The generation of hematite in these Clinton-type iron ores has been shown [15,16] to be associated with extensive re- placement textures of calcitic fossil fragments,Electrical conductivity (or resistivity) is a bulk property of material describing how well that material allows electric currents to flow through it. Resistance is the measured voltage divided by the current. This is Ohm's Law. Resistance will change if the measurement geometry or volume of material changes.

Hematite or hematitic sandstone, which yield red or orange powders, were also used. The closest sources for limonite are in north Louisiana or coastal Mississippi, while sandstone could be obtained from central and north Louisiana or the Mississippi coast.Fig. (1) displays the different conductivity properties at different conductor concentration of hematitic sandstone mixture at various frequencies. Conductivity displays frequency dependence with most of the specimens which is in correspondence with the universal power-law [22].In the condition of pure sand sample it is supposed that the pores are fully loaded with air.Chemical names for rust include iron oxide, ferric oxide and hematite. The substance is also known by its chemical formula, Fe2O3, which represents the two elements–iron and oxygen–that compose rust.The term 'hematite' itself might not be familiar to everyone, but its rusty red color definitely is. Sandstones are often reddish. This is because sand grains are coated with fine-grained hematitic powder. If soil is reddish, then it is also because of hematite. Even red granite owes its color to this mineral.and 3B) or fl aser-bedded hematitic sandstone that grades into hematite-rich oncoid rudstone (Figs. 2 and 3A). Hematite in the sandstone oc-curs as cement and as rounded reworked intra-Hematite is one of the most common minerals. The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals. Non-crystalline forms of Hematite may be transformation s of the mineral Limonite that lost water, possibly due to heat. Chemical Formula.
