The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization. Typically, marble is composed of the following major constituents: 3842% Lime (CaO), 2025% Silica (SiO2), 24% Alumina (Al2O3), % various oxides (NaO and MgO), and 3032% various carbonates (MgCO3 and others).
During marble mining, processing, cutting and polishing, more than 12 MT (million tons) of marble waste is produced in the state of Rajasthan, India, which is now a major environmental issue. The marble waste used in the present study was collected from Makrana marble mining, Rajasthan. The major mineral present in marble waste were calcite (CaCO3), dolomite (CaMg(CO3)2) and quartz (SiO2).
Makrana Marble. Basically Makrana is best quality of Marble. It has used in too many valuable places like The world famous Taj Mal In Agra, The famous Victoria Memorial of Kolkata, Raudat Tera in Mumbai and Jain Temple of Dilwara Temples in south Rajasthan are built from Makrana Marble and too many more places in this world not only in india.
Makrana Pure White Marble. Makrana Pure White Marble is one of the oldest and finest quality of marble. It needs no chemical reinforcement, no pin holes, no color change and no loss of is practically verified by the buildings and numerous temples, mosques, churches and monuments in India for over 1000 years now.
Marble Chemical Composition The chemical composition of the different varieties is almost the same, and it may therefore be given at once for the whole. The following is the analysis made by Professors Daniel and Wheatstone for the commissioners who selected the stone for the Houses of Parliament:
Makrana marble It is white in colour. (India) Murphy marble It is white in colour. XRF and XRD tests are often conducted in the analysis of marble and other stones. When any type of acid reacts with the marble stone, a corrosive chemical reaction occurs and that is known as etching.
Makrana marble Wikipedia
Makrana is the name of village which produce this quality .That is known as Dungri Marble. There are 150 Gangsaw established which are manufacturing marble slabs amp; tiles. More than 2500 marble
Makrana Marble, which is greatly used in residential housing and commercial structures to acquire their floors. It can be used by our valuable customers. Due to its distinctive characteristics such as outstanding design and amazing shine, the marble we offer is commonly addition, the marble we provide looks attractive.
One of the most impotent quality of Makrana marble is resistant to water seepage, because it contains 98 percentage of calcium carbonate 2 percent of impurities. Makrana Marble quarry are oldest one in India. After mining, these Marble stones are only used in cutting and chiselling. No other chemical treatments are applied on these.

Makrana marble is a metamorphic rock. It is a single deposit in India. The Makrana marble has 90 to 98 percent CaCo3.[citation needed] Demographics. As of 2001[update] India census[2], Makrana had a population of 83,289. Males constitute 52% of the population and females 48%.
petrograpic analysis can be arranged through most construction material laboratories. A comprehensive petrographic analysis will often suffice to answer many behavioral questions. Other, more sophisticated analyses performed in wellequipped chemical laboratories to determine exact chemical and trace element content can also be useful.
The water absorption of Makrana marble is said to be the lowest among all types in India, and the marble is claimed to contain 98 percent of calcium carbonate and only two percent of impurities, this property of Makrana marble helps it to stay the same proportion of white for a long period of time and because it contains 98 percent of calcium the polish of this marble is considered in the best.

#0183;#32;Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3).Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron minerals can give marble a pink, brown, gray, green, or variegated coloration.
#0183;#32;Raw material characterization Chemical analysis (XRF) Table 2 shows the chemical analyses of the raw materials as obtained from XRF analyses, whereas Table 3 presents the percent of free silica and organic matter of the two wastes. The loss on ignition obtained is significantly higher in case of marble waste than that of granite waste.
Makrana Marble Makrana is a town in the Nagaur district of Indian state of Rajasthan. Makrana is famous for the white stone as marble mined from the mines around it. It is said that the Taj Mal was built from Makrana marble. Makrana is a small town, but it has plenty of marble outcrops. Most of the residents in this town work as marble miners.
(1) Chemical Analysis. The chemical analysis, with an Atomic Absorption Spectrometry AAS, was performed according to the requirements of EN ISO 15586. The results of the chemical analysis, presented in Table 1, indicate that the marble powder is excessively rich in calcite (CaCO 3 = %), and it is devoid of all clay and organic matter.
Based on the satellite data analysis for the year 2003, the mining area of Makrana marble and Jodhpur sandstone has been estimated as sq. km and sq. km respectively.
