Quartz sandstoneIncluding structure, structure, quartz feldspar mica content, etc.
The main output of three layers: three Xujiahe formation at the top of the lower Jurassic zhenzhuchong formation and middle lower Jurassic Ziliujing formation at the bottom. The chemical composition of the ore is 97.30 97.32% alumina: silica, 0.97 ~ 1.04%, 0.62 ~ 0.67% of iron oxide, calcium oxide 0.034 - 0.043%, 0.003% p2o5. The water absorption rate is 1.01 to 2.55%, and the refractoriness is between 1716 - 1723 DEG C.
Sandstone in sedimentary clastic rocks of quartz sandstone, a kind of quartz (quartz sandstone, quartzite, quartz sand, quartz vein). Glass and metallurgical auxiliary raw materials.
Weathering is fresh is gray, gray white, sandy structure, massive structure. The main mineral composition is quartz.Quartz: Gray - colorless transparent, granular, particle size of 0.1-0.25mm, accounting for about 97% of the total content.The cement is mainly siliceous, and the base of the detrital minerals is (void) cementation.
