Amphibolite from Cape Cod, Massachusetts Garnet bearing amphibolite from Val di Fleres, Italy. Amphibolite (/ æ m ˈ f ɪ b ə l aɪ t /) is a metamorphic rock that contains amphibole, especially hornblende and actinolite, as well as plagioclase feldspar, but with little or no quartz.
The facies are named after the metamorphic rock formed under those facies conditions from basalt. [79] The particular mineral assemblage is somewhat dependent on the composition of that protolith, so that (for example) the amphibolite facies of a marble will not be identical with the amphibolite facies of a pellite.
They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distortion. Metamorphic rock can be formed locally when rock is heated by the intrusion of hot molten rock called magma from the Earth's interior. The study of metamorphic rocks (now exposed at the Earth's surface following ...
The video game industry is the tertiary and quaternary sectors of the entertainment industry that specialize in the development, marketing, distribution, monetization, and consumer feedback of video games. The industry encompasses dozens of job disciplines and thousands of jobs worldwide. [1] The video game industry has grown from niche to ...
The pressures exceed those of greenschist, blueschist, amphibolite or granulite facies. Eclogites containing lawsonite (a hydrous calcium-aluminium silicate) are rarely exposed at Earth's surface, although they are predicted from experiments and thermal models to form during normal subduction of oceanic crust at depths between about 45–300 km ...
According to IDC, mobile game revenue shot up 32.8% to $99.9 billion in 2020, while digital PC and Mac game spending jumped 7.4% to 35.6 billion. Home console game spending, meanwhile, soared 33.9 ...
Blastomylonites are coarse grained, often sugary in appearance without distinct tectonic banding.; Ultramylonites usually have undergone extreme grainsize reduction. In structural geology, ultramylonite is a kind of mylonite defined by modal percentage of matrix grains [clarify] more than 90%. [4]
Following 2024’s massive wave of layoffs across the video game industry, one in 10 developers say they were among those cut from AAA studios and indie outlets alike. According to the the Game ...
