The Changing Role of Geological Surveys


Book Description

Senior managers and Heads of Geological Survey Organizations (GSOs) from around the world have contributed a collection of papers to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs continue to provide key scientific information about Earth systems, natural hazards and climate change. As countries adopt sustainable development principles and the public increasingly turns to social media to find information about resource and environmental issues, the generation and communication of Earth science knowledge become increasingly important. This volume provides a snapshot of how GSOs are adapting their activities to this changing world. The different national perspectives presented converge around several common themes related to resources, environment and big data. Climate change and the UN’s Sustainable Development Goals provide an increased incentive for GSOs of the world to work in harmony, to generate knowledge of Earth systems and to provide solutions for sustainable management of the planet.













Soils of Malaysia


Book Description

There are approximately 500 different soil varieties in Malaysia, most is residual soil and coastal alluvial soil. This book presents a comprehensive overview of various aspects of soils in Malaysia. It covers topics including climate; flora and fauna; geology and hydrology; land use changes for agriculture; soil fertility; human-induced soil degradation; and soil contamination sources. It features information on the role of biological, chemical, mechanical, and physical factors in relation to soil properties. The book highlights land use impact, soil problems arising from contamination and its control methods, the management of problem soils, limiting materials as well as future soil issues. The presentation of different soils in Malaysia is organized through chapters based on two major soil groups (a) the sedentary soils formed in the interior on a wide range of rock types, and (b) the soils of the coastal alluvial plains. The book features information on how these various soil types affect the economy of the country and highlights the soil issues and challenges within the context of sustainable agriculture. Useful to graduate students of soil science, professionals, and agriculturalists, it provides extensive knowledge of agriculture soils in Malaysia in a concise and user-friendly manner.










Geology of North-West Borneo


Book Description

The book is a comprehensive compilation of all aspects of the geology of Northwest Borneo (Sarawak, Brunei and Sabah) and the contiguous South China and Sulu Seas. The sedimentary formations are described, their palaeontology tabulated and ages discussed. Stratigraphic charts illustrate their relationships across the whole region. Detailed geological maps of selected areas are accompanied by cross sections based on outcrop patterns and drilling and seismic data offshore. Palaeocurrent maps are presented and the palaeogeography for different ages described and sedimentary provenance discussed. Descriptions of the ophiolite sequences, volcanic and plutonic rocks are accompanied by tables of selected chemical analyses and geochemical plots and their tectonic significance discussed. All radiometric data are tabulated and discussed. Regional structures and the predominantly Tertiary tectonics are described. In Sarawak the mountains are constructed of Upper Cretaceous to Lower Eocene greenschist facies shaly turbiditic Rajang Group, uplifted before the end of the Eocene. In Sabah the Western Cordillera is constructed of Eocene to Lower Miocene sandy turbidite uplifted in the Late Miocene and Pliocene. Miocene intrusion of Mount Kinabalu and uplift of the Cordillera is related to collision at the Northwest Borneo Trough. Gold, antimony, mercury and copper deposits are described and the tectonic setting of oil and gas deposits discussed.* Correlation tables, descriptions and ages of all major sedimentary formations of Sarawak, Brunei and Sabah* Petrology, geochemistry and ages of all volcanic and plutonic formations of North West Borneo and their tectonic significance* Economic geology including the geological setting of offshore oil and gas deposits




Geology of Peninsular Malaysia

The Physical Geography of Southeast Asia


Book Description

The Physical Geography of Southeast Asia examines the complex mosaic of physical environments which comprise Southeast Asia, and the current environmental problems and management practices which have arisen in this part of the world. The book is in three sections. The first section introduces the basic environmental components (geology, landforms, rivers, vegetation, and others) across the entire region. The second section discusses specific environments that are characteristic of this assemblage of continental and maritime landscapes (volcanic islands, coastal environment, granitic terrains, karst, etc.). The third and final section illustrates the ecological relationship between the environment and people (volcanic hazards, urban environment, coastal zone development, coral reefs, and others). The physical environment of Southeast Asia is examined at different levels, covering a world region that ranges from ancient, stable landmasses to dynamic, unstable plate boundaries, from aged, primary rainforests to brash, vibrant, resource-demanding built environments. Southeast Asia has been perceived as a laboratory for studying plate tectonics. It is an assemblage of large river basins, peninsulas and archipelagos, and seas surrounded by islands. It is an area of great physical variations where parts of the physical environment have been significantly degraded anthropogenically, following rapid population growth and development. In large parts of the region, the forms and processes on land and offshore should no longer be seen as entirely natural. As this book repeatedly illustrates, plate tectonics and people are both important contributors to the physical geography of Southeast Asia. The contributors to this volume are distinguished, scholarly, and have a long association with Southeast Asia. The chapters are not only skilfully built on state-of-the-art research findings but also include new material from the on-going research activities of the authors. The book goes beyond being the first comprehensive and detailed volume of the biophysical geography of Southeast Asia in that it also deals with the tropical environment and the relationship between environment and people in a rapidly developing world region.
