Infos

The Development Potential of Precambrian Mineral Deposits covers several aspects of Precambrian mineral resource potential and assessment towards mineral exploration and mineral reserves. This book contains 27 chapters and begins with an overview of the world production and consumption of certain minerals. The next chapters describe the physical and chemical characteristics of certain mineral ores, as well as the mineral content of certain rock assemblages. These topics are followed by discussions of the geographical distribution of some ores, including discovered metal bearing zones in Africa. Considerable chapters are devoted to exploration techniques in tropical, temperate, and sub-arctic Precambrian areas. The remaining chapters examine the action of metamorphic and other geological processes in mobilizing ore minerals. The book will prove useful to geologists, researchers, and geology students.

Dr. Sam Stuart is a physiotherapist and a research Fellow within the Balance Disorders Laboratory, OHSU. His work focuses on vision, cognition and gait in neurological disorders, examining how technology-based interventions influence these factors. He has published extensively in world leading clinical and engineering journals focusing on a broad range of activities such as real-world data analytics, algorithm development for wearable technology and provided expert opinion on technology for concussion assessment for robust player management. He is currently a guest editor for special issues (sports medicine and transcranial direct current stimulation for motor rehabilitation) within Physiological Measurement and Journal of NeuroEngineering and Rehabilitation, respectively.
