Basalt and alkaline volcanic rocks intruded the Dnieper-Donets rift zone during this time and the Dnieper-Donets Depression and Donets Basin formed. The Lvov-Volyn Depression developed in the Volyn-Podolia Platform during the Devonian and Carboniferous.įurther tectonic changes came about with the Hercynian orogeny, beginning the formation of the Prichernomorian Depression. Ukraine experienced volcanic activity related to the Caledonian orogeny. In the Paleozoic, the Volyn-Podolia region and southern Ukraine subsided and were flooded by a marine transgression, which immersed the region until the Devonian (or until the Permian further south). During the Riphean period, a delineation of Eastern European stratigraphy, the Dnieper-Donets Rift began to form. The evolution of the rock units in the Proterozoic produced the stable Ukrainian Shield, which was broken up further into horst and graben formations by the Baikalian orogeny. Tectonic forces had fractured the Archean basement rock into sutures, blocks, troughs and depressions by the start of the Proterozoic, although new folding began. Proterozoic (1.5 billion-539 million years ago) The Late Archean was marked by the deposition of ancient greywacke, charnockite and basic eruptions from numerous volcanoes and fumaroles. These rocks, including plagioclase granite, basalt and gneiss, was reworked into granulite belts due to tectonic evolution in the Archean. In the Early Archean, the oldest granite layer that now form the Precambrian crystalline basement rock of Ukraine began to form. Stratigraphy, tectonics & geologic history The country has numerous metal deposits as well as minerals, building stone and high-quality industrial sands. Ukraine was impacted by the Pleistocene glaciations within the last several hundred thousand years. Ukraine was intermittently flooded as the crust downwarped during much of the Paleozoic, Mesozoic and early Cenozoic, before the formation of the Alps and Carpathian Mountains defined much of its current topography and tectonics. Extensive tectonic evolution and numerous orogeny mountain-building events fractured the crust into numerous block, horsts, grabens and depressions. The oldest rocks in the region are part of the Ukrainian Shield and formed more than 2.5 billion years ago in the Archean eon of the Precambrian. Tuesday on " CBS This Morning" we will show you more of the story of Ziki, the young boy we found at the mines, and some of the efforts being taken to rescue the children.The geology of Ukraine is the regional study of rocks, minerals, tectonics, natural resources and groundwater in Ukraine. The charity described the support from these multinational companies as a "drop in the ocean," as countless companies are buying the child mined cobalt. We spoke to Pact, an NGO that is working with Apple, Microsoft and Huayou. One man told us that the Chinese traders at the market bought all the cobalt and sold it mainly to one Chinese company, Congo Dongfang Mining, known locally as CDM.ĬDM is owned by global Chinese giant Huayou, which said they stopped buying from that market last year and have put in place a detailed program to eliminate child labor from their supply chain.īut in this murky process of sourcing cobalt, one thing is clear children are still here, carrying the weight of our high-tech world on their shoulders.ĬBS News spoke with eight major electronic and vehicle companies who have been connected to this supply chain, and though many have joined initiatives to solve this problem, at the mines Patta visited our team saw little evidence of anyone on the ground helping these children. When we offered to sell a truck load of cobalt, nobody asked us who mined the mineral, only what the quality was. CBS News wanted to see whether there was any attempt to check at the market whether the cobalt had been mined by children, so Patta's team went back later, with a hidden camera. The children's cobalt is brought to a large market where it is bought by a Chinese company for extremely low prices. Sacks were already mixed up - without labels - making it impossible to know who had mined the mineral inside. We followed the mineral as it left the mines - piled high on every mode of transport available, including bicycles. More company responses:īut our investigation shows just how complicated it is to trace child-mined cobalt in the global supply chain. Samsung said it's mapping its supply chain, and Tesla explained it performs audits, and has very little cobalt in its batteries. Microsoft told us it does not tolerate child labor and that it is working with NGOs to eliminate it. Mineral's obscurity poses problems for tech companies 02:27Īpple said it leads the industry in supply chain standards, and last year cut ties with the largest artisanal cobalt supplier.
