Zirconium stable isotope fractionation during intra-crustal magmatic differentiation in an active continental arc
Zirconium (Zr) stable isotope variations occur among co-existing Zr-rich accessory phases
as well as at the bulk-rock scale, but the petrologic mechanism (s) responsible for Zr isotope …

176Lu–176Hf geochronology of garnet I: experimental determination of the diffusion kinetics of Lu3+ and Hf4+ in garnet, closure temperatures and …
Abstract The 176 Lu–176 Hf and 147 Sm–143 Nd decay systems are routinely used to
determine garnet (Grt)–whole-rock (WR) ages; however, the 176 Lu–176 Hf age of garnet is …

Ahrensite, γ-Fe2SiO4, a new shock-metamorphic mineral from the Tissint meteorite: Implications for the Tissint shock event on Mars
Abstract Ahrensite (IMA 2013-028), γ-Fe 2 SiO 4, is the natural Fe-analog of the silicate-
spinel ringwoodite (γ-Mg 2 SiO 4). It occurs in the Tissint Martian meteorite, where it forms …

A post-accretionary lull in large impacts on early Mars
WF Bottke, JC Andrews-Hanna - Nature Geoscience, 2017 - nature.com
The early impact bombardment of Mars has been linked to the bombardment history of the
inner Solar System as a whole. However, the timing and number of basin-forming impacts …

Decoupled trace element and isotope compositions recorded in orthopyroxene and clinopyroxene in composite pyroxenite veins from the xiugugabu ophiolite (SW …
Pyroxenite veins and dikes are commonly observed in the mantle section of ophiolites.
Because of their mantle occurrence, these pyroxenites are free from crustal contamination …

Recent crustal foundering in the Northern Volcanic Zone of the Andean arc: Petrological insights from the roots of a modern subduction zone
Periodic loss of the lower lithosphere into the convecting mantle due to gravitational
instability is postulated to be a major mechanism for lithosphere recycling in orogenic zones …

The prevalence of kilometer-scale heterogeneity in the source region of MORB upper mantle
The source regions of mid-ocean ridge basalts (MORB) are heterogeneous, consisting of
chemically and lithologically distinct domains of variable size. Partial melting of such …
