TEX86是一种新的重建古海水和古湖水表层水体温度(SST和LST)的指数。此指数不受表层水体的营养状况和盐度等参数的影响,能广泛应用于缺乏碳酸岩和有孔虫的沉积物的沉积相和早至白垩纪Aptian期地层的古温度重建。文章详细介绍了用于TEX86分析的类异戊二烯GDGTs的结构及其源生物,以及TEX86温标的原理、分析方法、应用和仍存在的问题。

[Abstract]
The TEX 86 (TetraEther indeX of tetraether consisting of 86 carbon atoms) is a new palaeothermometer of reconstructions for the past sea-surface temperatures (SST) and lake-surface temperatures (LST). It is confidently free from the effects of proxies changing on salinity and nutrient in the water-column,and then is used extensively on the palaeo-temperature explorations,especially,in the deposit basins lacking of carbonates and foraminifera and in the rocks earlier to the strata of Aptian Stage of Cretaceo...
