Written expressly for undergraduate and graduate geologists, this book focuses on how geochemical principles can be used to solve practical problems. The attention to problem-solving reflects the authors'belief that showing how theory is useful in solving real-life problems is vital for learning. The book gives students a thorough grasp of the basic principles of the subject, balancing the traditional equilibrium perspective and the kinetic viewpoint. The first half of the book considers processes in which temperature and pressure are nearly constant. After introductions to the laws of thermodynamics, to fundamental equations for flow and diffusion, and to solution chemistry, these principles are used to investigate diagenesis, weathering, and natural waters. The second half of the book applies thermodynamics and kinetics to systems undergoing changes in temperature and pressure during magmatism and metamorphism. This revised edition incorporates new geochemical discoveries as examples of processes and pathways, with new chapters on mineral structure and bonding and on organic matter and biomarkers. Each chapter has worked problems, and the authors assume that the student has had a year of college-level chemistry and a year of calculus. Praise for the first edition "A truly modern geochemistry book.... Very well written and quite enjoyable to read.... An excellent basic text for graduate level instruction in geochemistry." --Journal of Geological Education "An up-to-date, broadly conceived introduction to geochemistry.... Given the recent flowering of geochemistry as an interdisciplinary science, and given the extent to which it now draws upon the fundamentals of thermodynamics and kinetics to understand earth and planetary processes, this timely and rigorous [book] is welcome indeed." --Geochimica et Cosmochimica Acta
Did you ever hear the name of a place and wonder "where in the world was that?" Answering that question about quaint and historic places in Clark County, Kentucky, became the basis of a regular column in the Winchester Sun called "Where In The World?" The series began on January 6, 2005, with "Bramblett's Lick." This is the third published volume of those collected columns. Previous volumes contained 162 articles published between 2005 and 2016. This volume continues the series with 56 articles that appeared in the Sun from June 2016 to March 2018. There are fewer articles in this volume because more recent articles are much longer than the early ones. Each article describes a historic location or notable person in Clark County, some well known, some not so well known. Some articles were updated from the newspaper version as additional information became available.
Available for the first time as an Omnibus Ebook edition, this three-volume set is the acclaimed full account of the three days at Gettysburg, by the noted historian Harry Pfanz. First Day: For good reason, the second and third days of the Battle of Gettysburg have received the lion's share of attention from historians. With this book, however, the critical first day's fighting finally receives its due. After sketching the background of the Gettysburg campaign and recounting the events immediately preceding the battle, Harry Pfanz offers a detailed tactical description of events of the first day. He describes the engagements in McPherson Woods, at the Railroad Cuts, on Oak Ridge, on Seminary Ridge, and at Blocher's Knoll, as well as the retreat of Union forces through Gettysburg and the Federal rally on Cemetery Hill. Throughout, he draws on deep research in published and archival sources to challenge many long-held assumptions about the battle. Second Day: Gettysburg--The Second Day is certain to become a Civil War classic. What makes the work so authoritative is Pfanz' mastery of the Gettysburg literature and his unparalleled knowledge of the ground on which the fighting occurred. His sources include the Official Records, regimental histories and personal reminiscences from soldiers North and South, personal papers and diaries, newspaper files, and last -- but assuredly not least -- the Gettysburg battlefield. Pfanz's career in the National Park Service included a ten-year assignment as a park historian at Gettysburg. Without doubt, he knows the terrain of the battle as well as he knows the battle itself. Culp's Hill: Harry Pfanz provides the first definitive account of the fighting between the Army of the Potomac and Robert E. Lee's Army of Northern Virginia at Cemetery Hill and Culp's Hill--two of the most critical engagements fought at Gettysburg on 2 and 3 July 1863. Pfanz provides detailed tactical accounts of each stage of the contest and explores the interactions between--and decisions made by--generals on both sides. In particular, he illuminates Confederate lieutenant general Richard S. Ewell's controversial decision not to attack Cemetery Hill after the initial southern victory on 1 July. Pfanz also explores other salient features of the fighting, including the Confederate occupation of the town of Gettysburg, the skirmishing in the south end of town and in front of the hills, the use of breastworks on Culp's Hill, and the small but decisive fight between Union cavalry and the Stonewall Brigade.
In this companion to his celebrated earlier book, Gettysburg--The Second Day, Harry Pfanz provides the first definitive account of the fighting between the Army of the Potomac and Robert E. Lee's Army of Northern Virginia at Cemetery Hill and Culp
