applicability of a biogenic silica-based stratigraphic tool has been success- fully tested in three case studies in The Netherlands, Saudi Arabia and Colombia. The developed tool has great potential for enabling cross-correlation between late Paleozoic continental deposits, which so far was a significant problem, and it has been recently extended to mid-Cenozoic deposits of

· Urban runoff is known as an important contributor to diffuse a wide range of pollutants to receiving environments. Hydrocarbons are common contaminants in runoff mainly transported coupled to suspended particles and sediments. The aim of the study was to investigate the distribution and sources of Aliphatics in the sediments of Tehran's runoff

· Storm-wave sediments are considered a potential unconventional resource in the Middle East region,, the early Silurian Qusaiba Member of the Qaliba Formation in Saudi Arabia. Extremely few studies have examined the controls of lithofacies heterogeneity on pore types, sizes, distribution, and connectivity. Therefore, this study intended to illustrate
· Dammam Dome Formation (Eastern Saudi Arabia) consists of carbonate rocks ranging in age from Paleocene to Eocene. The Rus Formation (Early Eocene) comprises almost 56 m of mixed carbonate-evaporite succession and is exposed in the Dammam Dome area. The present study integrates detailed field, outcrop spectral gamma-ray logging, petrographic
Biogenic silica particles (BSPs) have been discovered in sediments of the Permian - Carboniferous Unayzah Formation of Saudi Arabia. The BSPs are extracted from sediments that are generally barren of macro- or microfossils. BSPs have been found in the Basal Khuff Clastics (BKC), and the Unayzah A, B, and C members, that were sampled in six different wells over a
