Chemical Discrimination of Rutile From Different Metamorphic Source Rocks: Dealing With Hierarchical Data Structures in Random Forest Classification

Journal of Metamorphic Geology, Volume 44, Issue 2, Page 112-137, February 2026.
ABSTRACT Rutile provides a wealth of petrochronological information in metamorphic geology and due to its high stability during processes of the sedimentary cycle, rutile takes a special position in sedimentary provenance analysis. Besides being one of the classical minerals datable using the U–Pb system, rutile incorporates a broad range of trace ...

Creating a Critical Zone: Feedbacks Between Bedrock Geology, Water Retention, and Vegetation on an Exposed Bedrock Surface, Panola Mountain, Georgia, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.
Abstract Most of Earth's present‐day terrestrial surface is covered by regolith—the layers of soil, saprolite, and weathered bedrock that together comprise the critical zone. Recent research has focused on understanding fluxes of minerals, water, and energy through the critical zone under steady state assumptions.

Mining metal from waste

Geology Today, Volume 42, Issue 1, Page 15-26, January/February 2026.
With the transition to a low carbon future and increasing technological applications, the global demand for metals will continue to rise into the foreseeable future. However, primary ore deposits are finite, and to continue production, lower grade and more complex ore deposits need to be discovered, evaluated and exploited, with increasing exploration ...

Hematite Formation During Skarn Mineralization in the Akatani Iron Deposit, Niigata Prefecture, Japan

Resource Geology, Volume 76, Issue 1, January/December 2026.
The Akatani Fe deposit in NE Japan has been regarded as a skarn deposit because iron‐oxide ores occur within marble‐hosted skarn near the Cretaceous Ninoujidake granite. U–Pb dating of fluorapatite in the skarn indicates that this skarn formed in the Late Cretaceous, contemporaneous with the granite.

Mineralogy Controls on Injection‐Induced Fault Slip

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Fault rocks vary in mineralogy but understanding the role of mineralogy in injection‐induced fault slip behavior remains challenging. We conduct laboratory fluid injection experiments on representative faults with distinct surface mineralogy, injecting fluid at a constant rate of 0.6 mL/min and under a confining pressure of 20 MPa, to examine ...

Study on the Types, and Metallogenic and Diagenetic Environment of Tourmaline from the Zhongzuo Pegmatite Veins in Quyang County, Hebei Province

Yankuang ceshi, 2017
Tourmaline is an efficient tracer during diagenesis and metallogenesis. Chemical composition of tourmaline can not only be used to give information about environment of diagenesis and metallogenesis, but can also be useful in prospecting.
