Three stages have been identified in the Tianger gold deposits. Stage I occurs at a depth of 10 km under conditions of the amphibolite facies. Stage II, as constrained by metamorphic facies, is represented by zoisite amphibolites in mylonitized granite and the reaction of albite + 4 anorthite + 2H 2 O = pargasite + 2 zoisite + 2 quartz. Stage ...

Because marine deposits are distributed over large areas unevenly, mining companies utilize different methods to mine them. Some of these methods include shallowwater mining, deep sea operations involving high tech equipment and simple alluvial mining. Like open pit mining, the ore materials are usually transported offsite for further processing.
deposits (the chances of a mining claim developing into an operating mine are estimated to be around 1 in 10,0008) and the longterm monitoring and remediation that are often needed to avoid environmental contamination once a mine site has closed. The set of activities that describe the different stages of mining is called the mining sequence.
