This book is devoted to different aspects of tectonic researches. New results and interpretations are presented here for diverse tectonic settings. Most of the chapters include up-to-date materials of detailed geological investigations, often combined with geophysical data, which can help understand more clearly the essence of mechanisms of different tectonic processes. Some chapters are devoted to the tectonic evolution of regions (East Antarctica, East Kazakhstan, Mongolo-Okhotsk orogenic belt), and others have dealt with the different aspects of tectonic events: influence of detachment structural deformation on pore structure evolution in shales, evolution of drainage in response to brittle-ductile dynamics and surface processes, soft sediment deformation structures triggered by the modern earthquakes, and post-opening deformation history of the Japan Sea back-arc basin.

The authors have developed models for predicting beach changes applicable to various problems on real coasts. One of them is the contour-line-change model to predict long-term beach changes caused by the imbalance in longshore sand transport, which is a kind of N-line model. Because the calculation of the nearshore current is not needed in this model, and the computational load is small, it has an advantage in the prediction of long-term topographic changes on an extensive coast. However, the handling of boundary conditions becomes difficult when offshore coastal structures are constructed in a complicated manner, and in this regard the so-called 3D model has an advantage. Taking this point into account, the authors developed a morphodynamic model (BG model) by applying the concept of the equilibrium slope and the energetics approach, in which depth changes on 2D horizontal grids are calculated.

Alice Major observes the comedy and the tragedy of this human-dominated moment on Earth. Major's most persistent question-"Where do we fit in the universe?"-is made more urgent by the ecological calamity of human-driven climate change. Her poetry leads us to question human hierarchies, loyalties, and consciousness, and challenges us to find some humility in our overblown sense of our cosmic significance. Now, welcome to the Anthropocene you battered, tilting globe. Still you gleam, a blue pearl on the necklace of the planets. This home. Clouds, oceans, life forms span it from pole to pole, within a peel of air as thin as lace lapped round an apple. Fair and fragile bounded sphere, yet strangely tough- this world that life could never love enough. And yet its loving-care has been entrusted to a feckless species, more invested in the partial, while the total goes unnoticed. - from "Welcome to the Anthropocene"

Volume 38 of Reviews in Mineralogy provides detailed reviews of various aspects of the mineralogy and geochemistry of uranium. We have attempted to produce a volume that incorporates most important aspects of uranium in natural systems, while providing some insight into important applications of uranium mineralogy and geochemistry to environmental problems. The result is a blend of perspectives and themes: historical (Chapter 1), crystal structures (Chapter 2), systematic mineralogy and paragenesis (Chapters 3 and 7), the genesis of uranium ore deposits (Chapters 4 and 6), the geochemical behavior of uranium and other actinides in natural fluids (Chapter 5), environmental aspects of uranium such as microbial effects, groundwater contamination and disposal of nuclear waste (Chapters 8, 9 and 10), and various analytical techniques applied to uranium-bearing phases (Chapters 11-14).This volume was written in preparation for a short course by the same title, sponsored by the Mineralogical Society of America, October 22 and 23, 1999 in Golden, Colorado, prior to MSA's joint annual meeting with the Geological Society of America.

This thesis presents geological, petrological, geochemical, and zircon U–Pb–Lu–Hf isotopic field data for representative Precambrian lithologies in the Western Liaoning-Northeastern Hebei Provinces along the northern margin of the North China Craton (NCC). It describes late Neoarchean (2.64–2.48 Ga) supracrustal metavolcanic rocks and granitoid gneisses; late Paleoproterozoic (1.72–1.68 Ga) Jianping alkaline plutons and Pinggu alkaline volcanic rocks; and newly discovered ~1.23 Ga mafic dykes. The nature of magma sources and genesis of each magmatic episode are investigated, and the Precambrian (~2.6–1.2 Ga) lithospheric mantle evolution and crust-mantle interaction processes are established for the first time –aspects that provide important constraints in our understanding of the Precambrian crustal evolution and geodynamic processes in the region studied.
