n: 1. a body of coarse, poorly sorted sediments formed by the coalescence of alluvial or detrital fans along the flanks of a mountain range. 2. a similar body of turbidite sediments formed by the coalescence of submarine debris fans along the base of the continental slope.

n: 1. the change from a liquid to a thickened, curdlike state by chemical reaction.2. the combining of globules in an emulsion caused by molecular attraction of the surfaces.

the combination of bubbles or droplets in an emulsion to form larger bubbles or drops that will separate easier.

n: a system, chemical, device, or process used for breaking down an emulsion and producing two or more easily separated compounds (such as water and oil). Emulsion breakers may be (1) devices to heat the emulsion, thus achieving separation by lowering the viscosity of the emulsion and allowing the water to settle out;(2) chemical compounds, which destroy or weaken the film around each globule of water, thus uniting all the drops;(3) mechani- cal devices, such as settling tanks and wash tanks;or (4) electrostatic treaters, which use an electric field to cause coalescence of the water globules.

n: excelsior, used in emulsion treating to encourage coalescence.
