Granite is one of the most important components of the continental crust on our Earth; it thus
has been an enduring studied subject in geology. According to present knowledge, granite …

Magnesium (Mg) has an atomic number of 12 and belongs to the alkaline earth element
(Group II) of the Periodic Table. The pure Mg is a silvery white metal and has a melting point …

The geological implications of granitoid magmas with high Sr/Y and La/Yb are debated
because these signatures can be produced by multiple processes. This study presents …

Adakites are commonly associated with porphyry Cu–Au ore deposits worldwide. Two
groups of early Cretaceous adakites occur widely in central-eastern China but their …

The zinc (Zn) stable isotope system has great potential for tracing planetary formation and
differentiation processes due to its chalcophile, lithophile and moderately volatile character …

Magnesium isotopic compositions of a profile through saprolites developed on a diabase
dike from South Carolina have been measured in order to study the behavior of Mg isotopes …

The causes of some stable isotopic variations in felsic rocks are not well understood. In
particular, the origin of the heavy Fe isotopic compositions (ie, high δ56Fe values, deviation …

We present whole rock Li and Mg isotope analyses of 33 ultramafic xenoliths from the
terrestrial mantle, which we compare with analyses of 30 (mostly chondritic) meteorites. The …

We present a method for precise measurement of Mg isotope ratios for low-Mg rock samples
(where MgO< 1 wt.%) by multi-collector inductively coupled plasma-mass spectrometry (MC …

Origin of low δ 26 Mg basalts is a controversial subject and has been attributed to interaction
of isotopically light carbonatitic melts derived from a subducted oceanic slab with the mantle …
