red quartz cement

Jul 01 2019 · Furthermore for the samples with similar amounts of quartz cement the porosity decreases with increasing depth and the reduction rate gradually increases as the samples shift from high to low quartz cement content implying that quartz cement plays an important role in the partial prevention of porosity for tight sandstones Fig 10 d
