Rocks and Minerals in atomic number 49 - Assignment display caseAdditionally, minerals hand in abundance at heart this state. Estimates be that Indiana has approximately 100 unalike minerals, although early(a) minerals exist in scarcity. This implies the state has more than 100 minerals considering the scarce mineral deposits that are present within the region.Despite the huge deposits of minerals across Indiana, only some minerals occur in large quantities. The most replete of the minerals in Indiana include calcite, clay minerals and quartz (Smith, Brookley and McGregor 12). The largest percentages of the minerals that are present in Indiana are widely dispersed while others are totally covered by the earth crust. Therefore, this makes economical habit of these minerals impossible, especially in large-scale mining. Additionally, the process of mining and searching for these minerals can be uneconomical since the minerals occur sparingly.Calcite occurs in Indiana as one of the most abundant minerals. It is usually present in different rock layers. The mineral is considered the largest carbon depository and takes up the form of limestone coupled with marble. Limestone is generated either through chemical substance precipitation of CaCo3 or changes that transpire on various constituents in the period that diagenesis occurs. Conversely, marble is generated in the represent that limestone gets exposed to towering temperature and pressure. Nearly all the calcite that is present in Indiana is colorless or possesses icteric and brown shades. Calcite has hexagonal shaped crystals in case they are visible to the eye. The calcite present in Indiana has crystals that bear other minerals such as pyrite although this phenomenon rarely occurs. Outstanding specimens of calcite and other related mineral deposits are present in Indiana, with some possessing large crystals (IGS1).The properties that calcite possesses makes the mineral exceptional during identificatio n thus making it easier to recognize the mineral.
