  2. Calc-alkaline magma series - Wikipedia

    en.wikipedia.org/wiki/Calc-alkaline_magma_series

    The calc-alkaline magma series is one of two main subdivisions of the subalkaline magma series, the other subalkaline magma series being the tholeiitic series. A magma series is a series of compositions that describes the evolution of a mafic magma, which is high in magnesium and iron and produces basalt or gabbro, as it fractionally crystallizes to become a felsic magma, which is low in ...

  3. Tholeiitic magma series - Wikipedia

    en.wikipedia.org/wiki/Tholeiitic_Magma_Series

    The tholeiitic magma series (/ ˌ θ oʊ l i ˈ aɪ t ɪ k /) is one of two main magma series in subalkaline igneous rocks, the other being the calc-alkaline series. A magma series is a chemically distinct range of magma compositions that describes the evolution of a mafic magma into a more evolved, silica rich end member. Rock types of the ...

  5. Alkaline magma series - Wikipedia

    en.wikipedia.org/wiki/Alkaline_magma_series

    All alkaline series magmas are thought to have evolved from a primitive mafic alkaline magma, either an alkalic picrite basalt or an ankaramite. This evolves to an alkali olivine basalt or basanite. Thereafter the series branches to the sodic series, the potassic series, or the nephelinic, leucitic, and analcitic series. [1] [2]: Ch6

  6. Igneous differentiation - Wikipedia

    en.wikipedia.org/wiki/Igneous_differentiation

    It is worth reiterating that magma chambers are not usually static single entities. The typical magma chamber is formed from a series of injections of melt and magma, and most are also subject to some form of partial melt extraction. Granite magmas are generally much more viscous than mafic magmas and are usually more homogeneous in composition ...

  9. Punta del Cobre Formation - Wikipedia

    en.wikipedia.org/wiki/Punta_del_Cobre_Formation

    The rocks of the formation belong to the calc-alkaline magma series. [1] Rocks show intense hydrothermal alteration [1] and hosts significant copper and gold deposits and lesser amounts of zinc and silver. [2] The formation lies in a zone of small-scale mining that supplies the nearby Fundición de Paipote copper smelter. [3]
