|An example of a monomineralic rock is quartzite, which is composed of only quartz. An example of a polymineralic rock is granite, which is typically composed of quartz, feldspar, and mica.|

|Then what about Pure gypsum and Magnesite?|
|Shalu said: (Mar 28, 2014)|
|Magnesite is a mineral not a rock and pure gypsum is also a mineral (composed of sulphate i.e. CaS04.2H20).
Quartzite is monomineralic consisting quartz, whereas granites have quartz, feldspar & mica.
|Yadnesh said: (Sep 18, 2014)|
|Polymineralic means having more than one mineral.
These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals.
|Rash said: (Jan 9, 2015)|
|Composition of granite:
SiO2 72.04% (silica).
Al2O3 14.42% (alumina).
|Civilx said: (Mar 12, 2015)|
|Granite consists of QUARTZ, MICA, FELDSPAR.|
|Venkatesh said: (Mar 20, 2015)|
|Granite consists of Quartz, Mica, Feldspar.|
|Viswa said: (Jul 8, 2015)|
|Granite is a material which is hard and durable so it is known as polymineralic.|
|Veerendra Kumar said: (Jul 27, 2015)|
|Polymer rock is a very hard and durable.|
|Yuvaraj said: (Sep 15, 2015)|
|Granite is an igneous Rock.|
|Alagucivil said: (Sep 19, 2015)|
|What is quartz & mica?|
|Srinivas said: (Oct 12, 2015)|
|This rock is formed due to solidification of magma below the earth surface.|
|Jyothi said: (Dec 19, 2015)|
|Polymineralic rock means two or more minerals.
It consists of quartz, feldspar and mica.
|Nawaz Ikram said: (Dec 24, 2015)|
|Poly means more than 2 (bi) mineralic means composed mineral. Hence polymineralic rock means a rock composed of more than 2 minerals.
Composition of typical granite is Quartz, feldspar* and mica.
* is the most abundant mineral on the earth crust.
|Bhavesh said: (Apr 30, 2016)|
|Polymineralic means two are more mineral, which consists of one mineral.|
|Samim said: (Oct 2, 2016)|
|What is the different between mineral and rock?|
|Imran said: (Oct 24, 2016)|
|Gneiss, Basalt, Trape and feldspar rock.|
|Rony said: (Nov 6, 2016)|
|Granite is the rock which is made of more than two minerals.|
|Sandeep Kamble said: (Nov 17, 2016)|
|Which content present in granite & where excessive use of this, whether this is durable or not?|
|T.Ganai said: (Nov 19, 2016)|
|An example of a monomineralic rock is quartzite, which is composed of only quartz.
An example of a polymineralic rock is granite, which is typically composed of quartz, feldspar, and mica. The three basic rock types are igneous, metamorphic, and sedimentary.
|Lopamudra said: (Nov 29, 2016)|
|Granite is a polymineralic rock.
Polymineralic rocks are complex as the various minerals within the rock have different deformational behaviours.
|Jyoti said: (Jul 20, 2017)|
|What is Monomineralic means?|
|Arti said: (Jul 20, 2017)|
|What is the basic difference between monomineralic rock and polymineralic rock?|
|Kartikay said: (Aug 1, 2017)|
|What is polyminelaric rock?|
|Rohith said: (Aug 11, 2017)|
|What about magnesite?|
|Sandeep Maurya said: (Sep 13, 2017)|

|Mahesh said: (Dec 25, 2017)|
|What about the quartz sand?|
|Bhuvanesh said: (Jun 8, 2018)|
|What is the polymeric rock?|
|Niraj Kumar said: (Jul 5, 2018)|
|Quartz sand is mineral not a rock.|
|Sandip Sau said: (Jul 16, 2018)|
|Monomineralic rock is quartzite and polymineralic rock is granite.|
|Emran Khan said: (Sep 3, 2018)|
|Granite is a polymineralic rock because the main composition of granite is Sillica, mica, quarts.
So granite is polymineralic rock.
|Dhana said: (Oct 18, 2018)|
|Granite is a polyminerallic igneous rock which consists of minerals like quartz, feldspar and mica.|
|Mukesh Yadav said: (Jun 27, 2019)|
|Granite = mica, felspar, quartz, amphibole.
Pure gypsum = only mineral of sulphates.
Magnesite = mineral which has nickel, iron, cobalt, manganese as an admixture.
|Mahesh said: (Apr 7, 2020)|
|It Consists of More than one rock.|
|Bhumika said: (Jul 21, 2020)|
