Exploring for Coal Layers in Kentucky

Understanding Coal Exploration in Kentucky

Coal exploration in Kentucky involves prospectors locating a horizontal coal layer hidden under the soil and regolith on a moderate slope. In this process, it is important to identify the distinctive quartz sandstone bed that lies beneath the coal layer. By studying the rock fragments as they move up the slope, the prospectors can anticipate finding the coal just below the lowest piece of sandstone in the regolith.

Explanation:

In this scenario, the coal layer is concealed beneath the soil and regolith on a moderate slope. The prospectors are aware that beneath the coal layer, there is a distinct quartz sandstone bed. By analyzing the rock fragments as they ascend the slope, they will likely encounter the coal just below the lowest piece of sandstone in the regolith. This positioning indicates the proximity of the coal layer to the sandstone bed, aiding in the exploration process and the extraction of coal resources in Kentucky.
