cloud

The precipitation and cloud water in spring at the top of Lushan was acidified seriously, the pH value of all samples was below 5.

庐山春季高山降水和云雾水均已严重酸化,所采样品的PH值全部小于5。

The composition of cloud water was higher than precipitation; the composition of solid precipitation was higher than liquid precipitation by 2￣6times; but the pH val.

２６，降水中主要酸性物质是硫酸，而硝酸则占次要地位；云雾水组成高于降水，且酸度强于降水；对不同相态降水的比较表明，固相降水组成比雨水高２～６倍，但ｐＨ值比雨水高０。

The dolomitized patches were produced by early diagenetic dolomitization which preferentially began within Thalassinoides burrows and spread into the surrounding lime mud.

云斑状构造是早期白云石交代作用优先沿着痕迹化石Ｔｈａｌａｓｉｎｏｉｄｅｓ潜穴进行，然后向围岩扩散而形成的。
