Overburden is the name given to the body of earth and rock which lies above a deposit of wanted ore or coal. In open cast mining, it must be removed before the target material can be recovered.
Overburden ,.,. if a guy said I'm overburdened.. then he means that his inventory ( bags, pockets, backpack are FULL and he is too heavy to run.

I often visit a cliff that has an overburden of Loess. So, yes, you can find Loess on a cliff. Rather, on top of a cliff.
Pillow basalt is formed when lava extrudes from the ocean floor - perhaps into a sediment overburden (?) - such that each bolus of lava is separate from the others.
Sedimentary rocks can be found anywhere rock particles, clay, and organic matter has deposited itself and lithified from overburden pressure or chemical precipitation from a saturated solution. Sedimentary rock covers 75% of the surface of the Earth's continents.
Deep Underground (I think)
In geology, overburden soil is the soil and other material which lies over a rock formation or mineral deposit.
Overburden or lithostatic pressure.

Overburden or lithostatic pressure.
Through increased overburden pressure.
We divide the overburden thickness by ore thickness to get the stripping ratio For example if we have an overburden thickness of 80m and ore thickness of 50 m , then the stripping ratio will be: 80/50= 1.6
The main force is weight of overlying rocks , called overburden, which puts overburden pressure on sediments and make them compress and compacts
Overburden tons/ore tons

Coal can be found in certain locations where it is exposed at the surface via erosion of the overburden. Most often, it is not.
Sometimes called "strip" mining- soil and overburden is stripped away, exposing the coal.
