The oils are from two oil fields Kirkuk oil field (K-252, K-265, K-215, and K-392) and Jambur oil field (Ja-15). Bulk geochemical data involve C/N/S-elemental data and Rock-Eval pyrolysis analyses. Following extraction and MPLC fractionation, the aliphatic and aromatic hydrocarbon fractions were investigated by GC/MS. The Rock-Eval pyrolysis results, which carried out on the selected samples, gave different types of kerogen and different maturity stages. As a whole, the Chia Gara Formation from all wells has type II and III kerogens in mature stage in wells K-109 and Tk-3 totally, but in well Bj-1 it is partially mature and in well Hr-1 only the upper part is in early stage maturity. High levels and similar distribution patterns of organic sulfur compounds in Chia Gara source rock bitumens and reservoired oils most clearly document the genetic relationship. Aliphatic and aromatic biomarkers support an origin of Cretaceous reservoired oils from the Chia Gara Formation. ····· 1036188813

Stress inversion of the fault-slip data was performed using an improved Right-Dieder method, followed by rotational optimisation. Seven palaeostress tensor groups (stages) have been identified, ranging from the Late Neoproterozoic to the Holocene period, and have been correlated with the tectonic evolution of the Dead Sea Rift. The results show that new palaeostress data evidence a general clockwise rotation with time of the SHmax axis from an E-W trend in the Cretaceous, to a N-S trend in the Pleistocene. The data also show the appearance of E-W extension in the Late Pleistocene, superimposed on the Dead Sea Stress Field. It therefore suggests that the Dead Sea Rift system formed in a combination of strike-slip and dip-slip movements. Remote sensing methods were extensively used for structural and geological investigations. The classification can only provide indicators for discriminating lithologies on the image, but is certainly not accurate enough for direct geological mapping. ····· 1036188638

This makes the Scandinavian Caledonides a mountain chain where processes taking place in the middle and lower crust during the orogenic cycle can be determined through careful research. Tectonically emplaced peridotite lenses in continental crust are volumetrically minor. However, these lenses can place important constraints on the dynamics in the mantle wedge of the overriding plate during the collision between two terranes. The Friningen garnet peridotite lens is such a lens and is located in the High Pressure Central Belt of the Seve Nappe Complex. With the use of several methods, among which optical- and electron microscopy, bulk rock geochemical analysis and thermobarometry the tectonometamorphic evolution of the Friningen garnet peridotite lens is explained in the context of the Caledonian orogenic cycle. The results of this work show that the Early Caledonian metamorphism of the Seve Nappe Complex is due to a continent-continent collision. ····· 1036188336

Still, the geology of the south-eastern part of the coalfield, developed in the Trans-Damodar Sector was not adequately known owing to very poor outcrop of rocks being almost entirely covered with lateritic or alluvial soil. However, later subsurface study was done, and established occurrence of coal bearing rocks, particularly of Raniganj and Barakar Formation at relatively shallow depth. The outcome of the exploration has proved that the central part of the area is more promising as compared to the northern and southern parts. In the present work, the coal seams developed in the Borjora coal field area in the Trans-Damodar sector have been examined through two studies, namely variation in thickness and variation in ash content which in turn is very important to determine the ultimate usability of coal. The book will also give the preliminary idea for interpreting the basin morphology as well as in establishing the nature of environment of deposition. ····· 1036188214

During September 2001 to August 2002, an extensive program of hydrogeological investigation and laboratory analysis of soil samples were undertaken to achieve the most reliable characterization of the subsoil and eventually to assist in the design and implementation of a pilot artificial recharge system for treated wastewater to groundwater. Regional groundwater flow simulations are made using the three-dimensional numerical model MODFLOW. The groundwater mounding has been simulated with a constant recharge of 60000 m3/d, and an infiltration rate of 0.75 m/d, while all other hydrogeological conditions are assumed as present conditions. The simulation shows that the groundwater mound beneath the center of the recharge basin can be expected to rise to about 15 m above the present water table, and after about 2 years will be a slight increment in the groundwater mound. ····· 1036187860

Ten litho-sections were studied within the outcropping belt of the Gongola Basin, which include: Badabdi, Yayaru Daura, Nguzwa, Chole sections from Dumbulwa Member Dampami, Sabongarin Zambuk and Deba (Borrow Pit) sections from Deban Fulani Member and Dogon Zaga, Gulani and Maliya sections from Gulani Member. Based on facies sequences and associations, shallow marine, estuarine and braided river systems were identified as the major environments of depositions. Clay mineralogical analysis reveals that the Dumbulwa Member mudstones/claystones are dominated by kaolinite with minor illite, while the Gulani and Deban Fulani Members are dominated mainly by kaolinite-montmorillonite and Kaolinite-montmorillonite-illite respectively as the clay mineral assemblages while quartz, feldspars and heamatite are the non-clay minerals associated with the entire sediments.

