Multidisciplinary Investigation of Healy Submarine Volcano (Kermadec Arc, New Zealand) Using AUV and Submersible Data: Structural Control on Magmatic and Hydrothermal Processes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).

Marine volcanosedimentary basins hosting porphyry Au-Cu deposits, Cadia Valley, New South Wales, Australia

, 2014
The volcanosedimentary rocks that host the Au-rich porphyry Cu deposits of the Cadia Valley preserve the products of episodic volcanism that erupted into a large sedimentary basin.

Middle Cretaceous Andean‐Type Arc Evolution in the Sanandaj–Sirjan Zone (Shalair Valley), Iraq: New Geochronological and Geochemical Constraints

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±

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.

Finite Element Modelling of Synthetic Normal Resistivity Logging Tool: Insights Into Vein Parameters, Borehole Fluids and Electrode Configuration

Geophysical Prospecting, Volume 74, Issue 5, June 2026.
ABSTRACT Borehole resistivity logging can play an important role in subsurface exploration by enhancing the accuracy of surface data inversion models. However, its application in the mining industry remains limited due to challenges posed by complex geological formations, particularly in vein‐hosted deposits such as orogenic gold and porphyry copper ...

Greek Commodities in Phoenicia: An Interdisciplinary Study of Imported Amphorae From Tell el‐Burak (Lebanon)

Archaeometry, Volume 68, Issue 3, Page 395-408, June 2026.
ABSTRACT This paper examines transport amphorae of Greek/Aegean types from the 7th–4th c. BCE imported to the Phoenician coastal settlement of Tell el‐Burak, Lebanon. We present a selection of 58 pieces analyzed by typological, chemical (NAA), and petrographic approaches.

Magmatic Evolution at the Saindak Cu-Au Deposit: Implications for the Formation of Giant Porphyry Deposits

The Chagai porphyry copper belt is a major component of the Tethyan metallogenic domain, which spans approximately 300 km and hosts several giant porphyry copper deposits. The tectonic setting, whether subduction-related or post-collisional, and the deep
