The north-dipping Hout River Shear Zone (HRSZ), which marks the boundary between high-grade Limpopo Complex in its hanging wall and low-grade granite-greenstone terrane of Kaapvaal Craton South Africa footwall, is a deep-crustal shear zone that controlled emplacement hot granulites over against granite-greenstones during exhumation at ~2.72–2.62 Ga. This major migration large volumes hydrous fl...

Mining waste are materials that result from the exploration, mining and processing of substances can consist natural materials, processed to varying degrees during ore-processing enrichment phases, possibly containing chemical, inorganic organic additives. Evaluation REEs potential Klein Letaba tailings dam was envisaged assist in containment at currently un-rehabilitated mine material. These a...

Using the most comprehensive developing country dataset ever compiled on air and water pollution and environmental regulations, the paper assesses India’s environmental regulations with a difference-in-differences design. The air pollution regulations are associated with substantial improvements in air quality. The most successful air regulation resulted in a modest, but statistically insignifi...

Archaean komatiites of the greenstone belt in Manica area, western Mozambique contains accessory amount of disseminated chromite grains. The komatiite rocks comprise peridotitic and basaltic komtiite. These komatiites are affected by regional metamorphism as all of the studied area. It is observed that only chromian spinel is preserved as the primary mineral and that all the other primary miner...

In recent years, the use of small screen devices has multiplied rapidly. This paper covers a number of different issues which arise when digital libraries are used in combination with such displays. Known limitations of small screens are presented to the Digital Library community. Two evaluations of pilot small-screen DL systems are presented, with some unexpected cultural and socio-technical c...

Archean greenstone belts are renowned for their Au endowment. Gold can be associated with orogenic style of mineralization and diorite-hosted Au-Cu disseminated sulfides interpreted as a porphyry mineralization. The Regnault project, located in the Frotet–Evans belt (Superior craton), is structurally-controlled an unclear metallogenic model. aim this study to evaluate fertility granodiorite-dio...
