Story summary

Chinese geologists identified the Xiaohuaguo high-purity quartz deposit near Shiyan, Hubei.
Purified quartz from the deposit exceeds 99.9% silica purity.
Its particle size and morphology closely match Unimin’s IOTA-CG quartz sand and Spruce Pine mine quartz.
Researchers from China University of Geosciences, Wuhan Centre of China Geological Survey and Hubei Geological Bureau led the study.
The study appeared last month in the peer-reviewed journal Earth Science.
