盐湖

ABSTRACT Dunaliella, a single-celled green algae classified to Chlorophyceae of Chlorophyta, distributes throughout salt lakes and sea over the world. Dunaliella inhabits itself in the environment rich in Na〓 and Cl〓.

杜氏藻广泛分布于世界各地的盐湖和海水中，是一种单细胞绿藻，归属于绿藻纲、绿藻门。

According to the statistics of the content of methyldibenzothiophenes in 112 oil samples from China, the conter of methyldibenzothiophenes in marine oil is more than that in terrestrial oil if there is no TSR in oil.

根据对中国含油气盆地112个原油样品中似甲基二苯并噻吩含量统计发现，当原油无TSR作用时，海相原油的似甲基二苯并噻吩含量要大于陆相原油；陆相原油中，盐湖相原油的似甲基二苯并噻吩含量又大于淡水湖相。

It is concluded that the variation of S,C,O isotopes and clay minerals is correlatable with the change of sedimentary environment,and that the sedimentary environment of Qianjiang Formation in Qianjiang Depression is an obstructed saline lake of inner land.

封闭盐湖中原生碳酸盐岩和粘土矿物的形成与湖泊水体的化学性质密切相关，从湖泊的低水位到高水位水体化学性质在一定范围内依次变化。

In the Early Cambrian, the Tarim area was mainly a carbornate platform, in which there were penebanks, dolomitic flat, and gypsum-halite lake.

在早寒武世，塔里木地区是一个碳酸盐岩台地，其中散布着准滩、云坪和膏盐湖。

From the great inland seato the distant Wasatch Mountains there was no name better known than that ofJohn Ferrier.

从盐湖这个内陆海起，一直到遥远的瓦撒起山区为止，在这个地区以内，再没有比约翰·费瑞厄的声名更大的了。

Glauberite is a main ore mineral in sodium sulfate deposits widely distributed in modern salt lakes and Meso- and Cenozoic salt-bearing series.

钙芒硝是硫酸钠矿床的主要矿石矿物。它在现代盐湖，尤其是在中新生代含盐系有广泛的产出。

The origin of glauberite attributes to various processes, including(1) direct crysllization from sulphate solution;(2) substitution of glauberite for gypsum;(3) transformation from hydrous glauberite; and(4) ion exchange between sodium sulfate and calcium-bearing mud.

钙芒硝的成因可归纳为：(1)直接从硫酸盐溶液晶出；(2)交代石膏成因；(3)从卤水中先沉积水钙芒硝后脱水变为钙芒硝；(4)硫酸钠溶液与含钙淤泥之间发生离子交换而生成。与菱镁矿紧密共生产出于海相地层之钙芒硝很可能形成于潮坪盐湖环境。

Taking for example the salt rhythms of the Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin (which is a typical Paleogene saline lacustrine basin in eastern China), through a detailed study on cores, the authors have determined for the first time the Ⅳ-order salt rhythm based on Ⅰ-,Ⅱ-and Ⅲ-order salt rhythms which were determined previously and got to know that the sedimentary process following the sequence of desalinizing→salinizing and crystallization of salt minerals from halite rock→(mud-bearing) glauberite rock→dolomite-bearing mudstone (mud-bearing doloston)→mudstone→doloston→glauberite rock→halite rock. The authors also analyzed the Ⅳ-order salt rhythm and the correspondence between its sedimentary records and the fluctuation of the palaeosalinity of waters and the short-scale (0.05~1.0 ka duration) change of dry-moist palaeoclimate.

本文以我国东部独具特色的古近纪古盐湖盆地－江汉盆地的潜江凹陷潜江组盐韵律为例，通过对王平1、王云10-6、王80-2等3口井连续取心段的精细研究，在前人划分Ⅰ、Ⅱ、Ⅲ级盐韵律的基础上，首次划分出组成含盐层系基础韵律单元－Ⅳ级盐韵律，弄清了它的沉积过程基本遵循从石盐岩→钙芒硝岩→含白云石泥岩→泥岩→白云岩→钙芒硝岩→石盐岩的淡化－咸化序列和盐类矿物的析出顺序；解析了Ⅳ级盐韵律及其沉积组合记录与水体古盐度波动和短尺度(0.05~1.0 ka)古气候干湿变化之间的对应关系。

The nautre of ester bond and sedimentary medium condition control the distribution pattern of organic acid ester in strong reductional environment and water-washed oxidized crude oils. The former features higher contents both of 9, 11-Octadecadienoic acid, methyl ester and Hexadecanoic acid, showing the non-reversible hydrolysis reaction of ester bond in condition of basicity; the later features higher contents of Hexadecanoic acid and Octadeanoic acid, and lower contents of nonsaturated and side-chain acid ester, indicating the reversible hydrolysis reaction of ester bond in acid condition.

酯键的化学性质和沉积环境中介质条件，决定了强还原咸水盐湖相和淡水湖沼相经水洗氧化次生变化的原油有机酸酯的分布特征，前者9，11-十八二烯酸甲酯与正十六烷酸为主，反映酯键在碱性条件的不可逆水解过程，后者以正十六烷酸和正十八烷酸为主，烯酸和支链酸很少，反映酯键的酸性条件的可逆性水解，烯酸经氧化向正十八烷酸，正十六烷酸转化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
