.... Facts obtained from laboratory experiments help explain rock disintegration by frost action and also the movements of rock waste that result from the freezing of water-saturated soils. Bedrock gravels of stream valleys and coastal plains are buried under thick silt deposits, usually called “muck...

...T. A. Fraser; C. R. Burn Abstract Organic-rich "muck" deposits, which blanket auriferous gravels in the Klondike area, Yukon Territory, comprise two principal stratigraphic units: ( i ) a silty Late Pleistocene deposit, and ( ii ) Holocene organics lying unconformably on the silt. The deposits...

Early-formed fractures are chiefly narrow (<4 mm wide) cracks up to several decimeters long which are sub-perpendicular to bedding and which are filled by slightly darker non-fibrous colorless microquartz. Breccias are formed of angular novaculite clasts in a black organic-rich siliceous...

In the adjacent Inner Hebrides Basin, represented by the Strathaird (Skye), Eigg and Muck exposures, a sequence of alternating carbonate-shale deposits accumulated, virtually free of clastics coarser than silt grade, here termed the argillaceous limestone facies...

In modern analogous peat-forming environments in tropical southeastern Asia, accumulations of low-ash and low-sulfur domed peat are dependent on high rainfall, which contributed little...

The sand in most localities contains 10 per cent of silt and clay but locally as little as 5 or as much as 40 per cent. In general the beach sands examined contained much less silt and clay than the oil sands. However...
