M., Brickles, S. L., Licht, K. J., & Monaghan, G. W. (2017). Exploring the use of zircon geochronology as an indicator of Laurentide Ice Sheet till provenance, Indiana, USA. Quaternary Research, 88(3), 525–536. https://doi.org/10.1017/qua.2017.71 Abstract A pilot study was designed to evaluate the potential of zircon geochronology as a provenance indicator of till from the Lake Michigan, Saginaw, and Huron-Erie Lobes of the Laurentide Ice Sheet. Based on existing ice flow-path models, we hypothesized that till from each lobe would have different zircon age population distributions because the lobes originated from regions of the Canadian Shield with different bedrock ages. After correcting for zircon fertility, the majority of grains in all till samples are 1600–950 Ma, with ~30% of ages >2500 Ma. This similarity means that till from the three lobes cannot be clearly differentiated based on their zircon populations. The dominant ages found and the homogeneity of distributions in the till indicates a non-Shield source and instead reflect an origin from some combination of underlying till and sedimentary bedrock in the Great Lakes region. -

They are classically referred either to uniloc- ular parathuramminid foraminifera, algae incertae sedis or calcispheres (e.g., Bisphaera, Cribrosphaeroides, Uslo nia, Vermiporella myna, Irregularina). Due to their morphology and microstructural features, they are interpreted here as possibly belonging to Thaumatoporella PIA, a widespread Mesozoic-Early Cenozoic taxon of incertae sedis showing a remarkably high morphological variability. In analogy to Mesozoic thaumatoporellaceans, Bisphaera ma levkensis BIRINA is interpreted as the cyst (i.e.= resting) stage of forms ascribed to different genera, i.e., Cribro sphaeroides, Uslonia and Vermiporella (here: Vermiporella myna WRAY). Note that in the Mesozoic many taxa were also synonymized with Thaumatoporella: Polygonella ELLIOTT, Lithoporella elliotti (EMBERGER), Messopota mella DRAGASTAN et al., Vermiporella crisiae DRAGASTAN et al., Micritosphaera SCOTT. This new interpretation, based on material from the Devonian of W-Germany and the Czech Republic, leads to taxonomic reassessment as Thaumatoporella? malevkensis (BIRINA) nov. -

Terrestrial Ecosystems on the Mesozoic Peri-Adriatic Carbonate Platforms: the Vertebrate Evidence
Asociación Paleontológica Argentina. Publicación Especial 7 ISSN 0328-347X VII International Symposium on Mesozoic Terrestrial Ecosystems: 77-83. Buenos Aires, 30-6-2001 Terrestrial ecosystems on the Mesozoic peri-Adriatic carbonate platforms: the vertebrate evidence Fabio M. DALLAVECCHIN Abstract. The remains of Mesozoic carbonate platforms outcrop along the margins of the Adriatic Sea and the mountain chains surrounding them in Italy, Slovenia and Croatia. Despite the fact that the platforms were far from continents, abundant evidence of terrestrial vertebrates was recently found, mainly in the Norian, Lower Jurassic and Cretaceous, and is here reviewed. The presence of populations of large ter- restrial vertebrates (mainly dinosaurs) on these carbonate platforms, and in particular the discovery of late Hauterivian-early Barremian sauropods and late Santonian hadrosaurids, has important paleoecological and paleogeographical implications.

New Insights on Secondary Minerals from Italian Sulfuric Acid Caves Ilenia M

Italy hosts ~25% of the known worldwide sulfuric acid speleogenetic (SAS) systems, including the famous well-studied Frasassi, Monte Cucco, and Acquasanta Terme caves. Nevertheless, other underground environments have been analyzed, and interesting mineralogical assemblages were found associated with peculiar geomorphological features such as cupolas, replacement pockets, feeders, sulfuric notches, and sub-horizontal levels. In this paper, we focused on 15 cave systems located along the Apennine Chain, in Apulia, in Sicily, and in Sardinia, where copious SAS minerals were observed. Some of the studied systems (e.g., Porretta Terme, Capo Palinuro, Cassano allo Ionio, Cerchiara di Calabria, Santa Cesarea Terme) are still active, and mainly used as spas for human treatments. The most interesting and diversified mineralogical associations have been documented in Monte Cucco (Umbria) and Cavallone-Bove (Abruzzo) caves, in which the common gypsum is associated with alunite-jarosite minerals, but also with baryte, celestine, fluorite, and authigenic rutile-ilmenite-titanite. -

Giannandrea <[email protected]> ABSTRACT: The geological/geomorphological map of Putignano town (Bari, Southern Italy) contains useful evidence of landforms and sedimentary successions in both urbanized and industrial areas, contributing also to a better understanding of floodings dur- ing high-magnitude pluviometric events in the area. The analyzed flooded areas correspond to surfaces karst landforms with differ- ent shapes and sizes. Our detailed geological/geomorphological study shows that most of the industrial area of Putignano was built on Cretaceous calcareous units in a depressed area, which corresponds to an extensive endorheic basin (locally called "il Basso"). Part of the local urban expansion, built from 1950 to present day, occupies the most depressed areas of numerous karst valleys that, despite this urbanization, still preserve their hydraulic function. Usually these geological and geomorphological fea- tures are not yet completely identified and, unfortunately, not taken into consideration in the planning stages of the urban expan- sion and industrial settlement.
