Abstract A non-biomineralized arthropod, Protocaris marshi , was described from the lower Cambrian (Dyeran Series 2, Stage 4) of Parker's Cobble in northwestern Vermont 1884. It represents first fossil exhibiting Burgess Shale-type preservation to have been discovered. The locality presumed worked out and not collected a significant way for more than 100 years. Rediscovery productive layers has...

Floods play a critical role in geomorphic change, but whether peak magnitude, duration, volume, or frequency determines the resulting magnitude of erosion and deposition is question often proposed effectiveness studies. This study investigated that using digital elevation model differencing to compare contrast three hydrologically distinct epochs topographic change spanning 18 years 37-km grave...

The geology, sediment and soil studies are important due to its significant impacts on agriculture, mining, constructions materials, industries, environment, ground water percolation, air pollution, surface pollutions, earthquakes geo-hazards in Afghanistan. In this research, we studied petrography, Sediment, tectonic structures, fraction selection by using hydrometer, sieving analysis, geologi...

The characterisation of particle shape is an important analysis in the field sedimentary geology. At finer scales, it key for understanding sediment transport while at coarser such as boulders, vital coastal protection. However, accurate restricted by application 2D imaging 3D objects or expensive and time-consuming methods X-ray tomography laser scanning. This research outlines a low-cost, eas...
