Gold Deposits and Their Geological Classification

2016-11-20  A rational geological classification of the commonly recognized lode gold deposits is feasible if it is based on the geological settings of the deposits, host rocks, nature of mineralization and geoche m-ical signature. Sixteen common types of bedrock gold deposits are distinguished from one another and their main geological attributes are ...

2021-12-9  The North China Craton is one of China’s major gold-producing areas. Breakthroughs have been continually made in deep prospecting at depths of 500–2000 m in the Jiaodong Peninsula, and geophysical methods have played an important role. Given that the geophysical signals of deep-seated gold deposits are difficult to detect, due to their thick overburden

Orogenic gold and the mineral systems approach:

2016-10-1  Orogenic gold systems (and other mineral and petroleum systems) are short in duration and linked in time and space to tectonic triggers. The latter promote a rapid release of energy (‘avalanches’) that overcome system thresholds and are a strong indicator of complex systems that may show power-law behavior; •.
