Secondary Plumes Formation Controlled by Interaction of Thermochemical Mantle Plumes With the Mantle Transition Zone

Geophysical Research Letters
The causes and global distribution of intraplate volcanism remain poorly understood, particularly the occurrence of scattered magmatism unrelated to large igneous provinces (LIPs).

Characterization of a Portable Computed Tomography System for In Situ Analysis of Wooden Sculptures in Cultural Heritage

X-Ray Spectrometry, EarlyView.
ABSTRACT Portable X‐ray computed tomography (portable CT) has become an important tool for the non‐destructive investigation of cultural heritage objects, particularly when in situ analysis is required. This work presents the experimental characterization and application of a transportable cone‐beam CT system designed for the inspection of large and ...

Influence of Grain Size Evolution on Mantle Plume and LLSVP Dynamics

Geochemistry, Geophysics, Geosystems
Recent seismic tomography models suggest large‐radius primary plumes originating from the core‐mantle boundary, with grain size variations potentially explaining these observations. Additionally, grain size variations are thought to enhance the long‐term

The company you keep: becoming one(self) in an Indonesian convent En bonne compagnie : devenir (quelqu’)un dans un couvent indonésien Pergaulan dalam biara di Indonesia: sebuah proses pembentukan diri*

Journal of the Royal Anthropological Institute, EarlyView.
This article investigates companionate processes of self‐making in a religious community of Catholic nuns in eastern Indonesia. I argue that the sociality of the convent establishes a unique context for understanding the effects of one's company on processes of self‐becoming.

A seismological study of the mantle beneath Iceland [PDF]

, 2000
Iceland has long been thought to be underlain by a thermal upwelling, or plume, rising from deep within the mantle. This study tests this hypothesis, by a) seeking evidence for a plume in the lower mantle in azimuth anomalies at the NORSAR array and b ...

Putting the Femme in Feminist: Trans Feminism and the ‘Male Lesbian’ in the American Second Wave

Gender &History, EarlyView.
ABSTRACT A slur, a joke or a post‐structuralist case of mistaken identity. To the extent that the male lesbian has been discussed, she has figured dismissively. Yet throughout the period historicised as American feminism's second wave, potentially thousands of trans femmes organised under this identity. Despite being entirely overlooked in scholarship,

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950

Gender &History, EarlyView.
ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Upwellings and Mantle Ponding Zones in the Lower Mantle Transition Zone (660–1000 km)

Geosciences
Convective instabilities at various boundary layers in the earth’s mantle—including the core–mantle boundary, mantle transition zone and lithosphere-asthenosphere boundary— result in upwellings (mantle plumes) and downwellings (subducting slabs).

Research progress of mantle plume

地震科学进展, 2021
Since the mantle plume hypothesis was proposed，it has been controversial in academia，and there is no unified answer to its existence. In this paper，the origin of the mantle plume is elaborated in detail.
