About 30 m of massive basaltic lava sheets and pillows belonging to the Deccan Traps are exposed at Borivali in the Sanjay Gandhi National Park, Mumbai (India). These lavas are conformably overlain by ~ 100 m of volcaniclastic deposits exposed in the Kanheri Caves. The pillows are plagioclase-clinopyroxene-phyric, very poorly vesicular, tholeiite b...

The early Cambrian to late Neoproterozoic Kelvin kimberlite pipe is located in the southeast of the Archean Slave Craton in northern Canada, eight km northeast of the Gahcho Kué diamond mine. Kelvin was first discovered in 2000 by De Beers Canada. Subsequent exploration undertaken by Kennady Diamonds Inc. between 2012 and 2016 resulted in the disco...

The Cretaceous Liqhobong kimberlite cluster comprises six known diamondiferous Group 1 kimberlite bodies: the Main Pipe (8.5 ha), the Satellite Pipe (1.6 ha), the Discovery Blow (0.15 ha), the Blow (0.1 ha), the Main Dyke, and the East Dyke. Emplaced along a strike length of about 2.5 km, the kimberlites intruded Jurassic Drakensberg lavas and outc...

The present work concerns two occurrences of Neoproterozoic volcaniclastic metasediments in the Central Eastern Desert (CED) of Egypt namely Alam occurrence and Atalla occurrence. They are mainly composed of bedded successions of feldspathic and feldspathic-lithic metagreywackes, arkosic metagreywackes, metasiltstones, and subordinate metaconglomer...

Geothermal Energy
The Taupo Volcanic Zone (TVZ) hosts 23 geothermal fields, seven of which are currently utilised for power generation. Ngatamariki geothermal field (NGF) is one of the latest geothermal power generation developments in New Zealand (commissioned in 2013), located approximately 15 km north of Taupo. Samples of reservoir rocks were taken from the Tahor...

The late Miocene beds of the Puerto Madryn Formation (Provincia del Chubut, Argentina) are formed by shallow marine and estuarine sediments. The latter include several tidal-channel infills well exposed on the cliffy coast of the Peninsula Valdés. The Bahía Punta Fósil and Cerro Olazábal paleochannels are end members of these tidal channels and sho...

Recent marine geophysical surveys reveal the existence of well-developed volcaniclastic deep-sea fans around La Réunion Island, Indian Ocean. The Mafate turbidite complex, located in the northwestern part of the island, is a large sedimentary system formed by two coalescent-like volcaniclastic deep-sea fans: the Mafate fan and the Saint-Denis fan. ...

Detailed examination of volcaniclastic and sedimentary rocks collected from the Taney (30 Ma), President Jackson (4 Ma), Vance (3 Ma) and Alarcon (2 Ma) near-ridge seamount chains of the North Pacific reveals seven clastic lithofacies that record various modes of eruption, magma fragmentation, and particle dispersal. Lithofacies are distinguished b...

Geology of Ore Deposits
The structure of magnetite lodes is determined by iron and sulfur distribution, as well as texture and structure of ore. These features have been revealed by documentation of cores from ore intervals in exploration boreholes penetrating two main lodes 21 and 22 of the Estyunino iron deposit. The documentation of cores was accompanied by sampling fo...

Bien que les systèmes turbiditiques soient très étudiés à travers le monde, les éventails sous-marins volcanoclastiques sont relativement peu connus en comparaison avec les systèmes silicoclastiques. Les nombreuses études réalisées au large des îles d’Hawaii et des Canaries n’ont pas permis d’observer de systèmes turbiditiques bien développé. Des d...
