Geological
In geology, debris usually applies to the remains of geological activity including landslides, volcanic explosions, avalanches, mudflows or Glacial lake outburst floods (Jökulhlaups) and moraine, lahars, and lava eruptions. Geological debris sometimes moves in a stream called a debris flow.
In forests, coarse woody debris (CWD or CWH) refers to dead trees, left standing or fallen, and the remains of branches on the ground.
In streams and rivers, large woody debris (LWD) are the logs, sticks, branches, and other wood.
In mining, debris called attle usually consists of rock fragments which contain little or no ore.

Famous quotes containing the word geological:
“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”
—Ralph Waldo Emerson (1803–1882)
