Some say the world will end in fire, some in ice. One more reason to hold with those who favor fire: USC scientists have found that rock and soil breakdown in glaciers generates more acidity and relea...
Redox-sensitive detrital grains such as pyrite and uraninite in sedimentary successions provide one of the most conspicuous geological clues to a different composition of the Archean and early Paleopr...
The Küre volcanogenic massive sulfide deposits lie within the Kastamonu province in the western part of the Pontide tectonic belt of Turkey, and are hosted by ophiolite-related pre-Liassic basaltic s...

The top 20 cm of sediments at active cold seeps in Monterey Bay, coastal California,contain framboidal pyrite that occurs as infillings and pseudomorphs of the chambers of the tests of foraminifera an...
Surface colonization and microbial dissolution of pyrite were studied in the laboratory and by in situ surface colonization experiments conducted at Iron Mountain, California.Laboratory experiments in...
Pyrite has a poor {001} cleavage. Unlike most other minerals with a rocksalt-type structure, pyrite typically fractures conchoidally, demonstrating that parting surfaces are not constrained to the {00...
The reactivity of aqueous Au11 sulfides with FeS2 at pH 5 3 and 6 for temperatures of 25 and 908C has been investigated using X-ray photoelectron spectroscopy (XPS), scan-ning electron microscopy with...
A metal-enriched seawater plume entering the western Mediterranean Sea through the Strait of Gibraltar originates 300 km to the west in the Rio Tinto estuary of southwestern Spain. Mining of Rio Tinto...
Invisible gold in natural and synthetic arsenian pyrite and marcasite correlates with anomalous As content and Fe deficiency, and high contents of invisible gold in most natural and all synthetic ar...
