Both the a-axis and ab-plane dip towards the downstream , the dip angles of the a-axis are low and concentrated, being 7—8°,the ab-plane dips at 7～21°, and the a-axis has more preferred dip of fabrics than the ab-plane; the peak of the grain-size frequency distribution curve of deposits in the Lushan area is in the range of 4 and 5 φ;The quartz sand grains are subangular and have well-developed conchoidal fractures, parallel striatio ns, upturned cleavage flakes,"V"-shaped holes and siliceous deposits.

摘 要：庐山第四纪泥砾沉积物的砾石组构特征表明，砾石岩性与山体基岩基本一致，砾石的等体积球径较小，加权平均砾径较中值砾径大，分选系数大于1，分选性差，φ值相对较小，平均为0.66，F值相对较大，在2左右，F/φ比值介于2.75～4.75，ρ值集中且较小，为22.75%～37.75%，砾石以棱角、次棱角状为主，磨圆较差；a轴和ab面都倾向沟谷下游，a轴倾角集中且较小，为7～8°，ab面倾角为7～21°，a轴较ab面具有更为优势的组构倾向；沉积物粒度频率曲线在4～5Φ范围内表现为峰；石英砂颗粒为次棱角状，贝壳状断口发育，具平行擦痕、上翻解理片、V形坑和硅质沉淀。
