White globules in the Makuyama lava dome, Hakone volcano, central Japan

open access: yesWhite globules in the Makuyama lava dome, Hakone volcano, central Japan
application/pdf White globules of highly silicic composition occur in the alternating bands of dacite and rhyolite making up of the Makuyama lava dome, one of the parasitic volcanoes of the Quaternary Hakone volcanic complex. The white globules show a sharp outline and consist dominantly of fine grained feldspar and tridymite.

Resistivity characterisation of Hakone volcano, Central Japan, by three-dimensional magnetotelluric inversion

open access: yesResistivity characterisation of Hakone volcano, Central Japan, by three-dimensional magnetotelluric inversion
On 29 June 2015, a small phreatic eruption occurred at Hakone volcano, Central Japan, forming several vents in the Owakudani geothermal area on the northern slope of the central cones. Intense earthquake swarm activity and geodetic signals corresponding to the 2015 eruption were also observed within the Hakone caldera.

PETROLOGY OF HAKONE VOLCANO AND THE ADJACENT AREAS, JAPAN

Bulletin of the Geological Society of America, 1950
Rocks of Hakone volcano and adjacent areas cover a wide range from basalt to dacite approximate to soda-rhyolite. They were erupted from various different centers during the period from older Miocene to Recent. Two different rock series are recognized, one characterized by the occurrence of monoclinic-pyroxene (a solid solution series from augite to ...
