quartz and scheelita de Poblet, with an NE-SO orientation, are embedded in the tardi-hercinic calcic granites of the southern Catalan Coastal Chains. The study of fluid inclusions in quartz and scheelite of these filons has been carried out using microthermometria, Raman microspectroscopy and electron microscopy with EDS analysis. For both types of minerals, the same types of intracristalline cavities have been observed, with the exception of type I inclusions, which have not been identified in scheelite. They have been characterised successively: — Type I hypersaline inclusions containing only halite, or several associated solids: silvine and ferrous chloride (child minerals) ankerite, steel-iron, moscovite, calcium feldspar (trapped minerals). — Low salinity type II (L) aqueous inclusions (1 to 6 % eq. NaCl), which homogenise in a liquid phase between 300 and 400 °C, or under critical conditions around 400 °C — low salinity type II (V) aqueous inclusion with a low density carbon phase, homogenising in the gas phase between 350 and 420 °C including type II (V ') triphasic inclusions, in which the gaseous phase consists of practically pure CO2, of density 0,26. These type II inclusions seem to represent the continuous evolution of a supercritical fluid towards two sub-critics. — Late type III inclusions indicating the circulation of a colder and diluted aqueous fluid (150 at 300 °C and 0 to 3.5 % eq. NaCl). Abundance of ferrous chloride type I inclusions suggests a high temperature (400 to 600 °C) of a fluid phase atrape in equilibrium with a biotytic granite (Whitney et al., 1985). P-T conditions compatible with the measurements obtained in type II inclusions are around 400 °C and 0,8 kbar, comparable to those obtained at the tungsten deposit of Jebel Aouam, Morocco (Cheilletz, 1984). These conditions could correspond to those of the crystallisation of scheelita.
