Accumulation of magnetite by flotation on bubbles during decompression of silicate magma

Knipping, Jaayke L.; Webster, James D.; Simon, Adam C.; Holtz, François (London : Nature Publishing Group, 2019)

Magnetite (Fe 3 O 4 ) is an iron ore mineral that is globally mined especially for steel production. It is denser (5.15 g/cm 3 ) than Earth’s crust (~2.7 g/cm 3 ) and is expected to accumulate at the bottom of melt-rich ...
Bubble-enhanced basanite–tephrite mixing in the early stages of the Cumbre Vieja 2021 eruption, La Palma, Canary Islands

González-García, Diego; Boulesteix, Thomas; Klügel, Andreas; Holtz, François ([London] : Macmillan Publishers Limited, part of Springer Nature, 2023)

Syneruptive magma mixing is widespread in volcanic eruptions, affecting explosivity and composition of products, but its evidence in basaltic systems is usually cryptic. Here we report direct evidence of mixing between ...
Effects of fluorine on the solubilities of Nb, Ta, Zr and Hf minerals in highly fluxed water-saturated haplogranitic melts

Aseri, Abdullah A.; Linnen, Robert L.; Che, Xu Dong; Thibault, Yves; Holtz, François (Amsterdam [u.a.] : Elsevier, 2014)

The effect of fluorine on the solubilities of Mn-columbite (MnNb2O6), Mn-tantalite (MnTa2O6), zircon (ZrSiO4) and hafnon (HfSiO4) were determined in highly fluxed, water-saturated haplogranitic melts at 800 to 1000°C and ...
Iron isotope and trace metal variations during mantle metasomatism: In situ study on sulfide minerals from peridotite xenoliths from Nógrád-Gömör Volcanic Field (Northern Pannonian Basin)

Patkó, Levente; Ciazela, Jakub; Aradi, László Előd; Liptai, Nóra; Pieterek, Bartosz; Berkesi, Márta; Lazarov, Marina; Kovács, István János; Holtz, François; Szabó, Csaba (Amsterdam [u.a.] : Elsevier Science, 2021)

Sulfides from lherzolite and wehrlite xenoliths from the Nógrád-Gömör Volcanic Field (NGVF), located in the Northern Pannonian Basin, were studied to understand the behavior of chalcophile and siderophile elements during ...
Magmatic-hydrothermal fluid evolution of the tin-polymetallic metallogenic systems from the Weilasituo ore district, Northeast China

Gao, Xu; Zhou, Zhenhua; Breiter, Karel; Mao, Jingwen; Romer, Rolf L.; Cook, Nigel J.; Holtz, François ([London] : Macmillan Publishers Limited, part of Springer Nature, 2024)

The large Weilasituo Sn-polymetallic deposit is a recent exploration discovery in the southern Great Xing’an Range, northeast China. The ore cluster area shows horizontal mineralization zoning, from the inner granite body ...
Mixing between chemically variable primitive basalts creates and modifies crystal cargoes

Neave, David A.; Beckmann, Philipp; Behrens, Harald; Holtz, François ([London] : Nature Publishing Group UK, 2021)

Basaltic crystal cargoes often preserve records of mantle-derived chemical variability that have been erased from their carrier liquids by magma mixing. However, the consequences of mixing between similarly primitive but ...
A snapshot of the transition from monogenetic volcanoes to composite volcanoes: Case study on the Wulanhada Volcanic Field (northern China)

Luo, Diao; Reichow, Marc K.; Hou, Tong; Santosh, M.; Zhang, Zhaochong; Wang, Meng; Qin, Jingyi; Yang, Daoming; Pan, Ronghao; Wang, Xudong; Holtz, François; Botcharnikov, Roman (Göttingen : Copernicus Publications, 2022)

The transition processes from monogenetic volcanoes to composite volcanoes are poorly understood. The Late Pleistocene to Holocene intraplate monogenetic Wulanhada Volcanic Field (WVF) in northern China provides a snapshot ...
