    Along the bedding the vein quartz was formed when the hydrothermal solution invaded into biotite-plagioclase gneiss granitic gneiss and amphibolite in the Hongan Group of the Dabie Mountains. The deposit length ranges from 80 m to 115 m the deposit width ranges from 60 m to 120 m and the deposit thickness ranges from 5 m to 18 m. In many gold ores the majority of the gold is located in cracks and the space between the quartz crystals. This happens because gold is often deposited in the last phases of vein formation. The result is that the first crushing step will yield the most gold with each pass after that yielding less.
