Abstract

Abstract This theisis is submetted for the award M.ScDegree in Geology (Economic Geology) wich consists offive chapters, with the folowing details:- Chapter One deals with an introduction and methods ofinvistigation both in the field and the laprotory. Chapter Two desplays types of ores of ochre, in the Sudan with detailed study for a locality example: Jable Menza - Fadimyia area - Ingessana Hills-Blue Nile State. Geomorphological, Geological and Physiographic features, plust the expected tonnages for this locality have been displayed. The chapter also reffects the production of ochre in the world and its position compared to other coloring materials. Chapter Three deals with some ores ofindustirial minerals and building materials, which are: gypsum, limestone and talc. In the chapter also uses and economic importance of this materials are spelt out. An example locality of limestone, is Jabel Derudeb in the Red Sea Hills. Description of geomorphological, geological and tectonic features together with tonnage is given. The chapter also covers talc ores for wich coardnates, geomorphological and geotectonic characters have been reflected in an example locality viz Qala El Nahal area. Physical and geochemical properties together with the expected tonnage are discussed and compared with other ores of industirial minerals, as for as its economic importantce and uses. Chapter Four discusses the results of the laborotorial work wich were carried out to verify the economic uses of raw matirials discussed above Discussion of the techniques used for simple industralization according to the experments and results of this study is.also covered in this chapter. The chapter also covers the study of the possibility of uses of gypsum and talc in dentestry other engineering properties of gypsum ores in industry have been discussed also. Chapter five summaries the drawn results of this study with some recommendations.
