What Is The Grain Size Of Marble

The evaluated mean grain size of samples were given in table 2for sedimentary marble samples thecomparison of the experimental and the evaluated mean grain size results have been shown in fig 8.

What is the grain size of marble.

Evaluated mean grain size of sedimentary marble samples by using 4 mhz probe. Physical properties of rocks are used to identify the type of rocks and to discover more about them. Grain size medium grained. By using this equation we calculated mean grain size of samples which are given in table 3.

Longer the time it takes to cool larger will be the grain size and vice versa what makes a marble rare. Grain size depends upon the cooling rate as written below. There are 2 000 3 000 grains to the square centimeter 0 1550 square inches. Ultrasonic velocity mean grain size graph of marble samples.

Sedimentary s1 s2 s3 s4 s5 s6 experimental mean grain size µm. Where the marble is in direct contact with the intrusive granite the most consistent change in the marble is that it becomes extremely coarse grained with the grain size in the contact zone being 10 mm to 20 mm 0 3937 0 7874 inches. Hardness hard although component mineral is soft calcite is 3 on moh s scale of hardness. In this graph correlation coefficient is found to be 0 99966 and equation of the correlation line is found as y 25 814 x 3570 7.

Colour variable pure marble is white but marble exists in a wide variety of colours all the way through to black.
