Cryogenian Glacial Erosion and Tectonics as Agents of Crustal Recycling

open access: yesTerra Nova, EarlyView.
ABSTRACT Zircon preserves evidence of recycling processes that link surface environments to the mantle. Combined δ18O‐εHf in zircon fingerprints magmatic sources and tracks how crustal material is reworked over time. We apply statistical analyses to a global compilation that apparently resolves shifts in zircon U–Pb, δ18O, and Lu‐Hf data spanning the ...

On the similarity of deep structure of the basement and genesis of depressions on the eastern flank of East Antarctic and in Lake Baikal area

open access: yesЗаписки Горного института
The article analyses the results of geophysical studies of rift structures in East Antarctic, direct geological surveying of which is impossible due to a thick ice sheet.

Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

open access: yesTerra Nova, EarlyView.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

3D Quantification of Subsidence During Pyrenean Retro‐Wedge Initiation: Role of Structural and Thermal Inheritance on Hyperextended Margin Inversion (Aquitaine Basin)

open access: yesTerra Nova, EarlyView.
ABSTRACT We present novel 3D subsidence data enabling vertical movements' quantification during the early formation of the Pyrenean retro‐wedge. From Cenomanian to Turonian times, subsidence is relatively low (~26 ± 10 m/Myr), corresponding to a brief 10 Myr thermal re‐equilibration of the European lithosphere following the hyperextended rift episode ...

Evictability—A Relational Comparison: Fears, Manoeuvres and Regimes of Housing Insecurity in Rapidly Urbanising Cities

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract This article develops the concept of ‘evictability’—the potential of eviction—as a lens for relational comparison of housing insecurity in cities undergoing rapid urbanisation. ‘Evictability’ has advantages over ‘displaceability’, we argue, because it does not meld residents' fears of coerced loss of home with presumptions about ruptured
