Mineralogy of Historic Scheelite Mine Tailings at Glenorchy, Otago, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Otago Schist orogenic mineral deposits with scheelite and gold in the Glenorchy area are mineralogically and geochemically similar to, but structurally different from, those at the active Macraes gold mine in East Otago. Glenorchy veins were mined for scheelite up to 1970s, and an abandoned processing battery site at Glenorchy is now being managed for ...

Seismic imaging of the critical zone of dolerite dykes at Cap Fréhel in Brittany (France)
Near Surface Geophysics, Volume 24, Issue 3, Page 262-288, June 2026.Abstract In June 2023, we measured ten near‐surface seismic profiles to image the critical zone of dolerite (diabase) dykes that cut the sandstone at Cap Fréhel in Brittany (France). Seismic ray tracing and inversion are used to determine the thickness of the regolith layer from first‐arrival P‐wave traveltimes.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The origin of orthogonally spreading ridge segments separated by oceanic transform faults, versus obliquely spreading ridge segments without transform faults (TFs), is a long‐standing enigma of plate tectonics. We address this problem using three‐dimensional (3D) geodynamic models that simulate axial magmatic intrusions along two ridge ...

, 2015 The creative promise of 3D digital fabrication tools is tremendous. However due to the wide range of tools and interfaces, a common static file format called STL is used for sharing designs. While customization tools add creative handles to these digital models, they are often constrained to pre-configured parameters limiting the creative potential of ...
