This book was released on 2006-01-17 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In January of 2004, twin robotic explorers, Spirit and Opportunity, landed on Mars. Expected to last for 90 days, the two rovers explored the Martian surface for nearly two years. Their objective was to search for evidence of ancient water on Mars, and to determine if Mars ever had conditions that would have been suitable for life. Opportunity, landed on Meridiani Planum, a smooth plateau near the Martian equator, coming to rest in a small impact feature named Eagle Crater. After leaving Eagle Crater, Opportunity drove eastward to Endurance Crater, a much larger carter that allowed access to deeper and older rocks. At these locations, Opportunity, found strong evidence for ancient water on Mars. This evidence includes "blueberries,” small concretions rich in hematite that precipitated from water. Other evidence includes rocks that ware made largely of sulphate salts, deposited when water evaporated, and rocks that preserve ancient ripples that formed billions of years ago as water flowed over sand on Mars. The conditions long ago at Meridiani Planum could have been suitable for some simple forms of life. Whether life could have developed there, however, is a more difficult question.

This book was released on 2014-01-25 with total page 1699 pages. Available in PDF, EPUB and Kindle. Book excerpt: The early development of life, a fundamental question for humankind, requires the presence of a suitable planetary climate. Our understanding of how habitable planets come to be begins with the worlds closest to home. Venus, Earth, and Mars differ only modestly in their mass and distance from the Sun, yet their current climates could scarcely be more divergent. Only Earth has abundant liquid water, Venus has a runaway greenhouse, and evidence for life-supporting conditions on Mars points to a bygone era. In addition, an Earth-like hydrologic cycle has been revealed in a surprising place: Saturn’s cloud-covered satellite Titan has liquid hydrocarbon rain, lakes, and river networks. Deducing the initial conditions for these diverse worlds and unraveling how and why they diverged to their current climates is a challenge at the forefront of planetary science. Through the contributions of more than sixty leading experts in the field, Comparative Climatology of Terrestrial Planets sets forth the foundations for this emerging new science and brings the reader to the forefront of our current understanding of atmospheric formation and climate evolution. Particular emphasis is given to surface-atmosphere interactions, evolving stellar flux, mantle processes, photochemistry, and interactions with the interplanetary environment, all of which influence the climatology of terrestrial planets. From this cornerstone, both current professionals and most especially new students are brought to the threshold, enabling the next generation of new advances in our own solar system and beyond.

This book was released on 2018-12-03 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: High temperature gas-solid reactions are ubiquitous on planetary bodies, distributing chemical elements over a range of geologic settings and temperatures. This volume reviews the critical role gas-solid reactions play in early solar system formation, volcanism, metamorphism and industrial processes. The field evidence, experimental and theoretical approaches for examining gas-solid reaction are presented, building on advances in fields outside of Earth Sciences. Computational chemistry techniques are used to probe the nature of molecular clusters and solvation in volcanic vapors and mineral-gas reaction mechanisms. Specialised analytical methods for characterising solid reaction products are included since these reactions commonly form thin or dispersed films and metastable minerals. Finally, the volume contains rich field examples, laboratory experiments and thermodynamic modelling and kinetics of gas-solid reactions on Earth, Venus and beyond.

Download or read book Amorphous Weathering Products written by Rebecca Smith and published by . This book was released on 2016 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amorphous phases are detected over large regions of the Martian surface from orbit and in more localized deposits by rovers on the surface. Amorphous silicates can be primary or secondary in origin, both having formed through very different processes, so the unambiguous identification of these phases is important for understanding the geologic history of Mars. Secondary amorphous silicates are poorly understood and underrepresented in spectral libraries because they lack the long-range structural order that makes their crystalline counterparts identifiable in most analytical techniques. Fortunately, even amorphous materials have some degree of short-range order so that distinctions can be made with careful characterization. Two sets of laboratory experiments were used to produce and characterize amorphous weathering products under probable conditions for the Martian surface, and one global spectral analysis using thermal-infrared (TIR) data from the Thermal Emission Spectrometer (TES) instrument was used to constrain variations in amorphous silicates across the Martian surface. The first set of experiments altered crystalline and glassy basalt samples in an open system under strong (pH 1) and moderate (pH 3) acidic conditions. The second set of experiments simulated a current-day Martian weathering scenario involving transient liquid water where basalt glass weathering solutions, formed in circumneutral (pH ~5.5 and 7) conditions, were rapidly evaporated, precipitating amorphous silicates. The samples were characterized using visible and near-infrared (VNIR) spectroscopy, TIR spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). All experiments formed amorphous silicate phases that are new to spectral libraries. Moderately acidic alteration experiments produced no visible or spectral evidence of alteration products, whereas exposure of basalt glass to strongly acidic fluids produced silica-rich alteration layers that are spectrally consistent with VNIR and TIR spectra from the circum-polar region of Mars, indicating this region has undergone acidic weathering. Circum-netural pH basalt weathering solution precipitates are consistent with amorphous materials measured by rovers in soil and rock surface samples in Gale and Gusev Craters, suggesting transient water interactions over the last 3 billion years. Global spectral analyses determine that alteration conditions have varied across the Martian surface, and that alteration has been long lasting.

Download or read book Basalt Weathering Rates on Earth and the Duration of Liquid Water on the Plains of Gusev Crater, Mars written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Where Martian rocks have been exposed to liquid water, chemistry versus depth profiles could elucidate both Martian climate history and potential for life. The persistence of primary minerals in weathered profiles constrains the exposure time to liquid water: on Earth, mineral persistence times range from (almost equal to)10 ka (olivine) to (almost equal to)250 ka (glass) to (almost equal to)1Ma (pyroxene) to (almost equal to)5Ma (plagioclase). Such persistence times suggest mineral persistence minima on Mars. However, Martian solutions may have been more acidic than on Earth. Relative mineral weathering rates observed for basalt in Svalbard (Norway) and Costa Rica demonstrate that laboratory pH trends can be used to estimate exposure to liquid water both qualitatively (mineral absence or presence) and quantitatively (using reactive transport models). Qualitatively, if the Martian solution pH> (almost equal to)2, glass should persist longer than olivine; therefore, persistence of glass may be a pH-indicator. With evidence for the pH of weathering, the reactive transport code CrunchFlow can quantitatively calculate the minimum duration of exposure to liquid water consistent with a chemical profile. For the profile measured on the surface of Humphrey in Gusev Crater, the minimum exposure time is 22 ka. If correct, this estimate is consistent with short-term, episodic alteration accompanied by ongoing surface erosion. More of these depth profiles should be measured to illuminate the weathering history of Mars.

This book was released on 2018-12-17 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 31 of Reviews in Mineralogy reviews current thinking on the fundamental processes that control chemical weathering of silicates, including the physical chemistry of reactions at mineral surfaces, the role of experimental design in isolating and quantifying these reactions, and the complex roles that water chemistry, hydrology, biology, and climate play in weathering of natural systems. The chapters in this volume are arranged to parallel this order of development from theoretical considerations to experimental studies to characterization of natural systems. Secondly, the book is meant to serve as a reference from which researchers can readily retrieve quantitative weathering rate data for specific minerals under detailed experimental controls or for natural weathering conditions. Toward this objective, the authors were encouraged to tabulate available weathering rate data for their specific topics. Finally this volume serves as a forum in which suggestions and speculations concerning the direction of future weathering research are discussed.
