In order to determine the source and critical areas of wind Erosion, Sistan Plain, IRIFR-E.A method was applied. According to geomorphological investigations, the studied area consists of the following two main units namely: Pediment with 1 type and 8 geomorphological facies, and playa with 2 types of flatland and desert type that includes 9 geomorphological facies. On the basis of sediment, th...
The Infra Krol Formation and overlying Krol Group constitute a thick (< 2 km), carbonate-rich succession of terminal Proterozoic age that crops out in a series of doubly plunging synclines in the Lesser Himalaya of northern India. The rocks include 18 carbonate and siliciclastic facies, which are grouped into eight facies associations: (1) deep subtidal; (2) shallow subtidal; (3) sand shoal; (4...
Triassic and Jurassic carbonates across the Middle East host large amounts of hydrocarbons, but the degree of sedimentary heterogeneity across different scales in carbonates varies significantly. In this study we investigate the regional evolution of a carbonate ramp across the Late Triassic to Early Jurassic on the Musandam Peninsula (UAE and Oman) in a series of wadis, 45 km apart. Lithostrat...
Choi, J. K., Ryu, J. H. and Eom, J., 2011. Integration of spatial variables derived from remotely sensed data for the mapping of the tidal surface sediment distribution. Journal of Coastal Research, SI 64 (Proceedings of the 11th International Coastal Symposium), 1653 – 1657. Szczecin, Poland, ISSN 0749-0208 The sedimentary environments of tidal flats on the west coast of Korea are subjected to...
Taking the fluvial reservoir of Neogene Minghuazhen Formation in Bozhong S oilfield China as an example, a detailed study interlayer was conducted. From perspective sedimentary genesis interlayer, three types are summarized and analyzed, namely, fine grain sediment inter peak channel, suspended post flood abandoned channel sediment. At same time, combined with seismic waveform analysis, distrib...
The goal of this work presented in a two-companion paper is to pave the way for reliably assessing risks damage buildings on shore, induced by detonation large-charge historical ordnance (i.e., countermining) variable shallow water environments. Here, we focus impact marine environment, more specifically unconsolidated sedimentary layer, detonation-induced seismo-acoustic wave propagation. We r...
Ordovician limestone-marl alternations in the Oslo-Asker District have been interpreted as signaling glacio-eustatic lowstands, which would support a prolonged "Early Palaeozoic Icehouse". However, these rhythmites could alternatively reflect differential diagenesis, without sedimentary trigger. Here, we test both hypotheses through one Darriwilian and three Katian sections. Our methodology con...
Stratigraphy and facies analysis in a mining waste domain such as tailings storage facilities (TSFs) is still complex task due to sparsely distributed field data. Geophysical techniques the interpretation of geophysical data terms stratigraphy get relevance for integrating geophysics with other models investigating domains (e.g., hydrogeological-geochemical). In this paper, we introduce convent...
The Epanomi gas field discovery during the 1980s at eastern fringe of Thermaikos Basin in Northern Greece proved existence an active petroleum system area. Seismic and drilling exploration programs area provide data to study Cenozoic clastic sequence Basin. This aims recognize, through core well-log data, wide range facies associations from different depositional environments, which contribute ...
The requirements for the accurate characterization of shoal sediments have increased in view fact that strata are eroded due to uplift and it is difficult calculate real thickness granular shoal. To solve this problem, with shoal-to-strata ratio, type distribution range carbonate rock facies described, sedimentary subsequently presented. Taking P2m2a Eastern Sichuan as an example, following con...
