Tectonic significance of Triassic mafic rocks in the June Complex ...
This study concentrates on the petrological and geochemical investigation of mafic rocks embedded within the voluminous Triassic June Complex of the central Sanandaj-Sirjan zone (Iran), which are crucial to reconstruct the geodynamics of the Neotethyan passive margin. The Triassic mafic rocks are alkaline to sub-alkaline basalts, containing 43.36-49.09 wt% SiO2, 5.19-20.61 wt% MgO and 0. ...

Apr 1, 2021Using jaw crusher and agate mill, five samples from Shang and eight from Dubair were pulverized for whole-rock geochemical analyses. ... Nine of the 14 analyses classify as ferro-pargasite while the remaining five represent ferro-edenite (Fig. 6b). The analyzed biotite is Fe-rich with markedly high molar Fe/Fe + Mg (78−81 %; Table 2).

Other minerals include plagioclase, biotite, ferro-edenite ± riebeckite, titanite, epidote, rutile and magnetite. Apatite, monazite and zircon occur as accessories whereas sericite and kaolinite develop after the alteration of feldspars. At places, plagioclase grains were noticed partially replacing perthites.
