Unraveling the eruptive history of the Island of Ischia (southern Italy) is problematic due to its burial, caldera collapse, resurgent uplift and erosion. Here, we present new major and trace element glass data for 39–75 ka proximal tephra deposits,...

Morphology and surface features of olivine in kimberlite: implications for ascent processes (2014)
Journal Article

Most kimberlite rocks contain large proportions of ellipsoidal-shaped xenocrystic olivine grains that are derived mainly from disaggregation of peridotite. Here, we describe the shapes, sizes and surfaces of olivine grains recovered from kimberlite l...

The petrophysical and petrographical properties of hyaloclastite deposits: Implications for petroleum exploration (2014)
Journal Article
for petroleum exploration. AAPG Bulletin, 98(3), 449-463. https://doi.org/10.1306/08141313029

Offshore sequences of volcaniclastic rocks (such as hyaloclastite deposits) are poorly understood in terms of their rock properties and their response to compaction and burial. As petroleum exploration targets offshore volcanic rifted margins worldwi...

The 1300 km3 tholeiitic lava flow field of the 14.98 Ma Roza Member of the Columbia River Basalt Province has the best-preserved vent system of any known continental flood basalt. Detailed geological mapping and logging of the exposed pyroclastic roc...
