- n. A buff to gray windblown deposit of fine-grained, calcareous silt or clay.
Century Dictionary and Cyclopedia
- n. In geology, originally, a certain loamy deposit in the valley of the Rhine; now, by extension, any detrital accumulation more or less resembling the original loess occurring in other parts of the world. The loess is a very fine loam, very homogeneous in character, showing hardly any indication of stratification, and containing in numerous localities large quantities of land and fresh-water shells, as well as bones of land-animals. In northern China it covers a vast area and is developed to a great thickness, and, being deeply eroded by the rivers, has given rise to a very remarkable topography. In the regions where the loess occurs it is the most recent of the formations. The theories of its origin are numerous, and the subject is one of great complexity, so that “some skilful geologists, peculiarly well acquainted with the physical geography of Europe, have styled the loess the most difficult geological problem.” (Lyell.) Much that is called loess by some geologists is certainly river-mud deposited in the ordinary manner. Lyell connects the loess of the Rhine valley with glacial action; and Richthofen considers it as beyond dispute that the loess of China is a subaërial deposit, borne by the wind to its present resting-place.

“These dirt-cliffs, or "loess," to give them their scientific name, are remarkable banks of brownish-yellow loam, found largely in Northern and Western China, and rising sometimes to a height of a thousand feet.”
