Chemical weathering of a granite stone sample from the.Electron Microscope. Three grains of feldspars are identified in the piece of granite stone and 29 points were selected on outer surfaces of these 3 grains of feldspar. The analyses were calculated on the basis of 32 O ions to study the intensity of insitu weathering of the grains of feldspar. The EDAX analyses show that grain I and II

Magma Mixing in a Granite and Related Rock.K-feldspar mantles Figure 2c, and plagioclase or quartz phenocrysts rimmed by biotite are common. Enclaves in the Siling granodiorite and alkali feldspar granite are typically ne-grained and equigranular to porphyritic. They are dark gray in color and range in size from 5cmto 10 cm in the longest dimension Figure 2d.
Graphic intergrowths of feldspars and quartz in some.Graphic intergrowths of alkali feldsparquartz, and plagioclasequartz, occur together in pegmatites in the eastern part of the Czechoslovak Moldanubicum. They form zones between the finer-grained wall zone and the central blocky feldsparquartz core. The normative Or-Pig-Q compositions of the graphic intergrowths and the Or-Ab-An contents of their feldspars show broad variations generally ...

1 Introduction Hindawi.Nepheline syenite is a light-colored alkaline igneous rock formed mainly of alkali feldspar and nepheline in appreciable amounts. It is similar in appearance to coarse-grained granite but characterized by absence of quartz. Nepheline syenite is an indispensible raw material in glass and ceramic industries.
Beneficiation Studies Of The Alkali Cobblestone Granite.Granite r n t is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly solidifies underground.It is common in the Earths continental crust, where it is found in various kinds of igneous intrusions.These range in size from dikes only a few inches across to
