An intrusive body is described as multiple when it forms from repeated injections of magma of similar composition, and as composite when formed of repeated injections of magma of unlike composition. A composite dike can include rocks as different as granophyre and diabase .

WebbCharacteristics A body of intrusive igneous rock which crystallizes from magma cooling underneath the surface of the Earth is called a pluton.If the pluton is large, it may be called a batholith or a stock depending on the area exposed at the surface. If the body has an exposed surface area greater than 100 km2, then it’s a batholith, otherwise it’s a stock. floraworld rasenkanteWebbThe granitic intrusive bodies that generate these deposits are formed later as post-orogenic intrusions that are relatively reduced chemically, alkaline-tending and volatile-rich. These plutons fracture the surrounding rocks as they are intruded and the parallel fractures created give rise to the sheeted vein systems that are characteristic of these deposits. florayerWebbA pinhole camera has a small circular aperture of diameter D.
