Range of Theraphosinae The Theraphosinae are a large subfamily of Mygalomorphae spiders in the family Theraphosidae found primarily in the Neotropical realm . Genera
A contact can be formed during deposition, by the intrusion of magma, [2] or through faulting or other deformation of rock beds that brings distinct rock bodies into contact. [ 3 ] The geologic subdiscipline of stratigraphy is primarily concerned with depositional contacts, [ 4 ] while faults and shear zones are of particular interest in ...

Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
Theraphosa is a genus of South American tarantulas that was first described by Charles Athanase Walckenaer in 1805. The Theraphosa spiders are some of the largest known to science.
Contact metamorphism occurs typically around intrusive igneous rocks as a result of the temperature increase caused by the intrusion of magma into cooler country rock. The area surrounding the intrusion where the contact metamorphism effects are present is called the metamorphic aureole , [ 44 ] the contact aureole , or simply the aureole. [ 45 ]
Another main type of metamorphism is caused when a body of rock comes into contact with an igneous intrusion that heats up this surrounding country rock. This contact metamorphism results in a rock that is altered and re-crystallized by the extreme heat of the magma and/or by the addition of fluids from the magma that add chemicals to the ...
Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. It does so through magmatic activity or igneous activity, the production, intrusion and extrusion of magma or lava. Volcanism is the surface expression of magmatism.
