Petrographic relations between muscovite-biotite granite and hornblende-biotite granite.

open access: yesThe Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1985
The relationship between muscovite-biotite granite and hornblende-biotite granite was investigated. Chemical analyses satisfying the following three conditions collected from the literature were used to compare the two types of granite; 1) The chemical analysis was of a rock called “granite” by the original author.

Sediment Characteristics and Architecture of Triangular‐Shaped Murtoos: A Test of Murtoo Formation Hypotheses

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Murtoos and murtooized terrains are new types of subglacial landforms found in the Fennoscandian Ice Sheet (FIS) and Cordilleran Ice Sheet (CIS) regions. LiDAR‐based morphometric analyses have revealed substantial morphometric diversity among murtoos and murtoo‐related landforms, while sedimentological excavations have documented a wide range of ...

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

open access: yesGeological Journal, Volume 61, Issue 9, Page 2940-2957, September 2026.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Biotite–Brine Interactions under Acidic Hydrothermal Conditions: Fibrous Illite, Goethite, and Kaolinite Formation and Biotite Surface Cracking

open access: yes, 2016
To ensure safe and efficient geologic CO2 sequestration (GCS), it is crucial to have a better understanding of CO2–brine–rock interactions under GCS conditions. In this work, using biotite (K(Mg,Fe)3AlSi3O10(OH,F)2) as a model clay mineral, brine-biotite

Enhancing Europium Adsorption Effect of Fe on Several Geological Materials by Applying XANES, EXAFS, and Wavelet Transform Techniques

open access: yesToxics
This study conducted adsorption experiments using Europium (Eu(III)) on geological materials collected from Taiwan. Batch tests on argillite, basalt, granite, and biotite showed that argillite and basalt exhibited strong adsorption reactions with Eu.
