Transmitted light photomicrographs of fluid inclusions (FIs) hosted in wolframite-bearing quartz veins from the Puy-les-Vignes deposit (sample PLV-7591, “filon 2”; sample PV-1, “filon T18”). (A) Isolated primary Lc-w surrounded by a halo of small neonate fluid inclusions (nFI) resulting from post-entrapment reequilibration. (B) Elongated cluster of decrepitated FIs possibly located at a growth zone boundary. (C) Cluster of decrepitated primary FIs cut by two pseudosecondary (ps) fluid inclusion planes (FIP) of regular Lw-c. (D) Clusters of partly decrepitated Lc-w cut by pseudosecondary FIP of partly decrepitated Lw-c and by secondary (s) FIP of regular Lw. (E) Pseudosecondary FIP of Lw-c, partly decrepitated, located at grain boundaries. (F) Isolated irregular three-phase Lc-w containing a carbonic liquid phase (L_car), a carbonic vapor phase (V_car), and an aqueous liquid phase (L_aq). (G) Very irregular two-phase FI showing an “atoll-like” stretching texture. (H) Isolated regular three-phase Lc-w. (I) Highly irregular three-phase Lc-w. (J) Isolated irregular three-phase Lc-w. (K) Two-phase Lw-c having variable vapor to liquid ratios. (L) Regular two-phase Lw-c along a pseudosecondary FIP. (M) Cluster of irregular two-phase Lw-c (sample PLV-02-12). (N) Isolated regular two-phase Lw-c. (O) Secondary FIP of regular two-phase Lw. (P) Regular two-phase Lw along a secondary FIP.
