Snow cover in environmental monitoring is a valuable resource for information on sources of air pollutants and the level pollution. Research areas intense industrial pressure without systematic quality control particular importance this aspect. This case vicinity Łagów (an urban–rural municipality) eastern part Świętokrzyskie Mountains (southern Poland), where rock mining fields have been creat...

The Frasnian carbonate-siliciclastic deposits of the Stipinai Formation exposed in two quarries at Petraši?nai and Klovainiai (northern Lithuania) show considerable vertical facies changes. lower part this succession is dominated by argillaceous dolomitic with subordinate fine siliciclastic deposits. They display haloturbation bioturbation structures, represent a hypersaline lagoonal environmen...

The rock successions of the Chia Gara Formation were studied at two surface sections (Barsarin and Rania) from North-Eastern Iraq. detailed sedimentological study reveals that formation consists basically thin-bedded black limestone, dolomitic marly bituminous shales, Ammonitic limestone. petrography results showed various petrographic components as Ammonites, calcispheres, radiolarian, silicat...

This research aims to distinguish the reef environment from non-reef environment. The Oligocene-Miocene-succussion in western Iraq was selected as a case study, represented by reefal limestone facies of Anah Formation (Late Oligocene) deposited reef-back environments, dolomitic Euphrates (Early Miocene) open sea and gypsiferous marly Fatha (Middle lagoonal content rare earth elements (REEs) (La...

In this paper, we present a detailed analysis of the possibility using unsupervised machine learning techniques for reservoir interpretation based on parameters obtained from geophysical measurements that are related to elastic properties rocks. Four different clustering algorithms were compared, including balanced iterative reducing and hierarchies, Gaussian mixture model, k-means, spectral cl...

a research program was conducted on different clay-bearing rocks selected from the ilam, sarpol-e zahab and tajarak regions (iran) to predict their slaking characteristics. the new durability apparatus (nested mesh drums) separates disintegrated particles varying from > 25.4 to < 2 mm as the drums were rotated. on the basis of the particle size distribution, the disintegration ratio (dr) was us...

Sediment-hosted sulphur deposits provide valuable information on sedimentary biogeochemical processes related to microbial activity and are paleoenvironmental proxy records. They also used as markers for oil exploration the largest ones may represent exploitable economic resources of sulphur. Biogenic occurrences associated with Neogene formations found around Western Mediterranean, in Southern...
