The Roles of Transcrustal Magma- and Fluid-Conducting Faults in the Formation of Mineral Deposits
GeosciencesIn this article, we consider the roles of transcrustal magma- and fluid-conducting faults (TCMFCFs) in the formation of mineral deposits, showing the importance of deep sources of heat and hydrothermal solutions in the genesis and history of deposit ...

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is

Petrochemistry of the granitic rocks in the Chungju, Wolaksan and Jecheon granite batholiths
, 1989 본 연구는 옥천 습곡대 중부에 분포하고 있는 쥬라기의 대보 화강암류인 충주, 제천 화강암과, 백악기 불국사 화강암류인 월악산, 무암사, 속리산 화강암의 광물 암석화학적 특징과 암석 성인을 규명하고, 이와 밀접히 관계하면서 분포하고 있는 황강리 광화대의 광화 작용과 화강암류의 관련성을 검토하였다. 이를 위해 상기 지역 화강암류외에 원주.강릉.보은 지역 일부 화강암류도 비교 분석하였다. 모드 분석과 norm 분석에 의하면 월악산, 무암사, 원주 화강암은

Granitic magmas: possible and impossible sources, water contents, and crystallization sequences
, 1976 The calc-alkalic rocks of batholiths or their precursors may be generated in deep continental crust, in subducted oceanic crust, in the mantle wedge above, or in processes involving material from all three sources. For the series gabbro–tonalite–granite,
