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 eɪ ˈ ɪ 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.

4. Alkali feldspar granite - Wikipedia

   en.wikipedia.org/wiki/Alkali_feldspar_granite

   Alkali feldspar granite, some varieties of which are called 'red granite', [1] is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals. [2] [3]

5. Trachybasalt - Wikipedia

   en.wikipedia.org/wiki/Trachybasalt

   Trachybasalt is a volcanic rock with a composition between trachyte and basalt. It resembles basalt but has a high content of alkali metal oxides . Minerals in trachybasalt include alkali feldspar , calcic plagioclase , olivine , clinopyroxene and likely very small amounts of leucite or analcime .

6. Laboratory glassware - Wikipedia

   en.wikipedia.org/wiki/Laboratory_glassware

   Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.

7. Laboratory flask - Wikipedia

   en.wikipedia.org/wiki/Laboratory_flask

   Schlenk flask, which is a spherical flask with a ground glass opening and a hose outlet and a vacuum stopcock. The tap makes it easy to connect the flask to a vacuum-nitrogen line through the hose and to facilitate the carrying out of a reaction either in vacuum or in an atmosphere of nitrogen.

8. Volcanic rock - Wikipedia

   en.wikipedia.org/wiki/Volcanic_rock

   Basalt is a very common volcanic rock with low silica content. Rhyolite is a volcanic rock with high silica content. Rhyolite has silica content similar to that of granite while basalt is compositionally equal to gabbro. Intermediate volcanic rocks include andesite, dacite, trachyte, and latite. [citation needed]

9. Shaker (laboratory) - Wikipedia

   en.wikipedia.org/wiki/Shaker_(laboratory)

   A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology. A shaker contains an oscillating board that is used to place the flasks, beakers, or test tubes.
