Biotite (hornblende) two-feldspar gneiss and (5) Fault br.
Jadeite jade consists of minerals of pyroxene, amphibole and feldspar groups.
Under P-stress, mobilization and utilization of structural K in gneiss and feldspar by maize Zea mays l.
Z-shaped superposed folds formed by nearly vertical gneiss and feldspar-quartz veins are widely developed in East Qinling Precambrian metamorphic rocks.
Symbiosis with acidic potassium feldspar, plagioclase, biotite.
The sherdscontain quartz, feldspar, calcspar and sericite as well as some charcoal.
The acidproof bricks with high performances were produced by using kaolin, quartz sand, refractory waste, K-feldspar and barium carbonate.
There are different sediment origins for Saximiao formation on both east and west sides of work area, shown in the distribution of feldspar content, carbonate rock cuttings and sandbody cycle.
The kaolinite dissolution from feldspar grow much mineral intercrystal porosity.
The reserves of iron, barium, antimony, silver, fluorite, potash feldspar, white mica and other20 minerals are of a considerable scale.
It's got lower aluminium and more magnesium relative to silicon, so it has a lower abundance of feldspar [minerals], and so it has clearly undergone a unique geological history.
Study on the reactive system of consisting of potash feldspar-phosphate rock-hydrochloric acid
In the course of weathering, the color of potash feldspar will change, and the red color of meat can be turned into grey and white.
The protoliths of quartz jadeitite include metamorphosed granite, trondhjemite, acidic volcanic rocks and feldspar-quartz sandstone.
The deposit is an alkali-feldspar granite type Ta deposit.
The Dashankeng gneiss located in the northeastern Dabie mountains is composed mainly of potassium feldspar, plagioclase and quartz with minor hornblende, biotite and allanite, belonging to monzonitic granitic in composition.
Early Yanshanian intrusions are mainly adamellite, biotite K-feldspar granite with small amount of granodiorite.
Experimental synthesis of 13x zeolite molecular sieve which is an important byproduct with high additional value in distilling potassium from potassium feldspar is studied in this paper.
granit is S-type and its evolution sequence might begranomonzonite → muscovite-granite(outcrop) → feldspar-granit →muscovite-granite(core);
