- W2181594303 abstract "Sr content and S7S r/3SS r ratio distribution along two sections of the OrciaJioo sttueture (Tuscany, Central Italy) have been investigated. The Orciatico structure consists of a small mafic alkali trachyte laccolith, emplaced in marine Pliocene clays, and of a narrow metamorphic aureole all around. The physical, chemical and mineralogical transformations, which affected clays therein, appear to have been enhanced and spread out by an important hydrothermal circulation (LEONI et aI., 1986). The present data show that such fluids were essentially connale fluids. For strontium no significant transfer from magma to the hosl rock occum:cl; its distribution merely refl~ts migration of connate fluids in equilibrium with marine carbonates. The Sr isotopic composition of the most intensely metamorphosed clays (31Sr~Sr _ 0.71088) is in fact very close to the marine carbonate Sr composition (37S r/USr • 0.70906; HU.DR!::llI and HENDERSON, 19711 and quite different from magmatic rock (37S r/US r • 0.71586) and unmetamorphosed «normal. day (31Sr/USr ' 0.71160) values. Mineralogical data role out the hypothesis that the present Sr isotopic distribution should be due to a mere re-distribution of carbonates foUowing connate fluid circulation; they rather suggest a partial re.equilibration of nco·formed silicate phases with marine Sr. Such PI()oCeSS would have been more advanced in the more intensely metamorphosed zones. The results of the present study are consistent with a mood requiring fluid movements along conv~tive ceUs in an essentially dosed system." @default.
