Climatic Events During the Late Pleistocene and Holocene in the Upper Parana River: Correlation with NE Argentina and South-Central Brazil Joseh C
Quaternary International 72 (2000) 73}85 Climatic events during the Late Pleistocene and Holocene in the Upper Parana River: Correlation with NE Argentina and South-Central Brazil JoseH C. Stevaux* Universidade Federal do Rio Grande do Sul - Instituto de GeocieL ncias - CECO, Universidade Estadual de Maringa& - Geography Department, 87020-900 Maringa& ,PR} Brazil Abstract Most Quaternary studies in Brazil are restricted to the Atlantic Coast and are mainly based on coastal morphology and sea level changes, whereas research on inland areas is largely unexplored. The study area lies along the ParanaH River, state of ParanaH , Brazil, at 223 43S latitude and 533 10W longitude, where the river is as yet undammed. Paleoclimatological data were obtained from 10 vibro cores and 15 motor auger holes. Sedimentological and pollen analyses plus TL and C dating were used to establish the following evolutionary history of Late Pleistocene and Holocene climates: First drier episode ?40,000}8000 BP First wetter episode 8000}3500 BP Second drier episode 3500}1500 BP Second (present) wet episode 1500 BP}Present Climatic intervals are in agreement with prior studies made in southern Brazil and in northeastern Argentina.

Palaeogene Marine Stratigraphy in China
LETHAIA REVIEW Palaeogene marine stratigraphy in China XIAOQIAO WAN, TIAN JIANG, YIYI ZHANG, DANGPENG XI AND GUOBIAO LI Wan, X., Jiang, T., Zhang, Y., Xi, D. & Li G. 2014: Palaeogene marine stratigraphy in China. Lethaia, Vol. 47, pp. 297–308. Palaeogene deposits are widespread in China and are potential sequences for locating stage boundaries. Most strata are non-marine origin, but marine sediments are well exposed in Tibet, the Tarim Basin of Xinjiang, and the continental margin of East China Sea. Among them, the Tibetan Tethys can be recognized as a dominant marine area, including the Indian-margin strata of the northern Tethys Himalaya and Asian- margin strata of the Gangdese forearc basin. Continuous sequences are preserved in the Gamba–Tingri Basin of the north margin of the Indian Plate, where the Palaeogene sequence is divided into the Jidula, Zongpu, Zhepure and Zongpubei formations. Here, the marine sequence ranges from Danian to middle Priabonian (66–35 ma), and the stage boundaries are identified mostly by larger foraminiferal assemblages. The Paleocene/Eocene boundary is found between the Zongpu and Zhepure forma- tions. The uppermost marine beds are from the top of the Zongpubei Formation (~35 ma), marking the end of Indian and Asian collision. In addition, the marine beds crop out along both sides of the Yarlong Zangbo Suture, where they show a deeper marine facies, yielding rich radiolarian fossils of Paleocene and Eocene. The Tarim Basin of Xinjiang is another important area of marine deposition. Here, marine Palae- ogene strata are well exposed in the Southwest Tarim Depression and Kuqa Depres- sion. -

The section covers almost the entire Lutetian and ranges into the Priabonian. It is part of the Helvetic (tectonic) Unit and represents the sedimentary processes that took place on the southern shelf to upper bathyal of the European platform at that time. Six lithologic units occur in the Adelholzen-Section: 1) marly, glauconitic sands with predominantly Assilina, 2) marly bioclastic sands with predominantly Nummulites, 3) glauconitic sands, 4) marls with Discocyclina, 5) marly brown sand. These units were combined as “Adelholzener Schichten” and can be allocated to the Kressenberg Formation. -

