Melting Processes of Pelitic Rocks in Combustion Metamorphic Complexes of Mongolia: Mineral Chemistry, Raman Spectroscopy, Formation Conditions of Mullite, Silicate Spinel, Silica Polymorphs, and Cordierite-Group Minerals

Autor: Igor S. Peretyazhko, Elena A. Savina

Publikováno v: Geosciences, Vol 13, Iss 12, p 377 (2023)

Melted rocks (clinkers and paralavas) of the Mongolian combustion metamorphic (CM) complexes were formed during modern and ancient (since the Quaternary) wild-fires of brown coal layers in the sedimentary strata of the Early Cretaceous Dzunbain Forma

Publikováno v: The Canadian Mineralogist. 58:785-802

Cordierite-group minerals (cordierite and sekaninaite) from granitic pegmatites are often strongly to completely altered to a fine- or coarse-grained mixture of muscovite, chlorite and/or, biotite, along with several less common secondary minerals, i

Selective Contamination of Basaltic Magmas and Genesis of Buchites (on the Example of Shufan Plateau, Primorye)

Autor: S. O. Maksimov, V. M. Chubarov, V. G. Sakhno, N. A. Ekimova

Publikováno v: Doklady Earth Sciences. 489:1402-1408

The problems of large-scale contamination of the Shufan volcanic plateau (Primorye) basalts with selective melts from xenoliths are discussed. Silico-alkaline liquids that are selectively extracted from xenoliths mix only to a limited extent with the

Tourmalines from the late-Variscan Arbus pluton (SW Sardinia) and its metamorphic aureole were structurally and chemically characterized by single-crystal X-ray diffraction, electron and nuclear microprobe analysis, Mossbauer, infrared and optical ab
