Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Dynamic multifractal characteristics and damage evolution of granite pegmatite with varying biotite content based on acoustic emission monitoring

International Journal of Mining Science and Technology
Biotite content critically influences rock mechanical behavior and threatens underground engineering stability. Uniaxial compression tests with acoustic emission (AE) monitoring were conducted on granite pegmatite samples having varying biotite content ...

Evaluating the sustainability of mineral water consumption using multi‐scale hydrogeophysics in Caxambu, Brazil

Near Surface Geophysics, Volume 24, Issue 3, Page 234-251, June 2026.
Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

Limitations of the refolding pipeline for de novo protein design

Protein Science, Volume 35, Issue 6, June 2026.
Abstract With the emergence of powerful deep learning‐based tools, computational protein design has become a widely accessible technique. Nowadays, it is possible to perform both sequence and structure design in a matter of minutes, making the technology attractive to the broader scientific community. In protein design campaigns, one of the most common

Eastward Growth of the Tibetan Plateau Linked to Cenozoic Orogenic Wedge Deformation and Fluctuating Melt Sources

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The India–Asia collision continuously loads the Tibetan Plateau (TP), driving its Cenozoic eastward growth. This process has caused extensive crustal deformation and a diverse magmatic response. Here, we report on newly identified 35−6.5 Ma granitoids from Kangding area in southeastern (SE) TP.

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...

Biotite as a petrogenetic discriminator in the polymetamorphosed rocks: A case study from the Champaner supracrustal rocks, Western India

Geosystems and Geoenvironment
The mineral chemistry of Fe-Mg biotite has served as an aid to the petrogenesis of igneous rocks, especially for identifying the parent magma compositions. Though the interpretation of igneous and metamorphic processes utilizing biotite mineral chemistry

Syn‐ to Post‐Collisional Tectonic History of the Paleo‐Tethyan Orogenic Belt: Insights From Triassic Igneous Rocks in the North–Central Tibetan Plateau, China

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The closure of the Paleo‐Tethys Ocean was one of the most important global geological events which formed the framework of the East Asian continent during the early Mesozoic. The Longmu Co‐Shuanghu suture zone is considered to record closure of the main basin of the Paleo‐Tethys Ocean.
