Mississippi Valley-Type, Sedex, and Iron Deposits in Lower Cretaceous Rocks of the Basque-Cantabrianate rocks of Lower Cretaceous age. The lower Aptian (Gargasian) horizon contains the economically most important base metal and iron ore deposits. Subordinate ore occurrences are found in a second horizon of upper Aptian to lower Albian age. The ore deposits are found predominantly at platform margi

Trace Element Distribution of Middle-Upper Triassic Carbonate-Hosted Lead-Zinc Mineralizations: The Sb and Ga, increase conspicuously. The resulting zones partly coincide with distinctive geological and paragenetic features. This overlapping suggests a possible genetic connection between the ore geochemistry and the tectonic and depositional evolution of the deposit.

Carbonate-Hosted Pb-Zn Mineralization at Bleiberg-Kreuth (Austria): Compilation of Data and New Aspedicate initial temperatures during ore emplacement from 80 up to 200°C, followed by a temperature increase up to 250°C during late burial diagenesis. Hydrothermal transport of metals and ore formation within a medium to deep burial environment are assumed.

Book 1994 of ore deposits - The association of Mississippi Valley-type ore deposits to diapiric salt structures - Geochemical investigations applied to exploration for sediment-hosted Zn-Pb deposits - Economic aspects. The broad geographical coverage is an additional aspect which will interest both researchers and explorationists.
