New evidence of magmatic-fluid-related phyllic alteration: Implications for the genesis of porphyry Cu deposits [PDF]
, 2002 The phyllic alteration in a number of circum-Pacific porphyry Cu-Au deposits is related to high-temperature saline magmatic fluids. This contradicts the widely used genetic models wherein phyllic alteration formed as the result of mixing between magmatic

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 466-486, March 2026.Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...

Porphyry-type copper deposits, eastern Victoria
ASEG Extended Abstracts, 1999 "Most occurrences of porphyry-type copper mineralisation in Victoria are within the Lachlan Fold Belt in eastern Victoria. Chalcopyrite, chalcocite and pyrite are the main ore minerals. Molybdenum is sometimes present. The mineralised intrusions include the Bete Belong Suite (Double Bull Creek, Sunday Creek, Stringer Knob and Mount Buck prospects), the

Multi‐Scale Electrical Conductivity Model of the Contiguous United States
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The completion of the Magnetotelluric (MT) USArray across the contiguous US enables continental‐scale 3‐D imaging of the asthenosphere‐lithosphere electrical structure. We present a novel 3‐D model of the contiguous United States (MECMUS), derived from a single inversion of the now‐completed USMTArray data set.

Recent Advances in Tailoring Active Site Microenvironments of Fe–N–C Catalysts for Oxygen Reduction
ChemistryEurope, Volume 4, Issue 2, February 2026.This review summarizes the main factors affecting Fe–N–C catalysts for ORR: activity depends on active site structure, electronic configuration, and porosity, while stability is limited by metal leaching, carbon degradation, and inactive phase formation.
