in this study, the development of structural elements and the relationship between these elements and dikes emplacements investigated by the field surveys and analysis of satellite images of the east dasht-e bayaz fault zone. in this area nnw-sse (t2) and nw-se trending dikes are which follow the fractures of the region. we measured geometric characters of dikes (such as thickness, attitude, di...

Clay minerals from the three principal kinds of zeolitic sediments from the type area for zeolite facies alteration, the Triassic Murihiku Supergroup, Southland, New Zealand, have been studied by TEM. Bentonitic tuff consists largely of smectite and heulandite with minor illite; they occur as replacements of glass shards and are inferred to be direct alteration products of tuff alteration. Both...

Some non-trilobite faunal elements from Marianian strata of eastern Germany ("Gorlitz Fauna" Lusatia) are presented this region for the first time. One these is Burgess type fossil Halkieria Poulsen, 1967. The extremely low frequency halkieriids in Garlitz fauna and, contrast, very large amount chancelloriids same found horizon point to different habitats two coeloscleritophoran groups and supp...

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...
