Fossilized microorganisms associated with zeolite-carbonate interfaces in sub-seafloor hydrothermal environments. A variety of substrates such as active metal surfaces, clay minerals or zeolites could act as surface catalysts. The lower two-thirds of the unit is a medium-grained, lithic, crystal tuff, now largely altered to zeolites but with relict pyroxene and feldspar crystals recognizable. The drug loadings were monitored by thermal analysis and the loaded zeolites were used in several field trials. The section starts with a very good general introduction to zeolites. The zeolites have, however, undergone the greatest change in the 40-odd year interval between the first and second editions. Crystallization of secondary minerals, such as carbonate, clay minerals, zeolites and analcime, occur red from circulating fluids. In order to assess possible disturbance of major-element compositions by zeolite facies alteration, we compare results from immobile trace elements with those from major elements. The slow release of drug from the zeolite matrix improved its efficacy. No veining or major fractures are present and the chalcopyrite clearly pre-dates zeolite crystallization. The amount of drug contained within the zeolite and on the surface was determined by thermogravimetry. Glass shards are altered to zeolites. Claims were also reported of improved weight gain, digestibility and utilization of feed in animals that received zeolite supplements; these also have implications for animals infected with parasites. In regions 2, 3 and 4 combined there was also the tendency for the zeolite groups to have a smaller proportion of worms than the pure drug and control groups.
