Wet table, water table The Wilfley Table is commonly used for the concentration of heavy minerals from the laboratory up to the industrial scale. It has a traditional shaking (oscillating) table design with a riffled deck. [ 1 ]
Current ripple marks, unidirectional ripples, or asymmetrical ripple marks are asymmetrical in profile, with a gentle up-current slope and a steeper down-current slope. The down-current slope is the angle of repose, which depends on the shape of the sediment.
The weather rock or weather stone is a humorous display that pokes fun at the intricate technology used in modern weather forecasts, as well as the fact that their accuracy is less than perfect. A rock is typically hung from a tripod and accompanied by a sign indicating how to read it. [ 1 ]
Wave ripple or symmetric ripple, from Permian rocks in Nomgon, Mongolia.Note "decapatation" of ripple crests due to change in current. In sedimentology, wave-formed ripples or wave-formed ripple marks are a feature of sediments (sandstones, limestones, siltstones) and dunes.
Acid Mothers Temple & the Melting Paraiso U.F.O., commonly shortened to Acid Mothers Temple or AMT, is a Japanese rock band, the core of which formed in 1995. [4] The band is led by guitarist Kawabata Makoto and early in their career featured many musicians and offshoot groups and collaborations, but by 2004 the line-up had coalesced with only a few core members and frequent guest vocalists.
Laterite in Sơn Tây, Hanoi, Vietnam. Francis Buchanan-Hamilton first described and named a laterite formation in southern India in 1807. [4]: 65 He named it laterite from the Latin word later, which means a brick; this highly compacted and cemented soil can easily be cut into brick-shaped blocks for building.
Harling as a process covers stonework using a plastering process involving a slurry of small pebbles or fine chips of stone. After a wall is complete and has been pointed and allowed to cure then a base of lime render is applied to the bare stone. While this render is still wet a specially shaped trowel is used to throw the pebbles onto the ...
In most bottom-of-bed examples, the cracks are the part that sticks out most. Bottom-of-bed preservation occurs when mudcracks that have already formed and are completely dried are covered with fresh, wet sediment and are buried. Through burial and pressure, the new wet sediment is further pushed into the cracks, where it dries and hardens.
