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 ...

Review of Analytical Lithium Detection and Quantification Methods Along the Lithium Value Chain
Applied Research, Volume 4, Issue 6, December 2025.This article reviews a selection of suitable state‐of‐the‐art analytical methods for different scales of spatial resolution and detection of lithium for a variety of lithium‐bearing materials along the lithium value chain. The various materials differ greatly in terms of their lithium content by more than 5 orders of magnitude and also vary in their ...

Pegmatites of the Mokromoskovsk granite pluton
Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. ЕкологіяIntroduction. The Mokromoskovsky pluton is composed of light gray granites and dark gray granodiorites. Light gray granites are composed of oligoclase (35-40%), microcline (20-25%), quartz (30-35%), and biotite (2-5%).

Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia
New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 531-567, December 2025.ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...