····· lezzter Preis 38.27€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In this work the possibilities and capabilities of high-resolution crystal plasticity simulations are presented and discussed. Giving several examples, it is shown how the application of crystal plasticity simulations helps to understand the micro-mechanical behaviour of crystalline materials. To avoid the high computational costs associated with crystal plasticity simulations that arise from (i) the evaluation of the selected constitutive law, and (ii) the solution of the associated mechanical boundary value problem, both contributions to the runtime have to be kept small. This is done by (i) employing a rather simple-and therefore fast-constitutive model, and by (ii) using an effective spectral method employing fast Fourier transforms for solving the partial differential equations describing the mechanical behaviour. Here, an improved spectral solver incorporated into the Düsseldorf Advanced Material Simulation Kit (DAMASK) is used. ····· 1036178513

In addition to it, how the tectonics play a vital role in such evolutions. The work area is a hilly region and is a part of Lesser Himalaya and Siwaliks. The two different fault systems (i.e. Main Boundary Fault and Local fault identified in the field) are controlling the erosion and deposition pattern in the area. Sediment budgeting of the study area was done to observe whether the tectonic activity played any role in erosion and deposition of the sediment in the catchment of the Kalagarh River. As the computation of sediment volume at erosional and depositional site will provide quantitative estimation of surface process. The sediment budgeting was done with the help of Digital Elevation Model (DEM) data prepared by using GIS techniques and the work done in the field. Hence the deposition of the sediments observed in the field indicate different depositional environment which helped us to conclude that the topographic response is related to active tectonics in the concerned area. ····· 1036124516

Characteristics vary slightly between samples but generally have I-type signatures. Normalized trends and tectonic comparisons for REE suggest that the granitoid rocks from the area are the crystallization product of an initial partial melting of any combination of volcanic-arc environment and active continental margins. Mineralizations are mostly associated with Cretaceous granites bodies and some are related with younger Miocene intrusive rocks which are mostly occured along the marginal parts of granite plutons. This mineralization displays both of the shallow level to deep level environments. Potential mineralizations have the highest copper grade of 26,500 ppm, zinc 369,000 ppm, lead 216,000 ppm, silver 1,580 ppm, cassiterite 31,200 ppm and manganese 10,100 ppm.

This book focuses on the use of hydrochemistry, multivariate statistics and environmental tracers (18O, 2H, 3H and CFCs) to establish the origin, geochemical evolution, usability and groundwater flow system of groundwater resources of two agro-industrial areas of the CVL (Banana Plain and Mount Cameroon area). The findings of this book are important in that they contribute in the identification of groundwater quality evolution and flow dynamics in these two important agro-industrial areas thereby contributing to the sustainable management of their groundwater resources. Of particular interest is the vulnerability of the shallow aquifers to nitrate contamination to anthropogenic activities in the Banana Plain. In the Mount Cameroon area, the conceptualization of the flow system and the occurrence of different recharge elevations will play a role in finding proper sites for future groundwater development and catchment area protection. ····· 1036120462

This book is an attempt to establish the facies architecture and evaluate the role of tectonics and environment in the evolution of the Boulder Conglomerate Formation, the uppermost unit of the Upper Siwalik Subgroup in the Himalayan Foreland Basin in the Northwest Himalaya. The signatures of post orogenic activities are reflected in palaeocurrent trends, facies variation, texture, provenance and time transgressive nature of the appearance of gravel beds in the study area. The last major tectonic event appears to have resulted in cessation of gravel progradation and quick progression of deformation southwards across the basin increasing the basin slope and modified the drainage system to a situation that more or less prevails till date. ····· 1036119694· 1 ·· 2 ·· 3 ·· 4 ·· 5 ·· 6 ·· 7 ·· 8 ·