Biju-Duval, Institut Français du Pétrole, 92500 Rueill-Malmaison ABSTRACT Formations penetrated at Site 372 are compared with series cropping out on land in the Balearic Islands, Southern Spain, and Sardinia. The comparison is extended to wells drilled in the Gulf of Lion. The margin at Menorca and the North Balearic Provencal Basin appear to be at least of Burdigalian age. The entire Miocene is undisturbed at Site 372 in contrast to Mallorca and continental Spain where important tectonic events occurred during middle and upper Miocene. INTRODUCTION By comparing these rocks with those of Mallorca, Bourrouilh considered the age of tectonism to be Because DSDP Site 372 is located only 40 km from middle Miocene. This conclusion is questionable con- the Balearic Islands, it is logical to compare the series sidering that at Site 372 the entire Miocene is undis- penetrated at the site with land equivalents, particu- turbed. -

The Stratigraphic Architecture and Evolution of the Burdigalian Carbonate—Siliciclastic Sedimentary Systems of the Mut Basin, Turkey
The stratigraphic architecture and evolution of the Burdigalian carbonate—siliciclastic sedimentary systems of the Mut Basin, Turkey P. Bassanta,*, F.S.P. Van Buchema, A. Strasserb,N.Gfru¨rc aInstitut Franc¸ais du Pe´trole, Rueil-Malmaison, France bUniversity of Fribourg, Switzerland cIstanbul Technical University, Istanbul, Turkey Received 17 February 2003; received in revised form 18 November 2003; accepted 21 January 2004 Abstract This study describes the coeval development of the depositional environments in three areas across the Mut Basin (Southern Turkey) throughout the Late Burdigalian (early Miocene). Antecedent topography and rapid high-amplitude sea-level change are the main controlling factors on stratigraphic architecture and sediment type. Stratigraphic evidence is observed for two high- amplitude (100–150 m) sea-level cycles in the Late Burdigalian to Langhian. These cycles are interpreted to be eustatic in nature and driven by the long-term 400-Ka orbital eccentricity-cycle-changing ice volumes in the nascent Antarctic icecap. We propose that the Mut Basin is an exemplary case study area for guiding lithostratigraphic predictions in early Miocene shallow- marine carbonate and mixed environments elsewhere in the world. The Late Burdigalian in the Mut Basin was a time of relative tectonic quiescence, during which a complex relict basin topography was flooded by a rapid marine transgression. This area was chosen for study because it presents extraordinary large- scale 3D outcrops and a large diversity of depositional environments throughout the basin. Three study transects were constructed by combining stratal geometries and facies observations into a high-resolution sequence stratigraphic framework. 3346 m of section were logged, 400 thin sections were studied, and 145 biostratigraphic samples were analysed for nannoplankton dates (Bassant, P., 1999. -
The Geologic Time Scale Is the Eon
Exploring Geologic Time Poster Illustrated Teacher's Guide #35-1145 Paper #35-1146 Laminated Background Geologic Time Scale Basics The history of the Earth covers a vast expanse of time, so scientists divide it into smaller sections that are associ- ated with particular events that have occurred in the past.The approximate time range of each time span is shown on the poster.The largest time span of the geologic time scale is the eon. It is an indefinitely long period of time that contains at least two eras. Geologic time is divided into two eons.The more ancient eon is called the Precambrian, and the more recent is the Phanerozoic. Each eon is subdivided into smaller spans called eras.The Precambrian eon is divided from most ancient into the Hadean era, Archean era, and Proterozoic era. See Figure 1. Precambrian Eon Proterozoic Era 2500 - 550 million years ago Archaean Era 3800 - 2500 million years ago Hadean Era 4600 - 3800 million years ago Figure 1. Eras of the Precambrian Eon Single-celled and simple multicelled organisms first developed during the Precambrian eon. There are many fos- sils from this time because the sea-dwelling creatures were trapped in sediments and preserved. The Phanerozoic eon is subdivided into three eras – the Paleozoic era, Mesozoic era, and Cenozoic era. An era is often divided into several smaller time spans called periods. For example, the Paleozoic era is divided into the Cambrian, Ordovician, Silurian, Devonian, Carboniferous,and Permian periods. Paleozoic Era Permian Period 300 - 250 million years ago Carboniferous Period 350 - 300 million years ago Devonian Period 400 - 350 million years ago Silurian Period 450 - 400 million years ago Ordovician Period 500 - 450 million years ago Cambrian Period 550 - 500 million years ago Figure 2. -
