The Ordos Basin

The Ordos Basin: Sedimentological Research for Hydrocarbons Exploration provides an overview of sedimentological approaches used in the lacustrine Ordos Basin (but also applicable in other marine and lacustrine basins) to make hydrocarbon exploration more efficient. Oil exploration is becoming increasingly focused on tight sandstone reservoirs and shales. The development of these reservoirs, particularly regarding the sedimentary processes and the resulting sediments, are still poorly understood. Exploration and exploitation of such reservoirs requires new insights into the lateral and vertical facies changes, and as already indicated above, the knowledge surrounding facies and how they change in deep-water environments is still relatively unclear. Covers several geological aspects so the reader may well understand the context of the various chapters Explores and explains the important relationship between sedimentology and hydrocarbon explorations Highlights the significance of sedimentological aspects (facies, porosity, etc.) for basin analysis and the development of energy resources

Lacustrine Shale Gas: Case Study from the Ordos Basin examines the special sedimentation and formation environment based on the actual exploration of lacustrine shale gas. Using the Chang7 black shale of Yanchang formation in Ordos basin as an example, this book deeply dissects the Lacustrine shale geological characteristics and offers fresh insights into Lacustrine shale geochemistry, shale reservoir, hydrocarbon accumulation and resource evaluation. The book not only enriches, develops and contributes to new theories of shale gas exploration, but also contributes to a new research field, lacustrine shale gas exploration. Shale gas is the mixed phase natural gas that includes adsorbed phase and free phase gas. It is accumulated in the rich organic matter in shale. In recent years, with great changes in global oil and gas exploration and energy supply situation, shale gas has attracted a lot of attention, becoming the focus of the energy industry. Reflects the development of world-leading shale gas exploration technology in China Analyzes first-hand experimental data and scientific research methods on the geological characteristics of lacustrine shale gas Systematically discusses the theory of lacustrine shale gas exploration, from source rock characteristics, shale reservoir characteristics, and shale gas accumulation, to shale gas resources evaluation Provides practical guidance by using the Ordos basin as example

A thought-provoking book on the archaeology of power, knowledge, social memory, and the emergence of classical tradition in early China.

This volume contains papers presented at the 30th International Geological Congress on coal. It includes information on the applications of high-resolution sequence stratigraphy to paralicand terrestrial coal-bearing strata and petrology and depositional environment of Early Jurassic coal.

Fluvial deposits represent the preserved record of one of the major nonmarine environ ments. They accumulate in large and small intermontane valleys, in the broad valleys of trunk rivers, in the wedges of alluvial fans flanking areas of uplift, in the outwash plains fronting melting glaciers, and in coastal plains. The nature of alluvial assemblages - their lithofacies composition, vertical stratigraphic record, and architecture - reflect an inter play of many processes, from the wandering of individual channels across a floodplain, to the long-term effects of uplift and subsidence. Fluvial deposits are a sensitive indicator of tectonic processes, and also carry subtle signatures of the climate at the time of deposition. They are the hosts for many petroleum and mineral deposits. This book is about all these subjects. The first part of the book, following a historical introduction, constructs the strati graphic framework of fluvial deposits, step by step, starting with lithofacies, combining these into architectural elements and other facies associations, and then showing how these, in turn, combine to represent distinctive fluvial styles. Next, the discussion turns to problems of correlation and the building of large-scale stratigraphic frameworks. These basin-scale constructions form the basis for a discussion of causes and processes, including autogenic processes of channel shifting and cyclicity, and the larger questions of allogenic (tectonic, eustatic, and climatic) sedimentary controls and the development of our ideas about nonmarine sequence stratigraphy.

This book is the first contribution to the overview of Precambrian geology of China. It covers Precambrian geology of the North China Craton, the South China Craton and the Tarim Craton, as well as other smaller blocks in the Chinese orogenic belts. It provides systematic concepts of the Chinese paleo-continents and incorporates the most up-to-date achievements. Edited by many of the active researchers working at the forefront of the related fields, it contributes greatly to the international Precambrian geology community and would be of interest to geoscientists working in the research field of geology of China and Precambrian geodynamics.

Carbonate rocks have diverse characteristics. They can be excellent reservoirs as well as prolific source rocks for oil. Oils from carbonate rocks commonly have distinctive bulk chemical and molecular characteristics that reveal their origin. The papers collected here are descriptions and interpretations (that is, case histories) of specific carbonate source rocks that range in age from Precambrian to Miocene.

A strong case can be made that foreland basins are where the casual links between sedimentation and tectonic events were first recognized, as evidenced by the interpretations of geologists working in classic foreland areas. This Special Publication was derived from a Research Symposium entitled "Stratigraphic Sequences in Foreland Basins" held at the AAPG-SEPM joint annual meeting on June, 1992, in Calgary, Alberta, Canada. This volume provides a well-balanced perspective of current research on foreland basin stratigraphy and also serves as another element in the evolving framework that comprises our understanding of foreland basins. Given that so many of earth's resources are found in foreland basins and that foreland basin strata often provide the only preserved record of the tectonic events that led to basin development, the impetus for continued studies of foreland basin strata should remain for many generations of geologists to come.
