    Whole rock and mineral chemistry of intermediate intrusive rocks in the northern side of Shahroud River near Zardkooh in Guilan province (Iran) by Mojtaba Bahajroy, Saeed Taki, Mohssen Moazzen, Alireza Ganji

    Published 2022-10-01
    “…Incidentally, Microprobe analyses results were used to document the precise chemical composition of the rocks studied and the formation conditions of the minerals as well.Geology of the areaThe exposed rock units in the studied area mostly include the Eocene (lava and pyroclastic rocks belonging to the Karaj Formation), but locally the Paleocene (the detrital sedimentary rocks of Fajan Formation), the Permian (the detrital sediments of Dorood and the limestones of Ruteh Formations) and the Carboniferous (the limestone of Mobarak Formation) outcrops and the Oligo-Miocene intrusive bodies are also present.Most of the intrusive masses are composed of gabbroic rocks, but some of them also have intermediate compositions, which are the goal of this research. …”

    Element ∕ Ca ratios in Nodosariida (Foraminifera) and their potential application for paleoenvironmental reconstructions by L. Pacho, L. de Nooijer, G.-J. Reichart, G.-J. Reichart

    Published 2023-10-01
    “…A potential advantage of the Nodosariata is that they appear considerably earlier in the fossil record (Carboniferous) than the Rotaliida (Jurassic), thereby possibly extending the range of foraminifer-based paleoceanographic reconstructions considerably. …”

    Published 2018-07-01
    “…Si pensa spesso che il declino del carbone abbia effetti comuni a tutte le regioni carbonifere. L’articolo individua quattro fattori responsabili delle variazioni regionali: 1) l’economia politica di classe e del controllo industriale; 2) il potere dello stato sulle miniere; 3) l’entità e la diversità delle organizzazioni non governative legate al sistema di controllo industriale; 4) l’attivismo di genere, così come emerge dall'economia politica. …”
