... to both the climb angle of the bed form and the climb angle of the river channel. Deposition in a meandering stream can produce the classic Allen sequence (1965), typified by a scour-based point-bar sequence, as shown in Figure 6d . The Allen sequence consists of a sandy member (channel-fill...

Texture, structures, and stratigraphic position indicate that sediment probably is natural-levee or crevasse-splay deposit. B . Cyclic unit of type...

... is elusive. Although linear progression of time as an arrow in a 3D space gives us a simplified version of understanding time, formulation of a united spacetime concept in general relativity ( Einstein 1915 ) broke the traditional notion of time as an arrow progressing only in one direction. Similarly...

...David B. Loope Abstract In south-central Utah, eolian cross-strata of the Escalante Member of the Entrada Sandstone contain inclined, cylindrical burrows up to 63 cm in diameter and 305 cm long. Of the 14 large tunnels located during this study, 12 descend from second- and third-order bounding...

Within a single horizon, thickness of the individual sandstone layers increases upward. The sandstone layers show parallel lamination, climbing ripple lamination and ripple...

... electron microscopy (TEM) investigation of the run products indicates that dislocation glide, assisted by climb within grains and dynamic recrystallization for grain-boundary strain accommodation, is the dominant deformation process in pyrope. Both synthetic-and natural-pyropes’ stress and strain-rate data...

The southeast face of El Capitan has continuous and steep exposure, fully visible from the valley floor, which is crossed by over 70 named climbing routes and is thus more accessible for observation, mapping, and sampling than other km-tall...

... ). Siliciclastic sediment waves in slopes are thought to form in association with sediment gravity flows which have reached Froude supercriticality (Fr > 1) because sediment-wave crests climb upslope and upflow ( Symons et al. 2016 ), which is a hallmark signature of supercritical-flow bedforms such as cyclic...
