摘要
Laobaojia diatomite mine is located in the western part of the Laobaojia Village, Changbai County of Jilin Province, occurs in the Tumenzi Formation. Known mineral thickness is 8.76 ~ 18.20 m, with an average grade (SiO2) 70.96%, has capacity of 182 600 tons of ore control. Through the analysis of ore-forming environment and the metallogenic regulations, it is considered that the mine is located in a favorable position of diatomite ore, further investigation the possibility of greatly expanding the size of ore body.
