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 has been pressed by the earthâs pressure to produce a hard substance of crystals and beautiful lines and colors. Marble can have nearly any coloring, from blacks to white, and with a number of fantastic colors in between such as green and pink.ranite is an igneous rock (formed by heat) found deep within the Earth's crust. Once quarried, cut, polished, & sealed granite is nearly impervious to scratches, heat, etching, staining, or weathering. It is truly one of Mother Nature's most versatile and beautiful creations.
