Book Description
This book describes the nature and origin of the Macraes gold deposit. It also documents the key features of this spectacular deposit for a wide range of professionals in the resource geology community. This world-class gold deposit has been a spectacular geological and economic success story, as it has developed from a small historical gold mine in discontinuous quartz veins measuring only meters to a large-scale mine in deposits spreading over kilometres in extensive disseminated gold-bearing rock.

Book Description
Mine areas left behind by companies that no longer exist are defined as derelict mines – those that were operated and closed at a time when most countries did not have adequate regulations requiring rehabilitation of the impacted mine areas. This book provides unique information on the extent and severity of derelict mines’ impact on environmental degradation and human and environmental health. It examines the nature of derelict mines, short-term and long-term risks to sensitive receptors, tools for monitoring and prioritizing risks, and technological advances for rehabilitation. This book considers a risk-based approach to managing derelict mines, which is reliable and cost-effective. FEATURES Provides fundamental information on derelict mines and their inventory in different countries Explains risk-based management of derelict mines and the importance of community perspectives as a reliable and cost-effective method Identifies ownership and liability issues through many case studies in Australia and other countries that must deal with the remediation of derelict mines Presents remediation, assessment, and predictive tools for managing pit lakes Helps readers set standards, regulatory measures, and policies related to mine closures This book is for engineers and professionals who work in mining, geology, chemistry, mineralogy, geotechnics, and hydrogeology and deal with industrial site management, waste management, mine closures, mine site reclamation, derelict mine remediation, and mine revegetation. It is also an insightful resource for graduate students, academics, and researchers focused on these courses.

Book Description
La province de Pataz au Nord-Pérou est la plus septentrionale des ceintures paléozoïques d'or, antimoine et tungstène orogéniques (mésothermales) de la Cordillère Orientale des Andes Centrales. Longue de plus de 160 km, elle est connue pour ses veines épigénétiques de quartz aurifères riches en sulfures (ressource : 40 millions d'onces d'or). Les minéralisations, datées à ~314 Ma, sont localisées dans des fractures inverse-décrochantes dextres et d'extension le long des marges et à l'intérieur du batholite de Pataz (329 Ma) et dans les roches métasédimentaires avoisinantes. L'intrusion hôte n'exerce qu'un rôle passif dans leur genèse et fonctionne uniquement comme un réceptacle structural très favorable. La minéralisation est temporellement liée à un stade d'exhumation du bâti et à l'addition d'un flux de chaleur dans une croûte épaissie. Le piégeage de l'or au contact des sulfures microfracturées interviendrait à 5-10 km de profondeur par dilution d'un fluide salin précoce par des eaux superficielles.
