Book Description
Hydrogeochemistry is of great application in reconstructing the previous groundwater circulation under ice sheets due to meltwater recharging the subsurface having a geochemical signature that could be discriminated from the other sources of water produced under warmer climates. Many hydrogeological factors could affect the geochemical composition of groundwater. These include the climate conditions, the lithology of the substrate and its hydraulic conductivity, the weathering, the length of the flow path, the penetration depth, the groundwater flow velocity and the residence time of groundwater.In recent years, hydrogeochemistry advances in analytical technology have allowed hydrogeochemical surveys to become a very powerful exploration technique. The new research works in this area are very broad and extensive. In this mini book, it is impossible to bring all of these novel techniques. The current Advances in Hydrogeochimistry Research book is limited to some diverse examples in different regions of the earth. As an introduction, chemical interaction between surface water and groundwater has been explained and discussed. A hydrogeochemical perspective of the wetland systems is then drawn. It has been combined with the biological remediation. Contaminant fate and transport in both groundwater and soil are also studied using different image analysis techniques. A case study in an Arab region of the world is comprehensively undertaken and the impact of groundwater pollution and quality on regional economics has been investigated. The concepts, classifications and applications of the groundwater modeling for solute transport simulation have been defined in the saturated porous media of the earth. An African analysis was done on assessing the microbiological quality of potable groundwater from the selected protected and unprotected wells in Zimbabwe. 36Cl for dating groundwater was contributed on the Guarani Aquifer System, located beneath the surface of Argentina, Brazil, Paraguay and Uruguay and is the second largest known aquifer system in the world and is attributed as an important source of freshwater. For semi-arid and arid zones of Iran, geospatial techniques in hydrogeochemistry have been used by intersecting the layers and statistical analysis. Then, a hydrochemical analysis of the bottled mineral waters has been comparatively studied. In another part of Africa, a semiarid part of North Eastern Nigeria, physicochemical characteristics of groundwater are widely determined. It has been also shown that the hydraulic fracking associated with the coalbed methane production has a great impact on water resources. Finally, various case studies have been done on the environmental state of freshwater, natural resources and mine waters in the some parts of Serbia, Spain and Central Asia. In addition, the implications on regional water resources management have been indicated.This book is intended primarily as a textbook at the graduate/research level and as a guide for field engineers, enabling them to remain current with scientific developments. As a simple prerequisite, the readers should have basic background knowledge in groundwater engineering and a general understanding of environmental and geological processes.

Book Description
This work summarizes the historical progression of the field of lithium (Li) isotope studies and provides a comprehensive yet succinct overview of the research applications toward which they have been directed. In synthesizing the historical and current research, the volume also suggests prospective future directions of study. Not even a full decade has passed since the publication of a broadly inclusive summary of Li isotope research around the globe (Tomascak, 2004). In this short time, the use of this isotope system in the investigation of geo- and cosmochemical questions has increased dramatically, due, in part, to the advent of new analytical technology at the end of the last millennium. Lithium, as a light element that forms low-charge, moderate-sized ions, manifests a number of chemical properties that make its stable isotope system useful in a wide array of geo- and cosmochemical research fields.

Book Description
Geochemistry concerns the distribution and migration of chemical elements within the Earth, but it comprises much more defined challenges such as the study of the origin of chemical elements, their evolution, the formation of minerals and rocks minerals, and also the role of elements in biology (geobiology). From the beginning, geochemistry has undergone very important advances, especially in the twentieth century which include the study of both the interior and crust of the Earth, the composition of the atmosphere, interaction with living organisms, and the distribution of elements in the Solar System and planets. Modern geochemistry can be applied to nearly all of the Earth Sciences. This book includes chapters discussing the use of geochemistry in environmental geochemistry, the correlation of geological materials, use of rare earths, the study of clays, and the biogeochemistry of petrological applications of geochemistry.

Book Description
Petroleum geochemistry has turned out to be more than another step in the direction to quantify geology and geosciences in general. Petroleum geochemistry as it is today may very well be the triggering event that brings the other branches of geosciences like sedimentology, stratigraphy, structural geology, geophysics and others to a fruitful synthesis as evidenced by integrated basin studies.

Book Description
The second volume of this series consists of three parts. Part I focuses on the research on intracrystalline reactions. This work, which began nearly two decades ago, is critically reviewed by Ghose and Ganguly in Chapter 1. Besides the review, the authors include some of their previously unpublished work to demonstrate how future research could aid in obtaining data on thermodynamics of solid solutions and in understanding the cooling history of igneous and metamorphic rocks. The latter is also the theme adopted by Kretz in the second chapter, which examines the redistribution of Fe and Mg in coexisting silicates during cooling. Chapter 3 contains new data on Fe-Mg distribution in clinopyroxenes. Dal Negro and his co-authors have selected a series of clinopyroxenes from volcanic rocks and present site occupancy data on several clinopyroxenes of intermediate compositions. The data set has not been published before and is the first of its kind. Part II of this book begins with a chapter on melts by Gaskell, who explores the relationship between density and structure of silicate melts. This is followed by the synthesis of data generated in the U.S.S.R. by Shmulovich and his co-authors on fluids. Blencoe, Merkel and Seil present a thorough analysis of the phase equilibrium data on feldspars coexisting with fluids in the third chapter in this part.

Book Description
Advances in Organic Geochemistry 1964 contains papers presented at the Second International Congress on Organic Geochemistry at Rueil-Malmaison, France on September 28-30, 1964. This collection discusses developments made in the field of organic-chemistry and the incorporation of organic matter with clay minerals. To understand the process involved in such association of materials, the text explains the overall reaction between the clay particles and all the organic and inorganic substances in the test solution. The study gives the trace element assemblages found in the Mansfield Marine Band as an example. Another study discusses the occurrence of isoprenoid alkanes in a Precambrian sediment where alkanes and porphyrin pigments, which remain stable for a long time in many geological conditions, can act as biological markers. The paper notes the Marker Bed of the Precambrian Nonesuch Shale Formation in Michigan. The book also presents more research such as those involving the Black Shales of the South-east Sicilian Triassic Basin and the Cretaceous Black Shales of the Cyrenaica Basin. The text then explains the use of electron spin resonance in studying concentrations of free radicals where the results of different measurements made on a Colorado coal are shown on a table. One paper addresses a study of the relative abundance of stable carbon isotopes as pointers to the evolution and genesis of petroleum. This collection will prove valuable for analytical and organic chemists, chemical engineers, geologists, and students of organic chemistry or geology.
