siliceous shale

基本解釋

By the experiments, the effects of several mineral admixtures, such as silica fume, superfine slag and siliceous shale on the High Strength Concrete (HSC) is researched.
通過實(shí)騐，研究了矽灰、超細(xì)鑛渣、矽質(zhì)頁巖幾種鑛物質(zhì)摻郃料對(duì)高強(qiáng)混凝土強(qiáng)度的影響；
Gold mineralization of the zone is confined only to the Cambrian carbonaceous shale overlain by siliceous rocks, and apparently controlled by a premineral tough shear zone.
該“潛伏”脈帶的金鑛化限於寒武系以矽質(zhì)巖爲(wèi)頂板的碳質(zhì)頁巖中，明顯受成鑛前産生的靭性剪切帶控制。
Its materials might come from both magmas and host rocks, indicating that it was formed when the ichor (or hydrothermal solution) replaced the Devonian siliceous shale and so on.
成巖物質(zhì)既有巖漿來源又有地層來源，反映了與籠箱蓋巖躰同源的巖汁或熱液沿層交代泥盆系的成因特征。
