Emplacement of Hybrid Continental‐Oceanic Arc Terranes Without Collision: The Devonian Calliope Arc (New England Orogen, Australia)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The accretion of allochthonous provinces, derived from oceanic plates, has traditionally been considered an important contributor to continental growth. However, increasing evidence shows that some oceanic terranes (e.g., island arcs) are not “exotic,” as suggested by the presence of continental‐derived sedimentary provenance.

Re-Os Isotopic Dating of Arsenopyrite from Auriferous Quartz Vein-type Gold Deposits in the Southwestern Margin of Jiangnan Orogen

Yankuang ceshi, 2016
Quartz vein-type gold deposits of Southeastern Guizhou Province in the southwestern margin of Jiangnan Orogen, which are typical orogenic gold deposits, are hosted in Neoproterozoic Banxi Group sub-greenschist facies metamorphic rocks.

Efficiency of singularity and PCA mapping of mineralization-related geochemical anomalies: a comparative study using BLEG and <180μm stream sediment geochemical data

Bulletin of the Mineral Research and Exploration, 2022
In gold (Au) exploration, the analysis of both bulk leach extractable gold (BLEG) and acid-extractable Au in the <180μm stream sediment fraction are the two most common approaches.

The Role of Mafic Intrusion in Seismotectonics: Insights From the 1668 M 8.5 Tancheng Earthquake Rupture Zone Along the Tan‐Lu Fault Zone, Eastern China

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tan‐Lu Fault Zone (TLFZ), the largest lithosphere‐scale strike‐slip fault in eastern China, has experienced multiple tectonic stages and remains high seismic activity, including the 1668 Tancheng earthquake (M 8.5). Here we employ dense‐array receiver functions to resolve crustal thickness, Vp/Vs ratio, and seismic discontinuities in the ...

Pleistocene and Holocene Mobility of Detrital Platinum in Southern New Zealand: Review and Regional Synthesis

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Detrital platinum group minerals (PGM) are rare and distinctive in Pleistocene–Holocene sedimentary systems of the southern South Island, thereby enabling tracking of their long‐distance transport for ∼200 km. The first ∼100 km of transport involved Pleistocene glaciofluvial processes southwards down the Waiau River, where PGM (principally Pt–Fe and Ru–

Alteration Alteration, Mineralization and Geochemistry of Metamorphic Rocks Hosted Hydrothermal Gold Deposit at Rumbia Mountains, Bombana Regency, Southeast Sulawesi, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2019
In Indonesia, gold is commonly mined from porphyry, epithermal and skarn type deposits that are commonly found in volcanic/magmatic belts. However, were recently numerous gold prospects discovered in association with metamorphic rocks.

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 ...

A Review of Carboniferous-Triassic Tectonic-Magmatic Evolution of Luang Prabang–Loei Metallogenic Belt in Laos and Thailand and Implications for Gold–Copper Mineralization

Geosciences
The Luang Prabang (Laos)–Loei (Thailand) metallogenic belt is located on the northwestern margin of the Indochina Block. It is one of the most important gold–copper metallogenic belts in Southeast Asia.
