Coal bed formation in Antarctica is possible through the accumulation and burial of plant material in swamps during ancient warm periods in the Earth's history. Over millions of years, the plant material undergoes compaction and chemical changes, forming peat and eventually coal. Antarctica has a history of relatively warm climates in the past, allowing for the formation of these coal beds that we see today.
What else can I help you with?
What geologist wants to locate a horizontal coal bed on a soil-covered slope where soil creep is active A distinctive sandstone bed underlies the coal bed On the basis of weathered sandstone fragm?
A geologist would typically use methods such as surface mapping, seismic testing, and borehole drilling to locate a horizontal coal bed on a soil-covered slope where soil creep is active. The distinctive sandstone bed underlying the coal bed can serve as a helpful marker for geologists to better identify and locate the coal bed in such challenging geological conditions. Additionally, analyzing weathered sandstone fragments can provide valuable insights into the composition and potential presence of the coal bed beneath the soil-covered slope.
How a coal seam might be used as a key bed?
A coal seam can be used as a key bed in stratigraphy by acting as a recognizable and widespread marker layer in the rock sequence. Key beds help correlate different rock layers in different locations based on the consistent presence of a specific marker bed, such as a coal seam, allowing geologists to establish the relative ages of rocks in various areas.
What are coal beds?
Coal beds are layers of hardened plant material that have been compressed over millions of years underground. These beds are rich in carbon and are one of the main sources of coal used for energy production. Coal beds are often found in sedimentary rock formations.
How does a coal seam might be used as a key bed?
A coal seam can be used as a key bed in geology to help determine the relative age of surrounding rock layers through the principle of superposition. Key beds are distinctive, widespread, and easily recognizable rock layers that can be correlated across different locations. By identifying a coal seam as a key bed, geologists can use it as a reference point to establish the relative ages of other rock layers in the area. This can help in understanding the geological history and sequence of events in a particular region.
Why is coal an unusual sedimentary rock?
First of all coal is not an unusual sedimentary rock, it is very abundant for the time being. The following is a tutorial from the supplied web site: Coal is clearly made up of lots of compressed bits of dead plants. But when we walk around in the world we usually see old bits of wood and leaves decaying and rotting away (that is, getting eaten by bacteria, insects, and all sorts of organisms involved in decay and recycling of organic matter). For thick layers of plant stuff to get fossilized as coal, something must be going on. Coal Formation starts with accumulation of organic matter (bits of dead plants) in a low oxygen setting such as a peat bog. The organic matter accumulates and forms a bed of peat. The peat bed gets buried by other sediments and under heat and pressure begins to transform to a low grade coal - a Lignite. More heat and pressure further metamorphose the lignite into Bituminous coal. Even more heat and pressure metamorphose the bituminous coal into a nice hard shiny Anthracite. Coal is usually classified into three grades: Lignite, brown coal; Bituminous coal, soft coal; and Anthracite, hard coal. Anthracite is dense, nice and hard, and shiny. The first step in the formation of coal is the accumulation of plant debris in low oxygen conditions, such as in this damp low spot on a moor. Peat exposed to heat and pressure from burial beneath other sediments becomes compressed and chemicaly changes into low grade coals such as this lignite, and under further heat and pressure is converted to higher grade coals. The pressure from overlying sediments that bury a peat bed will compact the coal. Peats transform to low grade lignites when they are compressed to about 20% of their original thickness. Lignite typicaly transforms to bituminous coal as it is compressed further and heated to between 100 and 200°C. This drives much of the water and other volitiles from the coal. Longer exposure to elevated temperature will further drive volatiles from the coal, and drive chemical reactions that produce anthracite. Anthracite coals are typicaly compressed to 5-10% of the orginal thickness of the peat bed, and contain less than 10% water and other volatiles.
How do plant fossils and bed of coal support the idea that Antarctica once was warmer that it is today?
Plant fossils and coal seams could only have formed if Antarctic had once been warmer (further north).
Does coal oil same as fossil fuels?
I believe you mean coal bed gas or coal bed methane which is a fossil fuel.
What does CBM abbreviate?
coal bed methane

Where are groundhogs found?
Groundhog's are ususally found in tropical rainforests and in Antarctica. Sometimes they are found under your bed.

Is it possible that the bed is too soft for your comfort?
Yes, it is possible that the bed is too soft for your comfort.
What is the layer of coal between rocks called?
The layer of coal between rocks is called a coal seam or coal bed. This layer forms over millions of years from compressed plant material.
What causes clinker formation in boiler?
Clinkers, also known as slag, consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Boiler operators consider clinkers to be miserable stuff
