The petrographic study of the piedmont potassic belt indicates that the rocks in the piedmont potassic belt of Hadamengou gold deposit are mainly composed of potassic feldspar, plagioclase and quartz, which are distributed in a scattered form, and the rock fragmentation structure is widely developed. The study of element geochemistry and other aspects shows that the rocks in the piedown potassified zone are mainly composed of potassium feldspar, plagioclase and quartz, followed by a small amount of sericite, epidote and kaolin. The main elements mainly contain high K 2 O and low Na 2 O, and the K 2 O/Na 2 O ratio is higher than 2, all of which belong to the hyperpotassium series rocks.
