Abs~'act Lower Proterozoic stromatolites and associated clastic carbonate deposits of the Campbell Group, flom the southern margin (Prieska area) of the Kaapvaal Craton, northern Cape Province, are described. Contrary to previous interpretations (Beukes, 1978; 1980a) shallow subtidal to suprafidal facies a r e recognised and discussed in regional context. An alternative model for the facies dev...

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...

Although Deep Learning (DL) architectures have been used as efficient prediction tools in a variety of domains, they frequently do not care about the uncertainty predictions. This may prevent them from being practical applications. In seismic reservoir characterisation, predicting facies data is typically viewed an inverse quantification issue. The goal current study to analyse dependability ro...

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...

Synthetic Aperture Radar (SAR) data can be difficult to interpret over glacierized terrain, especially in areas of high relief where most of the smaller glaciers of the world are found. The two primary objectives of this paper are to correct the topographically induce distortions inherent in SAR image of rugged terrain and to map glacier facies in the corrected polarimetric (PolSAR) image. Meth...

The proposed facies classification approach uses three features of the GLCM with multitemporal X-band SAR data TerraSAR-X combined k-means clustering. This was tested on 15 transboundary Himalayan glaciers. They were classified into six namely debris, dry snow, wet bare ice, percolation zone 1 and 2 covered areas for these classes are 20.56%, 12.50%, 20.26%, 13.16%, 25.49% 8.03% total area resp...

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...
