Mount Meager massif, the northernmost volcano of the Cascade volcanic belt, has been the site of very large (>107 m3) landslides in the Holocene Epoch. We document two complex landslides at Pylon Peak, one of the peaks of the Mount Meager massif, about 7900 14C and 3900 14C years ago (about 8700 and 4400 calendar years ago). Together, the two landslides displaced 6 × 108 m3 of volcanic rock fro...

Terrestrial Subglacial Volcanism: Many terrestrial subglacial volcanic features have been identified in Iceland [1-3], British Columbia, Canada [4], the Tuva Republic, Russia [5], Alaska [6], and Antarctica [7]. These features are though to follow a typical sequence of events although interpretations and details may differ by author and/or location: a single volcanic vent or short fissure opens...

The rocky innards of the Earth locally melt to produce magma, which sometimes erupts as cataclysmic explosions. The energy released by these eruptions is matched only by that of large meteorite impacts. Whether large pools of magma generate huge volcanic eruptions, whose volume and duration can have global consequences for humanity, or solidify slowly within the Earth’s crust to form plutons (b...

The uppermost section of the Hunter Mine group (HMG) (2728 Ma), a bimodal volcanic complex in the Abitibi greenstone belt, contains both oxide and carbonate facies banded iron-formation (BIF). This paper explores the relationship between volcanic activity and the development of the two types of iron-formation. The oxide facies, represented by chert-jasper-magnetite iron-formation is widespread ...

A study of the diagenetic evolution of sandstones from Panyu low-uplift in the Pearl River Mouth Basin was carried out to unravel the controls on shelf margin sandstone reservoir quality. The reservoir rocks, Oligocene volcanic clastic sandstones of the Zhuhai Formation, have a burial depth of 2765 to 3440 m. 70 samples were studied using the granulometric analyses, X-ray diffraction (XRD) anal...

The area of Esfordi-Zarigan in Central Iran is located in Bafq metallogenic province where most the rock units belong to Precambrian, Infracambrian and Cambrian periods. Although the sedimentary and volcanic rocks are widely distributed, this research is mainly focused on petrogenesis of plutonic rocks. From stratigraphic point of view sedimentary and volcanic rocks can be classified in five ma...

Magmatic sheet intrusions (dykes) constitute the main form of magma transport in the Earth's crust. The size distribution of dykes is a crucial parameter that controls volcanic surface deformation and eruption rates and is required to realistically model volcano deformation for eruption forecasting. Here we present statistical analyses of 3,676 dyke thickness measurements from different tectoni...
