Base metal mineralisation associated with Ordovician shales in south-west Scotland [PDF]
, 1984 Several narrow, lenticular belts of black cherty mudstone and siltstone (the Moffat Shales), alternating with thick greywacke sequences, strike north-east to south-west across Galloway with uniformly steep dip.

On the sphalerite geobarometer.
GEOCHEMICAL JOURNAL, 1988 Even though the sphalerite geobarometer enjoys wide support as a very reliable parameter which gives pressure values consistent with the pressures obtained by different silicates equilibrium, thermodynamically the internal consistency of its experimental data may be questioned. The pressure read from the geobarometer should be regarded tentatively.

Lithium Isotopic Analysis of Spodumene by Secondary Ion Mass Spectrometry
Rapid Communications in Mass Spectrometry, Volume 40, Issue 13, 15 July 2026.ABSTRACT Rationale Lithium (Li) stable isotopes can provide insight into fluid–rock interaction and magmatic differentiation. Therefore, it is essential to develop an accurate and precise method to determine the Li isotope signature in spodumene.

Three-dimensionally confined diluted magnetic semiconductor clusters. Zn1−xMnxS [PDF]
, 1991 We report the first example of a dilute magnetic semiconductor (DMS) confined in all three dimensions (DMS quantum dot). Zn0.93Mn0.07S clusters of not, vert, similar 25 Å diameter are successfully synthesized inside a glass matrix and fully characterized

Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 391-406, June 2026.Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

‘Soft’ phonon modes,structured diffuse scattering and the crystal chemistry of Fe-bearing sphalerites [PDF]
, 2005 Electron diffraction has been used to carefully investigate the reciprocal lattices of a range of iron-bearing sphalerites looking for evidence of Fe clustering and/or Fe/Zn ordering in the form of either additional satellite reflections or a structured ...

Harnessing Interfacial Field Localization in Hexagonal GaP Mie Resonators
Nanophotonics, Volume 15, Issue 9, 13 May 2026.Сharacterization of Mie modes in self‐assembled GaP nanowires grown by MBE in vertical and horizontal configurations. The hexagonal cross‐section suppresses higher‐order modes while preserving dominant low‐order modes with spectral shifts. Simulations and dark‐field spectroscopy confirm the diameter‐dependent tunability.

A geochemical drainage survey of the Fleet granitic complex and its environs [PDF]
, 1978 A regional geochemical drainage reconnaissance programme was undertaken over 900 km2 of south-west Scotland centred on the Fleet granitic complex. Rocks of Ordovician and Silurian age outcrop over the area, into which have been intruded the Fleet and ...
