Geology of Cuba


Book Description

The evolution of geological cartography in Cuba in its more than 135 years of history has been possible through the consultation of numerous archival reports, publications, maps and personal interviews with different authors and geologists of vast experience. A brief critical analysis is made of the increase in the degree of geological knowledge of the country since the elaboration of the Geological Sketch of the Cuban Island at a scale of 1: 2 000 000 (Fernández de Castro, 1883), first of Cuba and of Ibero-America, until the most recent Digital Geological Map of Cuba at scale 1: 100 000 (Pérez Aragón, 2016). Cuba and its surroundings are a geological mosaic in the southeast corner of the North American plate with rocks from many different origins, from Proterozoic to Quaternary, extended along the southern border of the plate. From the Eocene, this belt has been dissected by several great faults, related to the development of some great oceanic depressions (Cayman trough and Yucatan basin). The fossil record of Cuba, which covers approximately the last 200 million years of life on Earth, is rich in very varied fossils, witnessing a wide diversity of organisms, both animals and plants, that inhabited the Antillean and Caribbean region; and that constitute the inheritance of the biological diversity that the current Cuban archipelago exhibits. As a result of the preparation of the Cuban Metallogenic Map at scale 1: 250 000, forty-one models and eight sub-models of metallic mineral deposits were identified. These models, of descriptive–genetic type, together with the analysis of their spatial distribution and their relationship with geology, allowed the identification and mapping of ten mineral systems, linked to the geodynamic environments present in the Cuban territory. Cuba has large deposits of limestone, loam, dolomite, kaolin, gypsum and anhydrite, rock salt, marbles, sands and clays of different types, zeolites, peat, therapeutic peloids and many more. There are manifestations of decorative and precious rocks such as jasper, jadeite, different varieties of quartz and even xylopals. A compilation of geochemical data of oceanic basalt samples from previous works, together with data of analyzed samples during this study in order to discuss geochemical criteria based on immobile element (proxies for fractionation indices, alkalinity, mantle flow and subduction addition), provide a comprehensive ophiolite classification according to their tectonic setting. This book addresses different facets of the geological knowledge of Cuba: history of its cartography, marine geology, fossil record, stratigraphy, tectonics, classification of its ophiolites, quaternary deposits, metallogeny and minerageny.




Conservation Genetics of New World Crocodilians


Book Description

This book aims to be a comprehensive review of the literature on the conservation genetics of the New World crocodilians, from the biological and demographical aspects of the living species to the application of molecular techniques for conservation purposes. It covers the current status of the molecular genetics applied to phylogenetics, phylogeography, diversity, kinship and mating system, and hybridization, as well its implications for decision making with regards to the conservation of these species at academic and governmental levels. This book can be used as a guide for graduate and undergraduate students to understand how conservation genetics techniques are carried out and how they can help preserve not only crocodilians but also other living species.







Geology of the Cayman Islands


Book Description

Grand Cayman, Little Cayman, and Cayman Brac are, in reality, the summits of independent fault blocks that rise from the depths of the Caribbean Sea. This book traces the geological evolution of these islands over the last 30 to 35 million years. The balance between deposition of carbonate sediments and karst development of the exposed land was dictated by the interaction between ever-changing sea levels and vertical tectonic movement of the fault blocks. Today, drinking water needed for the ever-increasing populations of the islands is supplied largely by desalinization plants that are located in accord with a detailed knowledge of the bedrock. This book is based on an extensive data base that has been assembled over the last 40 years of field work and laboratory analyses. Noteworthy aspects of this database include: Approximately 60 visits to the islands over last 40 years – sampling and documentation of virtually every accessible outcrop on the islands (including some that no longer exist). Most samples have been fully documented petrographically and geochemically. Data from 120 wells that have been drilled to depths up to 245 m (most less than 125 m). Wells have been cored and/or chip sampled. Full documentation of drilling histories, XRD analyses of samples, extensive geochemical analyses for major and minor elements, stable isotopes, 87Sr/86Sr ratios, and Rare Earth Elements from numerous samples. Mapping and sampling of modern sediments, including sediment cores, from most of the lagoons around Grand Cayman. Extensive thin section petrography, scanning electron microscope, and electron microprobe analyses of the dolostones and limestones that form the bedrock of the islands. Samples and data collected from numerous caves on Grand Cayman and Cayman Brac have been used to track their developmental history. Detailed analyses of phosphates collected from Little Cayman. Detailed analyses of terra rossa collected from each of the islands.




The Cayman Islands


Book Description

In the course of the last century a considerable amount of scientific work has been carried out in the Cayman Islands. The results of this (outlined in Chapter 1) are widely distributed in unpublished reports, university theses, various scientific publications and books, many of these sources being difficult to find and some now unobtainable. The purpose of this book, therefore, is to bring all this scattered information together and to present a coherent account of the biogeography and ecology of the Islands, as an easily available reference source and as a foundation on which future work can be based.

The Diario of Christopher Columbus's First Voyage to America, 1492-1493


Book Description

This definitive edition of Columbus's account of the voyage presents the most accurate printed version of his journal available to date. Unfortunately both Columbus's original manuscript, presented to Ferdinand and Isabella along with other evidence of his discoveries, and a single complete copy have been lost for centuries. The primary surviving record of the voyage-part quotation, part summary of the complete copy-is a transcription made by Bartolome de las Casas in the 1530s. This new edition of the Las Casas manuscript presents its entire contents-including notes, insertions, and canceled text-more accurately, completely, and graphically than any other Spanish text published so far. In addition, the new translation, which strives for readability and accuracy, appears on pages facing the Spanish, encouraging on-the- spot comparisons of the translation with the original. Study of the work is further facilitated by extensive notes, documenting differences between the editors' transcription and translation and those of other transcribers and translators and summarizing current research and debates on unanswered current research and debates on unanswered questions concerning the voyage. In addition to being the only edition in which Spanish and English are presented side by side, this edition includes the only concordance ever prepared for the Diario. Awaited by scholars, this new edition will help reduce the guesswork that has long plagued the study of Columbus's voyage. It may shed light on a number of issues related to Columbus's navigational methods and the identity of his landing places, issues whose resolution depend, at least in part, on an accurate transcription of the Diario. Containing day-by-day accounts of the voyage and the first sighting of land, of the first encounters with the native populations and the first appraisals of his islands explored, and of a suspenseful return voyage to Spain, the Diario provides a fascinating and useful account to historians, geographers, anthropologists, sailors, students, and anyone else interested in the discovery-or in a very good sea story. Oliver Dunn received the PH.D. degree from Cornell University. He is Professor Emeritus in Purdue University and a longtime student of Spanish and early history of Spanish America. James E. Kelley, Jr., received the M.A. degree from American University. A mathematician and computer and management consultant by vocation, for the past twenty years he has studied the history of European cartography and navigation in late-medieval times. Both are members of the Society for the History of Discoveries and have written extensively on the history of navigation and on Columbus's first voyage, Although they remain unconvinced of its conclusions, both were consultants to the National geographic Society's 1986 effort to establish Samana Cay as the site of Columbus's first landing.
