcano that erupts gases and volatile material such as liquid water, ammonia, and hydrocarbons. The erupted material is collectively referred to as cryolava; it originates from a reservoir of subsurface cryomagma. Cryovolcanic eruptions can take many ...
Applications. The magma supply rate is used to infer the behaviour of volcanic systems which erupt periodically, as well as to describe the growth of the continental crust and of deep-seated magmatic bodies such as plutons. [3] Magma output is usually larger in oceanic settings than in continental ones, and basaltic volcanic systems produce ...
Description. The northern redbelly dace is a minnow about 55 mm long with two dusky, longitudinal stripes along its sides under an iridescent silver back. The top stripe often becomes broken into dots behind the dorsal fin. Small, almost invisible scales cover its body. The lower sides of its body are white, yellow, or silver.
