Sedimentary Rocks Notice in the rock cycle (Figure 2.8) that weathering processes disintegrate or decompose rocks at or near the surface. Accordingly, rocks are broken into smaller particles of gravel (>2 mm), sand (1/16–2 mm), silt (1/256–1/16 mm), and clay (2 mm

if oil shale warms to temperatures of greater than about 90C, the kerogen molecules break down to form oil and natural gas molecules. At temperatures over 160C, any remaining oil breaks down to from natural gas, and at temperatures over 250C, organic matter transforms into graphite. Thus, oil itself forms only in this narrow range of temperatures.

We had a stope that was 600 feet long and maybe 400 feet wide and over 200 feet high. That was all open space after the ore body was mined. That kind of mining is somewhat dangerous because you don't know when rock turns loose on the top, and so it's dangerous to walk across the floor of the stope, and so most of the mining was done in the walls.
