Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The mineralized area is a part of ancient failed rift including a basaltic belt extended across Central Sudan passing through Thetis ,Atlantis-II, and Valdivia deeps of the Red Sea , and on to the Jeddah and El-Riyadh cities in Saudi-Arabia. A scanning electron microscope with an X-ray microprobe attachment was used for detailed analysis of coexisting mineral chemistry. Micro textural analysis for thermal features indicated crystallization from boiling solution (hyaloclastic and colloform microtextured); simple cooling (diablastic); replacement (pseudomorphs) and alteration and fissure filling (Nematobiastic). 64 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This review is drawn into theoretical, field, and experimental studies in two main areas. The first area involves the investigation of the physical and chemical characteristics of iron (Fe) and manganese (Mn) deposits, and the development of genetic models for use in mineral exploration. The second area deals with the nature of geothermal systems against weathering system as two different sources of the Fe and Mn. It includes inspection of mechanisms of transportation and chemical and biochemical effects during and after the initial deposition and the development of concentrations of Fe and Mn during diagenesis. Available data on physical and chemical properties of recent Fe and Mn deposits are collected and the anticipated diagenetic cycles required for their lithificatoin are discussed on bases of stabilities of iron or manganese minerals or both. To explain the association between diagenesis and Fe and Mn deposits, many examples mostly from unpublished experimental studies carried out by the writer are provided herein. 104 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -La zona mineralizada forma parte de un antiguo rift fallido que incluye un cinturón basáltico que se extiende por el centro de Sudán, pasando por las profundidades de Thetis, Atlantis-II y Valdivia del Mar Rojo, y hasta las ciudades de Jeddah y El-Riyadh en Arabia Saudí. Se utilizó un microscopio electrónico de barrido con una microsonda de rayos X para el análisis detallado de la química mineral coexistente. El análisis microtextural de las características térmicas indicó la cristalización a partir de una solución en ebullición (hialoclástica y microtextura coloforme); el enfriamiento simple (diablástica); la sustitución (pseudomorfos) y la alteración y el relleno de fisuras (nematobiástica). 68 pp. Spanisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Das mineralisierte Gebiet ist Teil eines alten, gescheiterten Grabens, der einen Basaltgürtel umfasst, der sich über den Zentralsudan durch die Thetis-, Atlantis-II- und Valdivia-Tiefen des Roten Meeres bis zu den Städten Jeddah und El-Riyadh in Saudi-Arabien erstreckt. Ein Rasterelektronenmikroskop mit einer Röntgenmikrosonde wurde zur detaillierten Analyse der vorhandenen Mineralchemie eingesetzt. Die mikrostrukturelle Analyse der thermischen Merkmale deutete auf Kristallisation aus siedender Lösung (hyaloklastisch und kolloform mikrotexturiert), einfache Abkühlung (diablastisch), Austausch (Pseudomorphosen) sowie Alteration und Rissfüllung (nematobiastisch) hin. 72 pp. Deutsch.…
