Erbil city is constructed in a flat plain with moderate gradient increasing northwards, the dissected by tens of ephemeral wadis. The maximum elevation high lands NE 1062 m (a.s.l.), whereas center 420 (a.s.l.). average from highest part to 2.15%, towards northeast reach 4.79%. mean annual rainfall 365 mm, while monthly about 24.42 mm. site mainly covered alluvial fan sediments. Towards northea...

The mineralogy of S-bearing phases, S-contents, and S-isotopic compositions of sediments and interstitial waters were determined for three cores drilled during Leg 129 in the western Pacific. Pelagic clays, chalks, and radiolarites generally contain 350-1200 ppm S, with essentially all S present as sulfate. Volcanogenic turbidite units contain about 400 ppm S, with about 10%-20% of total sulfur...

Abstract The needle penetration index (NPI) test is a non-destructive that applicable both in the field and laboratory, does not require any special sample preparation. This has been used for estimation of physico-mechanical properties soft rocks. In this study, influence clay content on relation between uniaxial compressive strength (UCS) NPI investigated some clay-bearing tests were carried o...

Changes in land use due to open pit mining operations, indirectly affect the hydrological cycle. Open especially method, greatly subsurface conditions, such as lithology and hydrogeology. The purpose of this study was analyze hydrogeological conditions before on syncline folds Mahakam river. This research is an inductive with analytical approach which includes use, geology, area dominated by pl...

In this study, geochemical and petrographic characteristics of veins from the Permian Boda Claystone Formation (Mecsek Mts., Hungary) are presented. Understanding connection between these properties is vital in reconstruction paleofluid history tectonic evolution potential high-level radioactive waste disposal site. Each observed four vein generations consists several mineral phases has complex...

Abstract Safety assessments in nuclear waste management typically include the analysis of thermo-mechanical (TM)-coupled processes. The TM behavior host rock is, among other aspects, dependent on prevalent geological geometry. This study aims to evaluate impact uncertainties geometry behavior. It is one very first studies aiming bring structural models and numerical simulations together. To ana...

The Subang, Kaliwangu, and Citalang Formation which are important parts of the Bogor Basin have not been studied, especially from palynostratigraphic aspect. Therefore, this study aims to conduct these three formations that well exposed in Cikandung River area, Sumedang Regency, West Java. Method used research is divided into several stages including sampling by spot sampling; preparation palyn...

Observations of summer microthermal temperature variations suggest, next to hydrological factors, a significant influence plant activity on groundwater flow in fractured claystone materials. Variations microtemperature were compared meteorological parameters and electrical potential plants. With an increase surface temperature, relative air humidity decreases tree potential, measured as the dif...
