Strontium-Isotope Stratigraphy As a Constraint on the Age of Condensed Levels: Examples from the Jurassic of the Subbetic
Strontium-isotope stratigraphy as a constraint on the age of condensed levels: examples from the Jurassic of the Subbetic Zone (southern Spain) LUIS M. NIETO*, PEDRO A. RUIZ-ORTIZ*, JAVIER REY and Ma ISABEL BENITOà * Dpto. de Geologı´a, Universidad de Jae´n, E-23071 Jae´n, Spain (E-mail: [email protected]) Dpto. de Geologı´a, EPS Linares, Universidad de Jae´n, E-23700 Jae´n, Spain àDpto. de Estratigrafı´a, U.E.I. Correlaciones Estratigra´ ficas, Universidad Complutense de Madrid-CSIC, E-28040 Madrid, Spain ABSTRACT Condensed levels are often characterized by reworked fossils that may lead to incorrect age assessments. Strontium-isotope stratigraphy is an important chronostratigraphic tool that can be used to verify the biostratigraphic information from condensed beds. This paper describes a study of the 87 Sr/86Sr isotope ratios of 56 belemnite samples collected from 28 stratigraphic sections of the boundary between the Upper Member of the Gavila´n Formation and the Zegrı´ Formation (Pliensbachian, Subbetic Zone). The petrographic and geochemical data (d18O, d13C, concentrations of Fe, Mn and Mg, and the Sr/Mn ratio) suggest that the belemnites have preserved their original marine geochemical composition. After plotting the samples in diagrams of 87Sr/86Sr values against time according to their biostratigraphic age, four different groups (A, B, C and D) were obtained with respect to the reference curve. In groups A and B, the age deduced from the Sr-isotope ratio is in total or partial agreement, respectively, with the biostratigraphic age; therefore the 87Sr/86Sr ratio is a good method for the dating, correlation and assessment of biostratigraphic results. -

The Political Culture of Free People of African Descent in Eighteenth-Century New Granada (1750-1810)
THE POLITICAL CULTURE OF FREE PEOPLE OF AFRICAN DESCENT IN EIGHTEENTH-CENTURY NEW GRANADA (1750-1810) by Katherine Bonil Gómez A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy Baltimore, Maryland February, 2017 © _2017 Katherine Bonil Gómez All Rights Reserved ABSTRACT This dissertation is a study of the lives and political culture of free people of African descent in eighteenth-century Colombia. It explores the ways in which free people of African descent interacted with the Hispanic monarchy institutions and how these interactions shaped their conception of their membership in the body politic and constituted themselves as political subjects. I analyze the ways in which these subjects were incorporated to the Monarchy, how they understood, claimed and negotiated this membership, and how, in this process, they forged their own political notions. I pay attention to the different repertoires of actions of free people and analyze the different ways in which they manifested discontent and participated in politics. Chapter 1 offers an overview of the population of free people in eighteenth-century Colombia. Chapters 2, 3, and 4 delve into three different groups of free people, traders, fluvial workers, and urban and rural poor. Chapter 5 explores participation free people of African descent in one of the largest upheavals of the colonial era, the Comunero revolt. I argue that the corporative and jurisdictional nature of the composite Hispanic monarchy had enduring effects on the ways in which free people of African descent imagined and framed their relation to the state. Free vassals of African descent were not allowed a corporate existence as indigenous group. -

VARI I SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 564 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -
