Such is the story of an Arkansas man who drank so much iced tea that it led him to develop kidney failure. Three Arkansas doctors described the case in a letter published by the New England Journal of Medicine this week.
What is Marble? Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. Limestone is mostly calcite or calcium carbonate, CaCO 3. Dolomite CaMg(CO 3) 2 is related to limestone but is rich in magnesium.Marble has a uniform texture (non-foliated).t can be most any color including white, black, reds, greens, and more. It is usually course grained though fine-grained marble is found in some places and is highly prized for creating sculptures. Marble is used as building materials for its strength and beauty.
