Impurities in marble.

The many colours of marble are induced when impurities get caught in the structure of the marble during formation. What is marble veining. In addition to the major constituents marble can have many different mineral impurities of various percentages. In pure form marble consists of calcium carbonate calcite and is sparkling white.

Impurities produce pale gray brown or variegated colored rock. Marble that contains impurities such as clay minerals iron oxides or bituminous material can be bluish gray pink yellow or black in color. Mineral impurities in marble can include quartz tremolite actinolite chert garnet biotite muscovite microline talc and fosterite. This is a question that roams the landscape of the stone industry in 2018 and has been out there for decades if not centuries.

There are an enormous variety of impurities that can become trapped in the marble. Marble of extremely high purity with a bright white color is very useful. Marble is a metamorphic stone formed by subjecting limestone to heat or pressure. Chert garnet hematite mircroline talc fosterite muscovite biotite termolite actinolite and quartz.

Perhaps the best plan here is to develop a brief understanding of marble and then move on to veins and veining. Impurities give marble its individuality. The marble that contains impurities such as clay minerals iron oxides or bituminous material can be bluish gray pink yellow or black in color.
