Book Description
Sedimentary rocks are created by the deposition or accumulation of material, organic particles, or minerals in bodies of water and formed at the Earth’s surface. Sedimentation is the name given to the formation of these rocks. Limestone, dolostone, clay, sandstone, sandstone, and shale are some common sedimentary rocks formed out of the sedimentation and cementation processes that cause these particles, which can be coarse, medium, or fine-grained or stratified according to their conditions of formation. The first section of this book discusses different aspects of sedimentary rocks. Aquifers are vital resources of freshwater in many countries. However, such groundwater resources are limited, scarce, and unevenly distributed over the Earth’s surface. The second section of this book discusses the basaltic aquifer and aquifers in South Africa.

Book Description
"Extending from Colorado, USA, on the north to the state of Chihuahua, Mexico, on the south, the Rio Grande rift divides the Colorado Plateau on the west from the interior of the North American craton on the east. This volume focuses on the Rio Grande rift's upper crustal basins and is organized geographically with study areas progressing from north to south. Nineteen chapters cover a variety of topics, including sedimentation history, rift basin geometries and the influence of older structure on rift basin evolution, faulting and strain transfer within and among basins, relations of magmatism to rift tectonism, and basin hydrogeology"--Provided by publisher.

Book Description
New exploration tools and techniques for a breakthrough paradigm of regional groundwater occurrence Fresh water is undoubtedly our most precious resource aside from the air we breathe, and the only commodity whose cost has steadily risen over time. At the same time, our understanding of the origins, pathways, and recharge mechanisms of the earth's most valuable "economic" mineral-groundwater-remains in the nineteenth century. It is ironic that this scientific anachronism is contributing to a global shortage of available fresh water supplies while oil, gas, and mineral discoveries have proliferated, vastly increasing the world's energy, precious metals, and industrial mineral reserves. Modern Groundwater Exploration details applications and results of proven twenty-first- century technologies and geological concepts adapted from the oil, gas, and mineral exploration industries for evaluating, developing, and managing previously undiscovered, massive, sustainable groundwater resources. Unprecedented in both its scope and authority, this timely book presents: * A new groundwater paradigm, coined Megawatershed, which accurately and comprehensively describes the earth's natural complex groundwater systems * Innovative exploration, drilling, and testing technologies that make major new ground-water sources more locatable and cost-effective to produce than ever before * Actual case studies in which megawatershed methods have identified vast quantities of new water and brought new hope to previously arid and desperately water-short locales * Chapters by former OECD DAC chairman Alexander R. Love, geopolitical analyst Dr. Ewan Anderson, and former director of the Trinidad and Tobago Water Resources Agency Dr. Utam Maharaj on the tremendous global implications of the megawater-shed paradigm. These experts explore the many beneficial applications of megawater-shed development, from macroeconomics to development of small island developing state (SIDS), and from critical environmental issues to water conflict resolution and the potential for a second "green revolution" The world's need for clean, dependable water is more urgent-and addressable-than ever before. Let Modern Groundwater Exploration introduce you to the authors' revolutionary megawatershed paradigm, along with the latest concepts and technologies for accessing vast reservoirs of groundwater-still today's safest, cleanest, and most plentiful water resource.

Book Description
Authoritative, accessible, and updated introduction to sedimentary rocks for undergraduate students Sedimentary Petrology provides readers with a concise account of sedimentary rock composition, mineralogy, texture, structure, diagenesis, and depositional environments. The new edition of this classic text incorporates the many technological and analytical advances of the last decade, revealing exciting details of processes such as microbial precipitation, how microporosity is created within mudrocks, and the chemical composition of foraminifera deposits, which can be a key indicator for changing seawater temperature. This fourth edition offers a comprehensive update and expansion of the previous editions with a new set of illustrations, new references, and further reading. The new co-author Stuart Jones has brought his considerable expertise in clastic sedimentology to the rewritten chapters on sandstones and mudrocks. The addition of color images throughout the text will aid students immensely in their studies and petrographic fieldwork. Sample topics covered in Sedimentary Petrology include: Advances in modeling and programming to simulate depositional-diagenetic conditions and controls which support field-lab descriptions and interpretations Ocean acidification and the demise of coral reefs, and the role of the oceans in carbon capture and storage Sedimentary ironstones and iron-formations, sedimentary phosphate deposits, coal, oil shale and petroleum, and cherts and siliceous sediments Limestones, evaporites, volcaniclastic sediments, sandstones, conglomerates, breccias, and the effects of microplastics on marine organisms Aimed at undergraduates in geology and earth science, Sedimentary Petrology is an excellent teaching and learning resource for introductory courses in sedimentary rocks.

Book Description
This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.

Book Description
Heterogeneity and anisotropy associated with fractured rock aquifers can make predicting fluid flow pathways difficult using traditional hydraulic testing methods alone. Surface-based self-potentials (SP) measured during pumping and hydraulic testing have been shown in this thesis to provide valuable information used to infer water table drawdown, preferential flow paths and hydraulic properties. To provide a basis for investigating the SP approach in fractured rock, conceptual models were first developed for two separate aquifers. Fracture patterns, combined with pump test and geophysical logging data allowed for flow directions to be assessed within a confined fluvial sandstone-shale aquifer underlying the Springdale wellfield in the Carboniferous Moncton Subbasin. In the Ordovician to Silurian Matapédia Basin, fracture characteristics were measured within the folded turbidite sequences underlying the Black Brook Watershed, and combined with hydraulic conductivity estimates derived from packer testing to provide a better understanding of heterogeneity responsible for anisotropic groundwater flow conditions. Both fractured aquifers were subsequently investigated through SP monitoring and numerical modelling. Transient SP signals recorded during pumping in the Springdale wellfield, combined with measurements of the electrokinetic voltage coupling coefficient, allowed spatial and temporal variations in drawdown to be inferred below electrodes positioned around the pumping well. SP-derived drawdown was fitted to the Theis model to obtain transmissivity and storativity estimates at electrode locations. Numerical modelling showed surface SP measurements to be an excellent proxy for hydraulic head at the top of an underlying confined aquifer even in the presence of hydraulic and electrical heterogeneities. SP signals recorded in the Black Brook watershed during a constant head injection test at a depth of 44 m were used to infer azimuthal anisotropy in fluid flow in directions consistent with dominant fracture set orientations. Numerical modelling showed that fracture transmissivity, length, and frequency all contribute to the magnitude and shape of SP anomalies recorded on surface resulting from flow from the highly transmissive fractures into the surrounding rock matrix. Results from the SP monitoring approach, combined with the conceptual aquifer models, demonstrated an inexpensive and non-invasive means of assessing water table drawdown pattern, preferential flow directions, and hydraulic properties estimates without the need for additional wells.
