Vanadium (V) [Z = 23]
Vanadium occurs in nature in a wide variety of minerals. The following four main types of mineral deposits are recognized: vanadiferous... -
Submarine Volcano 8.10 (Kuril Island Arc)
AbstractSubmarine volcano 8.10, which is part of the South Iturup group of submarine volcanoes in the Kuril Island Arc (KIA), was studied using a...

Sulfide minerals and chalcophile elements in The Pleiades Volcanic Field, Antarctica: implications for the distribution of chalcophile metals in continental intraplate alkaline magma systems
Fractionation of sulfides during ascent of mantle-derived magmas distributes sulfur and chalcophile elements into the Earth’s lithosphere. It has...

Titanomagnetite Ore in the Chiney Pluton
There are two Fe-Ti-V deposits in the Chiney pluton—Magnitnyi and Etyrko. They represent the largest deposits of commercially viable vanadium ore in... -
Properties of Thermochemical Remanent Magnetization on Basalt Samples Containing Titanomagnetites with Increased Thermal Stability
Abstract —The experiments have been carried out on the acquisition of thermochemical remanent magnetization (TCRM) in recent Kamchatka basalt...

Ulvöspinel (ulv/ulvite)
This chapter describes Ulvöspinel (abbrv. ulv), as seen with optical, reflected light microscopy. After summing up compositional data, main... -
Paleomagnetism and paleomagnetic dating to large volcanic bombs: an example from the historical eruption of Azuma–Jododaira volcano, NE Japan
Vulcanian activity is one of the most common eruption styles of arc andesitic volcanism on Earth. It ejects and deposits volcanic bombs around the...
