The behaviour of gold in sedimentary, magmatic and postmagmatic processes are studied and 40 gold-bearing minerals including ten which were recently discovered are described. The results are presented of new experimental studies on phase relations in gold-sulphide systems. The solubility & form of gold migration in high-temperature chloride, sulphide and arsenic solutions are determined. Based on the new data, the genesis of gold deposits is studied and a geochemical classification proposed. This book is designed for specialists in the field of gold chemistry, geochemistry and mineralogy and for field geologists surveying and prospecting for gold.
Until 1945, Indonesia was a Dutch colony known as the Netherlands East Indies. In 1930, the area had over 60 million inhabitants and was a major exporter to Japan, providing some 13 per cent of its oil needs – second only after the United States. Following Germany's occupation of the Netherlands in May 1940, Japan decided to expand its influence in the Netherlands East Indies. Defending the colony was the Royal Netherlands East Indies Army (KNIL). This force, designed primarily for colonial policing, underwent a series of cutbacks in the interwar years before adopting a modernisation programme in 1936, which focused on building up a strike air force, introducing tanks and increasing the firepower of the infantry and artillery. Fully illustrated with period photographs and full-colour artwork, this book examines the dress, insignia, equipment, organization and combat performance of the Royal Netherlands East Indies Army as it faced the all-conquering Japanese forces in World War II.
Recent history should remind us that it was events in the Balkans which sparked off the Great War, with the assassination of the Austrian heir Prince Franz Ferdinand in Sarajevo, and the consequent invasion of Serbia by Austro-Hungarian armies on 2 August 1914. Nevertheless, the subsequent four-year war in that theatre is always overshadowed by the simultaneous campaigns on the Western Front. For the first time this book offers a concise account of these complex campaigns, the organisation, orders of battle, and the uniforms and insignia of the armies involved: Austro-Hungarian, German, Ottoman, Serbian, Montenegrin, Albanian, British, French, Italian, Russian, Bulgarian, Greek and Rumanian.
