The natural sulfur deposit in a certain place in Xinjiang is a medium-sized deposit, and the geological characteristics of the deposit are summarized as follows. First, mining geological overview The mining area is located in the northern foot of Kunlun Mountains, the southwestern margin of the Tarim Basin. Over 75% of the area is covered by loose quarries of the Quaternary, with only a few sporadic outcrops. The strata have been formed from the oldest to the new (Figure 1).
