Alkaline Rocks and Carbonatites of the World

Funded by HiTech AlkCarb - New geomodels to explore deeper for Hi-Tech critical raw materials in Alkaline rocks and Carbonatites



A brief review of occurrences of alkaline igneous rocks in Paraguay, including some petrography, is to be found in Putzer (1962). A similar account is given by Milton and Eckel (1959) with fuller details for some localities, but the coloured geological map of Paraguay accompanying this paper, on which many alkaline intrusions are shown, is not reliable in many instances
