A Machine Learning Zircon Trace Element Tool to Predict Porphyry Deposit Type and Resource Size

open access: yesJournal of Geophysical Research: Machine Learning and Computation
Porphyry deposits are primarily known for their association with base metals like copper and to some extent molybdenum and gold. Here we present machine learning models, based on zircon composition, that provide quantitative distinction between different

The Occurrence and Morphology of Naturally Occurring Respirable Mordenite Mineral Fibres in New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Mordenite is a naturally occurring zeolite mineral that is the seventh most common zeolite mineral globally, forming at low temperatures (≥100°C) in hydrothermal systems. In New Zealand, extensive deposits of mordenite are commonly associated with areas of hydrothermal alteration, particularly in the Coromandel and Taupo Volcanic Zones.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

open access: yesLand Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...
