Whole-rock SiO2, Al2O3 and Na2O were determined by X-ray fluorecense spectrometry, whereas acid-soluble Mg, Ca, Fe, Mn and Sr were determined by inductively coupled plasma-atomic emission spectrometry.
- * - altered Sr isotope ratios.
Sr isotope ratios indicated by bold-face letters were obtained at Institute of Geology and Geochronology in St. Petersburg, Russia; Sr isotope ratios in normal-face letters were obtained at Laboratoire des Mécanismes et Transferts en Géologie, Université Paul-Sabatier, Toulouse, France.
C and O isotope ratios indicated by bold-face letters were obtained at Scotish Universities Environmental Research Centre in Glasgow, Scotland.	
C, O and Sr isotope ratios indicated by normal-face letter are from Pokrovsky et al. (2006a). 								
Abbreviations used: ML - micritic limestone, MRL - marl, MSL - microsparitic limestone, MCRSL - microbial stromatolitic limestone, SD- sandstone dyke, SND - sandstone, CV- calcite vein, OOL- oolitic limestone, ONK - oncolitic limestone, CA- calcarenite; FPC - flat-pebble conglomerate.
