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 limestone that was heated longer and transformed in the earthâs crust. It is often mistaken for granite, and visa versa, as the two have the same general look, weight and are used for similar purposes. Luckily, they have several distinct qualities that help tell them apart.
