INTRODUCTION Specogna (Babe) gold property consisting of 41 full claims and seven fractions is 17.6 kilometres south of the town of Port Clements on Graham Island (Fig. 48). The showing is a prospecting dijcovery, found in late 1970 by Efrem Specogna and Johnny Trico. Five companies optioned the property iuccessively from 1971 to 1975 during which time geochemical sampling, trenching, and diamo...

We present a first paragenetic study of the Wuyier, Wuyisan, Wuyiyi and Shihongtan sandstone-hosted roll-front uranium deposits, northwest China. The mineralization is hosted by Lower–Middle Jurassic coarseto medium-grained sandstones, which are dark-gray to black due to a mixture of ore minerals and carbonaceous debris. The sandstone is alluvial fan-braided river facies. Minerals associated wi...

Surface coal mining in Appalachia disturbs hundreds of hectares of land every year with the removal of valuable and ecologically diverse eastern deciduous forests. After the passage of the Surface Mining Control and Reclamation Act in 1977, coal mine operators began planting a variety of grasses and legumes as a fast and economical way to reestablish a permanent vegetative cover to meet erosion...

The study of facies analysis and interpretation the depositional environment Lemat Formation located at Bukit Tiga Puluh aims to clarify problems found in Paleogene sediments South Sumatra Basin. A detailed fluvial has been carried out Lubuk Bernai track. number observations, profiling, measured stratigraphic section have out. stratigraphy area can be divided into 5 units from old young, namely...

Surface mining in West Virginia removes the eastern deciduous forest and reclaiming the mined land to a productive forest must consider soil depth, soil physical and chemical properties, soil compaction, ground cover competition, and tree species selection. Our objective was to evaluate tree survival and growth in weathered brown sandstone and in unweathered gray sandstone. Brown and gray sands...

Sandstone type uranium is the most valuable and has potential for mining among known deposits. In process of forming, hydrolytic migration enrichment require special basin sedimentary environment tectonic background. Therefore, mineralization sandstone deposits certain layering characteristics distribution rules in underground vertical depth space. It important to mine spatial uranium-bearing l...

the jajarm karst bauxite deposit is located about 175 km southwest of bojnourd. the deposit has been developed as a stratiform horizon along the contact of triassic dolomites and the jurassic shales and sandstone. in this study, the textural elements of the jajarm bauxites are classified into matrix and separated textures based on morphological and genetic criteria. pelitomorphic and microgranu...

Each year surface mining in Appalachia disrupts large areas of forested land. The Surface Mining Control and Reclamation Act requires coal mine operators to establish a permanent vegetative cover after mining, and current practice emphasizes soil compaction and planting of competitive forage grasses to stabilize the site and control erosion. These practices hinder recolonization of native hardw...
