All geothermal water samples show high concentration of F, Si, Sr and Fe.Concentration of Fe, Si, and Sr ions is mainly controlled by solubility of fluorite, quartz andchalcedony, and celestite, respectively.

其中，F离子浓度主要受控于萤石的溶解；硅含量主要受控于石英和玉髓矿物的溶解；锶离子浓度主要受控于天青石矿物的溶解。

The study of fluid inclusions in sphalerites and associated gangue minerals (quartz, celestite, calcite and gypsum) shows that homogenization temperatures cluster around 110-150℃, with salinities of 1.6-18.0 wt% NaCl equivalent. The fluid temperature increased with the decrease in salinities during the main ore stages, and there is also a systematic westward decrease in temperature and increase in salinity in the Jinding ore district.

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。
