| 摘 要： | 察尔汗盐湖，除其边缘分布有１０个卤水湖或季节性卤水湖外，其余均为盐壳所覆盖。盐壳划分为４种不同类型：①龟裂状盐壳；②尖棱状盐壳；③疙瘩状盐壳；④平坦状盐壳。盐壳主要以卤水湖为中心向外，由新至老呈环带或半环带状分布，构成了察尔汗盐湖独特的微地貌景观，并为研究湖区古气候及盐湖演化提供了重要信息。

| Abstract: | Widely outcroping near the Shimen realgar deposit, Hunan, and derived from siliceous sinter induced by hot springs, silicalite has trace elements similar with those of the ores and the modern hot spring sediments. The ore forming solutions also are comparable in abundances of Na +, Ca 2 +, Cl -, HCO 3 - and SO 4 2- to those of the spring sediments. Studies of petrology, petrologic chemistry, trace elements, rare earth elements and isotopes give abundant eveidence that the silicalite should owe its origination to hot water deposition, with a source of siliceous materials from the underlying or deep rocks. |
