The possibility of using Icelandic basalt for production of continuous fibres with presently known technology was investigated. One hundred and forty-five samples were taken based on selected field and petrographical criteria and further geochemically analysed. Additional sample discrimination...
Mine planning is directly dependent on the lithological features and the definition of contacts between materials. Geological modelling is a continual duty that is performed using observation data, which includes open faces information. New data must be continuously acquired and more details are...
The direct measurement of gases trapped in sulphide minerals shows that samples from gold-bearing deposits in Britain and Ireland are anomalously rich in methane. Chalcopyrite samples in deposits of Palaeozoic age sited in Neoproterozoic basement (Caledonides greenschist), Munster Basin...
Both Zn–Pb hypogene sulphide and Zn supergene non-sulphide mineralisation types occur in the Mississippi Valley-type deposit of Florida Canyon, located in northern Peru. The geometry and spatial relationship between the two ore types are very complex to interpret, when it comes to mineral...
The Bozymchak Cu-Au skarn deposit is located in the Chatkal – Kurama region, approximately 130 km east from the Almalyk Cu-Au porphyry mine camp. The current paper provides the results from geochemical study and shows that geochemical characteristics of the Bozymchak area granitoids, including...
Orogenic gold deposits are the main source of gold for humanity. These deposits formed from the Archaean to Phanerozoic at crustal depths of more than 4 km. The key parameters accounting for their formation remain under discussion. I review these parameters in light of recent scientific advances...
