Description / Table of Contents: A lake, as a body of water, is in continuous interaction with the rocks and soils in its drainage basin, the atmosphere, and surface and groundwaters. Human industrial and agricultural activities introduce new inputs and processes into lake systems. This volume is a selection of ten contributions dealing with diverse aspects of lake systems, including such subjects as the geological controls of lake basins and their histories, mixing and circulation patterns in lakes, gaseous exchange between the water and atmosphere, and human input to lakes through atmospheric precipitation and surficial runoff. This work was written with a dual goal in mind: to serve as a textbook and to provide professionals with in-depth expositions and discussions of the more important aspects of lake systems.

Description / Table of Contents: Abstract Reservoir quality is studied using a wide range of similar techniques in both sandstones and carbonates. Sandstone and carbonate reservoir quality both benefit from the study of modern analogues and experiments, but modelling approaches are currently quite different for these two types of reservoirs. There are many common controls on sandstone and carbonate reservoir quality, but also distinct differences due primarily to mineralogy. Numerous controversies remain including the question of oil inhibition, the key control on pressure solution and geochemical flux of material to or from reservoirs. This collection of papers contains case-study-based examples of sandstone and carbonate reservoir quality prediction as well as modern analogue, outcrop analogue, modelling and advanced analytical approaches.

Description / Table of Contents: Scandinavia and its Arctic territories of Svalbard and Greenland represent geographical regions with a long history of Mesozoic palaeontology. However, the last few decades have witnessed a surge of new discoveries. Especially famous are the Triassic and Late Jurassic Lagerstätten of East Greenland and Spitsbergen in the Svalbard Archipelago, together with the Late Cretaceous strata of southern Sweden and the UNESCO World Heritage locality at Stevns Klint in Denmark. The latter records one of the most complete terminal Mesozoic rock successions known globally. Collectively, these deposits encompass the spectrum of Mesozoic biotic evolution, including the explosive radiation of marine faunas after the Permian–Triassic extinction, seminal specialization of amniotes for life in the sea, Late Triassic–Jurassic domination of the land by dinosaurs and the Cretaceous development of modern terrestrial floras and marine ecosystems. This volume, authored by leading experts in the field, encapsulates key aspects of the latest research and will provide a benchmark for future investigations into the Scandinavian Mesozoic world.

Description / Table of Contents: Ore deposits form by a variety of natural processes that concentrate elements into a volume that can be economically mined. Their type, character and abundance reflect the environment in which they formed and thus they preserve key evidence for the evolution of magmatic and tectonic processes, the state of the atmosphere and hydrosphere, and the evolution of life over geological time. This volume presents 13 papers on topical subjects in ore deposit research viewed in the context of Earth evolution. These diverse, yet interlinked, papers cover topics including: controls on the temporal and spatial distribution of ore deposits; the sources of fluid, gold and other components of orogenic gold deposits; the degree of oxygenation in the Neoproterozoic ocean; bacterial immobilization of gold in the semi-arid near-surface environment; and mineral resources for the future, including issues of resource estimation, sustainability of supply and the criticality of certain elements to society.
