How the Earth’s crust accommodates magma emplacement influences the signals that can be detected by monitoring volcano seismicity and surface deformation, which are routinely used to forecast volcanic eruptions. However, we lack direct observational links between deformation caused by magma emplacement an...
MINERAL COMPOSITION AND PLATINUM-GROUP ELEMENTS OF THE NEOPROTEROZOIC WANGJIANGSHAN LAYERED INTRUSION AT THE NORTHERN MARGIN OF THE YANGTZE BLOCK: IMPLICATIONS FOR THE PROCESSES OF MAGMA EVOLUTION AND TECTONIC SETTING[J]. Journal of Geomechanics, 2019, 25(2): 267-285. doi: 10.12090/j.issn.1006-...
In addition to factors such as the tectonic setting, magma composition and the bulk gas emission rate of an eruption16, emission rates of volcanogenic metal pollutants depend strongly on element-specific volatility16,17,18 which is a measure of the extent to which an element partitions from the...
XRF analyzers determine the elemental composition of a sample by measuring the fluorescence (or secondary) X-ray emitted from elements in a sample when those are excited by a primary X-ray source. Each of the elements present in a sample produces a set of characteristic X-ray lines (“a fi...
The intracratonic, 2.06 Ga volcanic rocks of the Rooiberg Group of southern Africa consist of nine magma types, varying in composition from basalt to rhyol... J C.,Hatton,and,... - 《Journal of African Earth Sciences》 被引量: 123发表: 1995年 Insight into magma genesis at convergent pl...
Trace element modelling of pelite-derived granites The presence or absence of a vapour phase during incongruent-melt reactions of muscovite and biotite together with the composition of the protolith determines the trace-element characteristics of the resulting melt, provided that equilib...

The last giant impact on Earth is thought to have formed the Moon1. The timing of this event can be determined by dating the different rocks assumed to have crystallized from the lunar magma ocean (LMO). This has led to a wide range of estimates for the
Martian atmospheric40Ar/36Ar composition An appropriate correction factor for the Amazonian Martian atmosphere was determined via isochron analysis of the40Ar/39Ar results. Negligible Marian trapped argon components for most of the nakhlites resulted in little variation in36Ar/40Ar (Supplementary Data1)...
The tungsten isotope constraint is weaker than that for stable isotopes due to the uncertainties in inferring the post-impact composition before the addition of the late veneer (Kruijer et al., 2015; Touboul et al., 2015). Study of lunar samples has revealed that the Moon is significantly ...
