Explosive volcanic eruptions constitute a major class of natural hazard with potentially
profound economic and societal consequences. Although such eruptions cannot be …

Mafic alkaline magmas, such as those feeding the persistent eruptive activity of Stromboli
and Mt. Etna volcanoes in Italy, are dominated by the crystallization of plagioclase via …

Before Perseverance, Jezero crater's floor was variably hypothesized to have a lacustrine,
lava, volcanic airfall, or aeolian origin. SuperCam observations in the first 286 Mars days on …

Vesicles in volcanic rocks are frozen records of degassing processes in magmas. For this
reason, their sizes, spatial arrangements, numbers and shapes can be linked to physical …

The lunar basalt samples returned by the Chang'e-5 mission erupted about 2.0 billion years
ago during the late period of the Moon's secular cooling. The conditions of mantle melting in …

Grinding for mineral liberation is a prerequisite for a successful flotation separation. Different
grinding media produce mineral particles with different surface properties and flotability. In …

A fast and effective method has been developed to measure total optical porosity (TOP) of
blue resin-impregnated thin sections. This utilises a macro file (jPOR. txt) for ImageJ, which …

Physical properties of some weathered/altered volcanic rocks and their variation with the
degree of alteration are described in detail. A series of tests was performed to identify and …

Given the prolific work on the petrography and mineral chemistry of volcanic rocks to
understand magmatic processes for well over a century, it is surprising that there are no …

Here, the influence of grinding media with different shapes on the flotation performance of
spodumene and its potential mechanism from microscale insights was investigated using a …
