The characteristics of magma supply, storage, and transport are among the most critical
parameters governing volcanic activity, yet they remain largely unconstrained because all …

Abstract The Pliocene (7 Ma) Nb-enriched arc basalts of the Valovayam Volcanic Field
(VVF) in the northern segment of the Kamchatka arc, Russia, host abundant mantle …

Deciphering the evolution of the internal dynamics of magmatic plumbing systems and
identifying the key parameters that drive such dynamics are major goals of modern …

We have studied 30 quenched tholeiitic lava flows recovered by 20 dredge hauls and one
submersible dive along Puna Ridge, the submarine part of the East Rift Zone of Kilauea …

The south flank of Kilauea Volcano is unstable and has the structure of a huge landslide; it is
one of at least 17 enormous catastrophic landslides shed from the Hawaiian Islands …

The 19 known shield volcanoes of the main Hawaiian Islands—15 now emergent, 3
submerged, and 1 newly born and still submarine—lie at the southeast end of a long-lived …

The isotopic composition of carbon has been determined in a suite of xenoliths from lava of
the 1800–1801 Kaupulehu eruption of Hualalai Volcano, Hawaii. Several lithologies are …

Many modern linear volcanic chains on the Pacific plate can be backtracked to the general
region of large Mesozoic seamount provinces in the far western Pacific, but those provinces …

Hualalai Volcano is unique among Hawaiian volcanoes in that it possesses a relatively high
proportion of evolved, trachytic lavas that were erupted at the beginning of the alkalic …

Ultramafic xenoliths were found in recent alkali basalts from São Tomé Island. These include
spinel peridotites (lherzolites, harzburgites and dunites) and pyroxenites (orthopyroxenites …
