Global data for measured Fe 2 O 3/FeO ratios and Cu contents in unaltered volcanic and
intrusive arc rocks indicate that, on average, they are slightly more oxidized than other …

Metals such as Cu, Mo, Au, Sn, and W in porphyry and related epithermal mineral deposits
are derived predominantly from the associated magmas, via magmatic–hydrothermal fluids …

The Th/U ratios of zircon crystals are routinely used to help understand their growth
mechanism. Despite the wide application of Th/U ratios in understanding the geological …

Abstract Most of the Himalayan Cenozoic leucogranites are products of partial melting of
metapelite sources. In the Malashan-Gyirong area (southern Tibet), the geochemical …

Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

Rutile is the most common naturally occurring titanium dioxide polymorph and is widely
distributed as an accessory mineral in metamorphic rocks ranging from greenschist to …

Three distinct groups of eclogites (low-Mg–Ti eclogites, high-Ti eclogites and Mg-rich
eclogites) and ultramafic rocks from the depth interval of 100–680 m of the Chinese …

Partial melting at continental lithosphere depths plays an important role in generating
geochemical variations in igneous rocks. In particular, dehydration melting of ultrahigh …

Recycling of oceanic crust together with different types of marine sediments has become
somewhat of a paradigm for explaining the chemical and isotopic composition of ocean …

We present new experimental apatite/melt trace element partition coefficients for a large
number of trace elements (Cs, Rb, Ba, La, Ce, Pr, Sm, Gd, Lu, Y, Sr, Zr, Hf, Nb, Ta, U, Pb …
