The Petrogenesis of the Permian Podong Ultramafic Intrusion in the Tarim Craton, Western China: Constraints from C-He-Ne-Ar Isotopes

Figure 3

Microphotos of different types of fluid inclusions in the Podong ultramafic intrusion, China. (a) Primary fluid inclusions in pyroxene of sample PD73-1, plane polarized light (-); (b) primary fluid inclusions in olivine of sample PD73-2, plane polarized light (-); (c) secondary fluid inclusions in plagioclase of sample PD73-5, perpendicular polarized light (+). Olv = olivine; Pyx = pyroxene; Pl = plagioclase; Phl = phlogopite; Po = pyrrhotite.
