This book was released on 1992 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific questions addressed by the Creede Scientific Drilling Project were as follows (Bethke et al., 1992): (1) Did the lacustrine sedimentary sequence filling the moat of Creede caldera serve as reservoir for the moderately-saline aqueous fluids which scavenged and then transported silver and base metals to ore-depositional sites for the rich epithermal deposits of the Creede mining district (Fig. 1)?; (2) what were the chemical and isotopic compositions of these fluids prior to their entry into the Creede fracture (later vein) system; (3) how did these chemical and isotopic compositions evolve in transit to the ore-depositional site?; (4) how did the Creede caldera form and evolve?; (5) what is the present thermal regime in Creede caldera moat? {hor_ellipsis}the, paleothermal regime?; (5) what are the hydrologic transport properties of the moat sedimentary rocks?; (6) what diagenetic or hydrothermal veins disrupt the moat sedimentary sequence, and what do their paragenetic relationships, mineralogic compositions, fluid-inclusion characteristics, and stable-isotope systematics reveal about evolution of the Creede hydrothermal system? Two Creede caldera moat drill holes were completed for this project.

Download or read book Mechanisms of Activity and Unrest at Large Calderas written by Claudia Troise and published by Geological Society of London. This book was released on 2006 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large caldera collapses represent catastrophic natural events, second only to large meteoritic impacts. In addition, some calderas are densely populated, making the risk extreme, even for moderate eruptions. Understanding caldera mechanisms, unrest and the danger of eruption is therefore a crucial challenge for Earth sciences. Several key features of caldera behaviour have yet to be fully understood. Through a combination of case studies and theoretical modelling, the following topics are addressed in this volume: the conditions required to produce and to release large volumes of magma erupted during caldera formation; how magmatic feeding systems evolve before and after a caldera has formed; the processes that limit the behaviour of precursors to eruptions; how pre-eruptive precursors can be distinguished from those that drive unrest without an eruption; and given that post-collapse eruptions may occur across a wide area, the optimum procedures for designing hazard maps and mitigation strategies.

Download or read book Volcanoes written by John P. Lockwood and published by John Wiley & Sons. This book was released on 2013-04-26 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanoes are essential elements in the delicate global balance of elemental forces that govern both the dynamic evolution of the Earth and the nature of Life itself. Without volcanic activity, life as we know it would not exist on our planet. Although beautiful to behold, volcanoes are also potentially destructive, and understanding their nature is critical to prevent major loss of life in the future. Richly illustrated with over 300 original color photographs and diagrams the book is written in an informal manner, with minimum use of jargon, and relies heavily on first-person, eye-witness accounts of eruptive activity at both "red" (effusive) and "grey" (explosive) volcanoes to illustrate the full spectrum of volcanic processes and their products. Decades of teaching in university classrooms and fieldwork on active volcanoes throughout the world have provided the authors with unique experiences that they have distilled into a highly readable textbook of lasting value. Questions for Thought, Study, and Discussion, Suggestions for Further Reading, and a comprehensive list of source references make this work a major resource for further study of volcanology. Volcanoes maintains three core foci: Global perspectives explain volcanoes in terms of their tectonic positions on Earth and their roles in earth history Environmental perspectives describe the essential role of volcanism in the moderation of terrestrial climate and atmosphere Humanitarian perspectives discuss the major influences of volcanoes on human societies. This latter is especially important as resource scarcities and environmental issues loom over our world, and as increasing numbers of people are threatened by volcanic hazards Readership Volcanologists, advanced undergraduate, and graduate students in earth science and related degree courses, and volcano enthusiasts worldwide.

Download or read book Ancient Landscapes of Western North America written by Ronald C. Blakey and published by Springer. This book was released on 2017-10-03 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section
