The Strata MARS II is an automatic pipeline system for the pneumatic transfer and storage of bulk rock dust in underground coal mines. It is designed to distribute large quantities of rock dust underground, greatly simplifying the process and reducing the amount of man-power required to accomplish the task.

The hill in which it existed is not high enough to take in the bed of carboniferous coal found in a horizontal stratum about 250 feet above the locality. In fragments of the impressed rock, Lea found fossils of primitive jointed plants - the type which made its .
That sediment eventually fossilizes and becomes rock. This natural process of coal formation takes up to 400 million years to accomplish. Anything that is found in lumps of coal or in coal seams during mining, had to have been placed or dropped into the vegetation before it was buried in sediment.
Rock strata are studied, a few index fossils are located (when they can be found at all), and each stratum is then given a name. Since the strata are above, below, and in-between one another, with most of the strata missing in any one location,—just how can the theorists possibly "date" each stratum?
Coal is basically a sedimentary rock, a combustible sedimentary rock to be precise, that is found in rock strata in layers which are referred to as 'coal beds' or 'coal seams'. It is primarily made up of carbon, but also has significant amount of hydrogen and sulfur in it.

Coal beds form in parallel strips to the earth's surface: the deeper the bed, the harder the coal. Large areas of coal are called coal reserves.
What is Coal? Coal is an organic sedimentary rock that forms from the accumulation and preservation of plant materials, usually in a swamp environment. Coal is a combustible rock and, along with oil and natural gas, it is one of the three most important fossil fuels.Coal has a wide range of uses; the most important use is for the generation of electricity.
Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It is formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams.

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.

If a single mammalian fossil were found in situ in precambrian rock strata, evolution would be falsified. The rock strata slopes slightly upwards to the south, giving the highest cliffs on the south and some beaches to the north. As is the case with all anticlines, older rock strata are found .
Coal is found under the ground in "coal beds." It is considered a sedimentary rock and is black or brownish-black in color. It is specifically found in rock strata and appears in layers or veins.
