Colle Fabbri

Major element compositions for the Colle Fabbri rocks are extremely variable for such a small outcrop (e.g. Si02 = 43-64 wt % CaO = 4 to 37 wt %). Rare-earth elements (REE) are moderately enriched and fractionated, and contain an important negative Eu anomaly. 87Sr/86Sr ratios range from 0.7077 to 0.7119 and 143Nd/144Nd ratios vary from 0.71115 to 0.71192 (Melluso et al. 2003).
