In China, numerous shallow mined-out areas have been left due to the disordered mining by the private coal mines. It is of important theoretical and practical value for the roof stability evaluation and disaster forecasting to research the deformation rupture, instability mechanism, and failure mode of the rock roof in the minedout areas.
Stromatolites are the most intriguing geobiological structures of the entire history of the earth since the early beginning of the fossil record in the Archaean. Traditionally, stromatolites and related microbial sediments are interpreted as biosedimentological remains of biofilms and microbial mats. Stromatolites are important environmental and evolutionary archives that give us plenty of information about ancient habitats, biodiversity, evolution of complex benthic biosystems, and generally of Global Change. However, many aspects of the formation, biology, and geobiology of these structures are still cryptic and poorly understood. <...>
Drilling is a process of penetrating solid objects by creating holes using various tools or approaches. When applying rotation to create a hole, the bit has a circular cross section and the produced bore-hole has a round shape. Alternatively, percussive or hammering drills can create non-round bore-holes. Mechanisms of penetrating objects and formations, i.e., drills, are widely used for many applications including making holes, sampling, exploration, and excavation (Bar-Cohen and Zacny, 2009; Clark, 1987; Hossain and Al-Majed, 2015; Rollins, 2010; Zacny et al., 2008). While the field is quite well established, there are still many challenges including operation at extreme conditions as well as drilling extremely hard materials. Drilling on other extraterrestrial bodies also poses significant challenges resulting from the limited resources that are available and the difficult conditions involved. The earliest successful planetary drilling was performed on the moon in 1970 by the Soviets’ robotic Luna 16 lander (Bar Cohen and Zacny, 2009). In recent years, missions have been increasingly launched to drill on Mars and penetrate the surfaces of other extraterrestrial bodies. <...>
This volume organise presentations given by leading international researchers at a NATO Advanced Research Workshop on the state-of-the-art of geological storage of CO 2. The book is divided into 5 parts. Part 1 provides background by describing how human activities are modifying the atmosphere in industrially-active areas in Siberia. Part 2 outlines the innovative idea of using deep permafrost layers as either impermeable boundaries below which CO2 can be injected or as a cooling source for the formation CO2 clathrates. Part 3 describes recent studies conducted on naturally occurring CO2 reservoirs, sites which have the potential to help us understand the possible long-term evolution of CO2 storage sites. Part 4 outlines various industrial-scale applications of CO2 geological storage and shows it to be technically practical, economically feasible and, to date, very safe. Finally Part 5 gives us a view of the future, showing how energy uses are predicted to change over the next 50 years and how the public must be involved in any future decisions regarding climate change abatement.
This volume contains the lectures presented at the NATO ADVANCED STUDY INSTITUTE that took place at Newark, Delaware, U.S.A., July 14-23, 1985. The objective of this meeting was to present and discuss selected topics associated with transport phenomena in porous media. By their very nature, porous media and phenomena of transport of extensive quantities that take place in them, are very complex. The solid matrix may be rigid, or deformable (elastically, or following some other constitutive relation), the void space may be occupied by one or more fluid phases. Each fluid phase may be composed of more than one component, with the various components capable of interacting among themselves and/or with the solid matrix. The transport process may be isothermal or non-isothermal, with or without phase changes. <...>
Volcanoes are an astonishing manifestation of the activity of planets and their satellites, as observed in active and/or fossil examples on Earth, Mars, Venus, Mercury, the Moon and the Jovian satellite Io. On Earth, volcanoes are one of the most impressive evidence of the same imbalance in energy that is also driving plate tectonics. Active volcanoes have terrified and at the same time fascinated populations and civilizations for thousands of years.

The digital era has caused an outstanding change in the acquisition of information concerning our planet. We are accustomed to an uninterrupted monitoring by means of satellite imagery, measurements of ground deformation in the context of geodynamical studies, seismic and geochemical data acquisition, etc. Continuous data acquisition in Earth sciences, in general, and geophysics, in particular, leads to the accumulation of a huge amount of information. Terabytes and Terabytes of data pile up in digital archives over short times. Often, we are left without a key to these archives, which turn them into “data graves,” containing precious information difficult to unearth. In addition, many geological processes are slow phenomena, the study of which comes along with the need to cover time spans as long as possible. Therefore, the necessity to “unearth” old archives becomes of paramount importance <...>
The geologic story of North America is a fascinating one. It’s also more than 4 billion years long—much more than we could ever hope to cover here. However, if you’re curious about the world around you, enjoy the big-picture perspective, and are interested in some of the processes that are constantly reshaping our planet, here’s a crash course on the basics. It’s a good place to start on your aerial tour of the continent’s most breathtaking landforms.
