Abstract Neoproterozoic–Cambrian amalgamation of West Gondwana involved the collision several terranes older crust that are now in eastern South America and western Africa. U–Pb (SHRIMP) detrital zircon ages from representative metasedimentary units Ribeira Dom Feliciano belts (South America) Gariep Damara (Africa) provide constraints on possible sediment source areas across probable suture zones. zircons Palaeoproterozoic Archaean. For Belt, a contribution Meso- Neoproterozoic is present,...
Dating of single zircons from low-grade metamorphosed rhyolites in the Rosh Pinah Formation Gariep Belt southwestern Namibia, using Pb evaporation technique, yielded a primary crystallization age . Both stratigraphic position and geochemistry volcanic rocks indicate an early continental rift environment. The new data not only provide for massive Zn-Pb-Cu sulfide mineralization associated with these rocks, but they also set maximum limit Neoproterozoic break-up southern Namibia. This is...
The concept of the 4th industrial revolution is becoming a strategic determinant sustainability, success and competitiveness in modern mining sector. importance digital transformation industry has long been debated, hampered part by conservative nature Much debate focused on choosing suitable techniques that provide acceptable levels ore/waste selectivity, scale implementation, cost reduction metallurgical extraction techniques. purpose this review to give an overview minerals extractive...
New U‐Pb zircon ages and geochemical data for felsic intrusive extrusive rocks from the Richtersveld Igneous Complex (RIC) related in westernmost part of 1.03–1.06‐Ga Namaqua‐Natal metamorphic belt, South Africa, indicate that this complex is not to post‐Namaqua orogenic collapse but product mantle‐derived alkaline magmatism an extensional stress field led breakup a Neoproterozoic supercontinent. The oldest age obtained crystallization granitic syenitic melts $$833\pm 2$$ Ma. Continued...
Thousands of rounded particles fine-grained gold, released from a crossbedded gold specimen the Basal reef placer in Welkom field after acid digestion host quartz arenite, have revealed morphological features and abrasion textures that are characteristic detrital gold. The size range, which is between 0.038 0.473 mm, has lognormal distribution with mean 2.88 phi units (0.136 mm) standard deviation 0.48. This well-sorted sediment. shapes predominantly disclike toroidal forms being most...
