Petrographic Evidences for the Origin of Iron in IOCG IronDeposits of Kuh-E-Faryadoon and Kouli-Kosh, Southeast Central Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2013 Kuh-E-Faryadoon and Kouli Kosh iron deposits are hosted by regional metamorphic rocks of Sanandaj-Sirjan zone around Deh-Bid area. Plugs and domes of acid rocks protrude these metamorphic rocks.

Geology of Byobu Rock and Gobanme Rock, Prince Olav Coast, East Antarctica [PDF]
, 2006 We report here the geology of Byobu Rock and Gobanme Rock outcrops hitherto unmapped in the Prince Olav Coast, East Antarctica. Both these outcrops expose high-grade metamorphic and igneous rocks.

Chemistry &Biodiversity, EarlyView.The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (

Recycling Argon through Metamorphic Reactions: the Record in Symplectites [PDF]
, 2018 The 40Ar/39Ar ages of metamorphic micas that crystallized at high temperatures are commonly interpreted as cooling ages, with grains considered to have lost 40Ar via thermally-driven diffusion into the grain boundary network.

The Depositional Record, EarlyView.A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Water pathways and ancient lakes: Flowing towards new models to unravel the past
The Depositional Record, EarlyView.Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.
