The dynamics of tropical weathering through time with the formation and long-term evolution laterite associated climatic geodynamic forcing is still a poorly explored issue. To better access this, we focused on lateritic-bauxitic duricrusts from well-explored, 300 m high Kaw mountain in northeastern French Guiana. Macroscopically homogeneous Fe (oxyhydr)oxides-rich subsamples were separated 10 ...

Researchers conducted research into the strength properties of a Geopolymer produced from eggshell powder, bauxite, and flyash with RGL (Reaction generating liquid) cure for 84 days at ambient temperature. Also studied were changes in products Morphology, XRD, FTIR studies SEM images microstructure. The results indicated that, various mix proportions, gradually improved 28 to days. aged Geopoly...

Ivory Coast is a country rich in base metals and precious minerals: gold, manganese, diamond, iron, bauxite, cobalt nickel. These natural resources are exposed to destruction fragmentation by mining activities. The artisanal small-scale exploitation of gold increasingly practiced our rural areas. activities escape often the control monitoring administration. In order better constrain these on e...

The status and prospects of the mineral resource base solid minerals Bolivarian Republic Venezuela, as well possibilities for developing RussianVenezuelan cooperation in field geology management are considered. Venezuela has world's largest oil reserves a wide range (gold, diamonds, nickel, bauxite, iron ores, tantalum niobium, other rare metals, various industrial minerals), which retains sign...
