Viscosity measurements of subliquidus magmas: Alkali olivine basalt from the Higashi-Matsuura district, Southwest Japan

We carried out viscosity measurements and sampling of a crystal suspension derived from alkali olivine basalt from the Matsuura district, SW Japan, at subliquidus temperatures from 1230 °C to 1140 °C under 1 atm with NNO oxygen buffered conditions. Viscosity increased from 31 to 1235 Pa s with a decrease in temperature from 1230 to 1140 °C. On cooling, olivine first appeared at 1210 °C, followe...

A Major KREEP-Basalt—Mare Basalt unconformity on the Moon

The lunar regolith records both the geological history and processes of the Moon and also that of particles from the Sun and galaxy. Such a record extends back to the age of the rock unit upon which the regolith is developed, but complex impact gardening and processing makes this record difficult to recover and interpret. Ancient rock units, such as lava flows, begin to have regolith developed ...

Conceptual model for small-volume alkali basalt petrogenesis: implications for volcanic hazards at the proposed Yucca Mountain nuclear waste repository

Today, 31 countries operate ∼ 450 nuclear power reactors supplying electric power to ∼ 1 billion people,∼ 15% of the world population. Nuclear reactors generate∼ 17% of global electric power needs and a number of industrialized countries depend on nuclear power for at least half of their electricity. In addition, ∼ 30 nuclear power reactors are presently under construction worldwide (Macfarlane...

Source and H2O content of high-MgO magmas in island arc settings: An experimental study of a primitive calc-alkaline basalt from St. Vincent, Lesser Antilles arc

Liquidus phase relationships have been determined for a high-MgO basalt (STV301: MgO 12.5 wt%, Ni 250 ppm, Cr 728 ppm) from Black Point, St Vincent (Lesser Antilles arc). Piston-cylinder experiments were conducted between 7.5 and 20 kbar under both hydrous and oxidizing conditions. AuPd capsules were used as containers. Compositions of supraliquidus glasses and mass-balance calculations show th...
