    In:  Supplement to: Hooper, P W P; Weaver, Philip PE (1987): Paleoceanographic significance of late Miocene to early Pliocene planktonic foraminifers at Deep Sea Drilling Project Site 609. In: Ruddiman, WF; Kidd, RB; Thomas, E; et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office), 94, 925-934, https://doi.org/10.2973/dsdp.proc.94.129.1987

    Description: The planktonic foraminifers in 124 samples from Holes 609 and 609B have been analyzed quantitatively to see whether oceanographic events in the late Miocene and early Pliocene (6.5-4.0 Ma) are reflected in the distribution of individual species. Major changes in sea-surface temperature and bottom-water circulation are postulated, mainly on the basis of the coiling-direction ratios in Neogloboquadrina pachyderma (Ehrenberg) and a dissolution index. A cool interval peaking at around 6.2 Ma was followed by climatic fluctuations, possibly indicative of glacial cycles, before a general warming in the Pliocene. Intense dissolution of CaCO3 at this site on both sides of the Miocene/Pliocene boundary is inferred to have resulted from the presence of Antarctic Bottom Water, and an influx of less aggressive North Atlantic Deep Water is indicated at the actual boundary. These climatic and oceanographic changes are tentatively linked to the Messinian salinity crisis in the Mediterranean.

    Notes: The purpose of this study was to evaluate the efficiency of two inoculants of lactic acid bacteria (LAB) on grass silages. The evaluation was made in terms of silage composition, rumen fermentation, digestion and animal production. Over a 2-year period two lots of silage were prepared in two 100-tonne capacity clamps. In each case an untreated silage and an inoculant-treated silage were prepared simultaneously from an identical herbage source using independent sets of silage-making equipment. The inoculant used in the first year was Pioneer Brand 1188 (Pioneer Hi-Bred UK), and in the second year a slightly different inoculant from the same source (Pioneer Hi-Bred) was used. The two inoculants were essentially similar in composition, comprising a mixture of Lactobacillus plantarum and Streptococcus faecalis; the strains included in the second inoculant were selected for their capacity to tolerate higher temperatures. The fermentation of the inoculant-treated silages appeared to be dominated by homofermentative LAB compared with the untreated silages. The use of either inoculant was associated with a change in the rumen volatile fatty acid (VFA) pattern, with a significantly greater molar proportion of propionate and a corresponding reduction in both acetate and butyrate. There was a trend indicating an enhanced efficiency of microbial protein synthesis within the rumen of the heifers for the inoculant-treated silages, although this was only significant when concentrate was offered with the silage in one experiment. The inoculant-treated silages had significantly greater intake characteristics than did the untreated silages, though this was not reflected in a statistically significant improvement in average daily liveweight gain in either year.

    Notes: Abstract Three small sequential Saddle Mountains flows, occupying similar areas on the Columbia Plateau, were erupted over a short interval of time. In the Lewiston Basin area the middle flow of the trio (Lapwai) has intermediate mineralogy and lies on a straight mixing line between the other two flows for virtually all twenty-five elements analyzed. Systematic changes in the ratios of incompatible elements demonstrate that these relationships are a result of magma mixing rather than either crystal fractionation or variable degrees of partial melting. The Lapwai flow has a composition approximately midway between the two homogeneous end members and is itself relatively homogeneous. This implies efficient mixing between equal amounts of Asotin and Wilbur Creek magmas and suggests that mixing was completed in a magma reservoir prior to eruption. The Wilbur Creek and Asotin end members have isotopic features which are believed to result from different degrees of assimilation of crustal material by magma derived from an enriched mantle source (Carlson 1984). The mixing processes described here cannot be related to that earlier mantle/crust mixing process.

    Notes: Abstract In the Western Ghats between latitudes 18° 20′ N and 19° 15′ N, 7000 km2 of Deccan Basalt have been mapped with the primary objective of establishing a flow stratigraphy as a guide to the volcanic history of the flood basalts. Using over 70 measured vertical sections, major and trace element analyses of nearly 1200 samples, and rare-earth and87Sr/86Sr determinations for over 60 samples, we divide the basalt into three subgroups and ten formations. In this paper we describe the seven principal formations in the area and the most prominent individual flows. The Kalsubai Subgroup is formed by the lower five formations, the Jawhar, Igatpuri, Neral, Thakurvadi, and Bhimashankar formations, from botton to top. In these formations amygdaloidal compound flows predominate and have a typically high MgO content, including picrite basalt (〉 10% MgO) and picrite (〉 18% MgO) with phenocrysts of olivine and clinopyroxene. These flows are separated by others which contain giant plagioclase phenocrysts and have more evolved chamical compositions. The Lonavala Subgroup overlies the Kalsubai and is composed of two formations, the Khandala and the Bushe. Both are readily recognized in the field and by their chemical compositions. The Wai Subgroup includes the upper three formations, the Poladpur, the Ambenali, and the Mahabaleshwar. The whole subgroup is composed of simple flows with well-developed flow tops, small phenocrysts of plagioclase, pyroxene and olivine, and relatively evolved bulk compositions. Distribution and variation in thickness of the straitigraphic units within the Western Ghats provide a first comprehensive view of the development of the Deccan volcanic edifice. The persistent southerly dip and gentle southerly plunging anticlinal form of the flows, the lensoid shape of many of the formations, and nearly randomly oriented feeder-dike system are together interpreted as evidence of a central volcanic edifice formed as the Indian plate drifted northward over a mantle plume or hot spot.
