通过研究金牙金矿作用的生物成矿系统内容为：在早、中三叠世罗甸—丹池裂谷盆地接受沉积时，生物对金等成矿物质就存在预富集作用；在成岩过程中，生物转化为有机质及有机热流体，对生物及沉积物中的金等成矿物质存在溶解、萃取、富集作用；在盆地压实成岩作用中，盆地中有机热流体向凌云水下碳酸盐台地运移，并在台地边缘外凸部位集中，此过程流体携带大量成矿物质，对金等成矿物质存在迁移集中作用；深部热流上侵使有机流体发生降解和释放金的热作用、形成高含金的有机热液，含金热液上移在构造通道中沉积并被有机碳再次吸附，最终形成金矿床，对金存在成矿作用。

Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.

目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式，一是运用同位素地质温度计原理，利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系，对湖泊古水温做定量研究；二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温；三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。

Results show that palaeo-water depths decreased from middle submember sedimentary period to lower submember sedimentary period and to upper submember sedimentary period in Dongying Sag.

Between 2,500 yr BP and 1,800 yr BP. This was a neo-glacial age with a cold snap. The ice-cap on the King George Island and Ardley Island advanced. Iso -static adjustment lowered the palaeo -first terrace at the edge of Ardley Island under the high tide sea level. This made the rookeries around Y2 lake disappear and Y2 lake changed into a lagoon. The fact of Y2 lake under the sea level was coincident with the radiocarbon age (2180±95 yr BP) of the modern third raised beach terrace with 14m-height above the sea level near Yin ' Ou lake in the Fildes Peninsula.

第二阶段，距今1，800至2，500年，该时期气候骤冷，温度急降，该时期乔治王岛的冰帽有所扩张，同时在阿德雷岛上也出现小规模冰进，由于&地壳均衡&补偿使得该岛边缘古一级阶地处于高潮海平面之下，Y2湖周围的企鹅聚居地消失，该时期 Y2湖沉积表现为泻湖相沉积，与 Y2湖相邻的 Fildes 半岛燕鸥湖边海拔14米的上升海滩的三级阶地14 C 年龄为2180±95yr。

On the basis of the researching of facies、 petrology、 cathodoluminescence analysis, this paper concludes that the terrigenous clastics in Pingyipu Formation were mostly originated from Motianling palaeo-peninsula lied to its north, and sands in distributary channels、 braidedriver in estuaries、 deltas and in littoral zone in hybrids could be derived from Middle-Sichuan Palaeoland with Peng-Guan Highland.

对早中泥盆世浑水陆源碎屑沉积及混合沉积的沉积相、岩石学、阴极发光等研究分析，作者推测，该区陆源碎屑主要来自北边的摩天岭古半岛，而分流河道、辫状河充填及混积滨岸砂则可能以川中古陆和彭灌高地为主要源区。这一点与过去通常认为的主要来自彭灌岛和轿子顶古岛差别较大。
