The passage of Hurricane Isabel in Pennsylvania resulted in $160 million in damage (2003 USD, $206 million 2016 USD) and 2 indirect deaths in Pennsylvania. One person suffered from carbon monoxide poisoning, believed to be caused due to improperly ventilated generators in an area affected by the power outages.
Limestone is used as a filler in a variety of products, including paper, plastic, and paint. The purest limestone is even used in foods and medicines such as breakfast cereals and calcium pills. Limestone is also the raw material for making lime (CaO) that is used to treat soils, purify water, and smelt copper.lthough limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a truly versatile commodity.
Pure limestone is made of calcium carbonate. Limestone often contains variable amounts of silica in the form of chert or flint, as well as varying amounts of clay, silt and sand as disseminations, nodules, or layers within the rock.The primary source of the calcite in limestone is most commonly marine organisms.These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pelagic ooze or alternatively is conglomerated in a coral reef (see lysocline for information on calcite dissolution).ere, it decays and becomes a part of the rock known as limestone. So, limestone is made of decayed calcium, or calcite.   +++   Almost-but a chemical element cannot decay! The primary mineral of this sedimentary rock is calcite, calcium carbonate, which is a chemical compund (CaCO3).
