Chemical Variation of Chromian Spinel Compositions in a Serpentinized Peridotites: Implications for Evolution of the Neoproterozoic Ophiolites

Mineralogical Characteristics of Exsolved Spinel in the Panzhihua V‐Ti Magnetite Deposit, Sichuan: Implications for the Mineralization Process

“…Spinel, a common mineral in igneous and metamorphic rocks in the Earth's crust and upper mantle, is sensitive to changes in physicochemical conditions. Spinel is often used as a key indicator of the formational environment and tectonic background of the rocks within which it occurs, because the chemical constitution of spinel and the mineral assemblage it occurs within not only reveal the physicochemical conditions of its formation but can also provide constraints for petrological and geodynamic inferences (Irvine, 1967;Barnes and Roeder, 2001;Ahmed et al, 2005;Karipi et al, 2007;Guo Guolin et al, 2011;Zeng Linggao et al, 2013;Liu Zhao and Tong Laixi, 2015;Niu Xiaolu et al, 2015;El Dien et al, 2016;Taghipour and Ahmadnejad, 2018).…”
