By Hugo Marengo

This publication gathers and updates the main major advances of the final centuries and offers an exceptional micro paleontological research masking greater than 20 stratigraphic sections. this data is supplemented by means of quite a few sedimentological observations and analyses, at the foundation of which a brand new lithostratigraphic framework for the Neogene of the Chacoparanense Basin is proposed.

The booklet is established in an easy-to-read layout: Its major part deals a accomplished overview of the present kingdom of data on transgressions in Argentina and comparable transgressions in different South American nations, considering numerous key points (age, paleoenvironment, micropaleontology, etc.). Secondly, the publication provides the most effects at the TLP and TEP of the Chacoparanense Basin and the TEP of the Península de Valdés. finally, it offers readers with whole stratigraphic profiles (Appendix A), mineralogical analyses (Appendix B), distribution charts (Appendix C), systematics (Appendix D) and plates (Appendix E).

Imagining Sustainable Food Systems

"What defines a sustainable nutrients approach? How can it's extra inclusive? How do neighborhood and worldwide scales have interaction and the way does energy stream inside of meals structures? the right way to motivate an interdisciplinary method of figuring out sustainable meals platforms? and the way to turn on swap? those questions are thought of through european and North American teachers and practitioners during this publication.

Sustainable Living with Environmental Risks

LB x−2) borehole because this section is the best described and has no marine intercalations. A summary of its original description is outlined in Appendix A. 48 2 Results and Discussion Overview The Chaco Formation has the same geographical distribution of the Litoral Group and constitutes most of its thickness. The interbedding of the marine levels of the Laguna Paiva (TLP) and Paraná (TEP) formations allows the separation of this unit into three members, except in the central and western part of the Chaco province and western Formosa provinces, where the continental sedimentation was continuous.

They indicate somewhat different environmental characteristics from those inferred by foraminifera and ostracods. Discoaster broweri is a Cenozoic discoasterid characteristic of temperate-warm waters, whereas Braarudosphaera bigelowi, 40 2 Results and Discussion Thoracosphaera heimii, Rhabdosphaera clavigera, Pontosphaera multipora, and several species of Helicosphaera are indicative of shallow marine nearshore environments, with normal salinity to slightly hyposaline water (Perch-Nielsen 1985).

These microfaunas indicate that the sediments were deposited in a shallow marine environment with changes in salinity. ). Northern Margin of the Salado Basin (Figs. ), calcareous microfossils are very scarce, being also altered by dissolution and pyritization. The pyritization is revealed by the abundance of framboidal pyrite and pyrite casts of microgastropods and foraminifera, whereas solution is suggested by the scarcity or total absence of calcareous material. s. to the bottom, the dissolution and pyritization were less intense, and the foraminifera and ostracod microfaunas have greater diversity and abundance.
