摘要: Abstract The Vila de Cruces ophiolite is one of the ophiolitic units involved in Variscan suture northwest Iberian Massif. This consists a tectonically repeated succession greenschist facies volcanic rocks, common alternations metasediments pelitic or siliceous character, and scarce orthogneisses, metagabbros, serpentinites. protolith age granitic orthogneiss that intruded mafic rocks dated at \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc} \newcommand\cyr{ \renewcommand\rmdefault{wncyr} \renewcommand\sfdefault{wncyss} \renewcommand\encodingdefault{OT2} \normalfont \selectfont} \DeclareTextFontCommand{\textcyr}{\cyr} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} \landscape $497\pm 4$ \end{document} Ma (U‐Pb in...
