Lode gold deposits are one of the most characteristic features of Archaean greenstone belts within terranes, with major deposits situated in most major cratonic areas (. 1988) Geological setting of gold mineralization in the Norseman-Wiluna Belt, Eastern Goldfields Province, Western Australia.

The so-called & gold deposits are associated with regionally metamorphosed terranes of all ages. Ores were formed during compressional to transpressional deformation processes at convergent plate margins in accretionary and collisional orogens. In both types of orogen, hydrated marine sedimentary and volcanic rocks have been added to continental margins during tens to some 100 million years of collision.

Today, we present the world’s Top 10 producing Gold Mines. This is another newly developed mammoth deposit located in the remote southern reaches of Mongolia. Compiling them was not easy because there are a few ways they can be ranked. 6B to develop and went into production in January 2013.

Part of the Gold exhibition. Gold has been mined from most countries on Earth. Although the mineral occurs in many different types of rock and ore deposits, the deposits themselves are surprisingly similar

Part of the Gold exhibition. Although the mineral occurs in many different types of rock and ore deposits, the deposits themselves are surprisingly similar. For example, most gold occurs in native form-that is, pure or nearly pure-and most gold is not visibly crystalline.

Gold occurs as primary commodity in a wide range of gold deposit types and settings. In the last decade, significant progress has been made in the classification, definition and understanding of the main gold deposit types. Three main clans of deposits are now broadly defined, each including a range of specific deposit types with common characteristics and tectonic settings. The orogenic clan has been introduced to include vein-type deposits formed during crustal shortening of their host greenstone, BIF or clastic sedimentary rock sequences.
