Using established dynamics model, the author has explained the genesis of numerous dolichos lablab limestone and siliceous limestone in the two growing stages of southern China, i.e. carbonates developing stages (Donggangling stage of middle Devonian and Changxing stage of late Permian). Because numerous carbonate rocks have been produced on the platform, at the same time, it is one of ignored material sources that numerous carbonate lime-mud have been transported from platform to basin.

运用所建立的动力学模型对中国南方两个重要的成礁期，即生物碳酸盐发育期(中泥盆世东岗岭和晚二叠世长兴期)，台盆内大量扁豆状灰岩和硅质灰岩的成因做了解释，因为台地上大量碳酸盐生产的同时，由台地向盆地输送的大量碳酸盐灰泥是盆地内的一个不可忽略的物质来源。

This paper discusses the research carried out on the Lake Sugan, in the northern margin of Chaidam Basin. The climate and environmental changes in Lake Sugan drainage area over the past 2670 years were studied using the varve dating of the well preserved lamination sediments in core SG03I taken from the center of Lake Sugan, the study of varve formation in modern lake system and modern process study of carbonate and oxygen isotopes of the water within the drainage area, and according to the main index of the stable isotopes of carbonate sediments synthesized other index analysis.

本文以柴达木盆地北缘苏干湖为研究对象，通过对湖泊中心位置SG03I孔保存完好的纹泥沉积物岩芯进行年代学研究，对湖泊现代沉积过程及碳酸盐、流域水体同位素进行现代过程研究，以沉积碳酸盐稳定同位素指标为主，结合其它代用指标的综合分析，探讨苏干湖流域近2670年来的气候与环境变化，综合区域其它记录对苏干湖流域晚全新世气候变化的驱动机制进行探讨，获得如下认识：1、柴达木盆地北缘苏干湖若干钻孔岩芯发现，水深大于3.0m的沉积物均具有裸眼可分辩的由深色层和浅色层组成的纹层层理。

The main sedimentary facies types include shoal facies of platform margin, organic reef facies of platform margin, platform evaporate facies, open-platform facies, restricted platform facies and carbonate platform ramp facies, and the front three types of facies are the uppermost facies belt. The main sedimentary microfacies types include subordinate organisms dolomite microfacies, sparry grain(biogenic debris, sand cutting, alga chippings and so on) dolomite microfacies, detention gravel debris dolomite microfacies, boundstone microfacies, non-lamina dolomite mudstone microfacies, lamina dolomite mudstone microfacies, lamina lime mudstone microfacies, sparry grainstone microfacies and testaceous chippings limestone microfacies, and the front three types of microfacies are the uppermost microfacies type.

该区长兴组主要的沉积相类型有台地边缘浅滩相、台地边缘生物礁相、开阔台地相、局限台地相、台地蒸发岩相和碳酸盐台地缓坡相六个相带，主要的微相类型有生物粘结云岩微相、亮晶颗粒云岩微相、滞留角砾云岩微相、纹层纯云泥岩微相、非纹层纯云泥岩微相、生物粘结灰岩微相、纹层纯灰泥岩微相、亮晶颗粒灰岩微相和介屑灰岩微相九种微相类型。

As the ferroan sparry carbonate cements were formed later and the sandstone reservoir was on the whole not subjected to any other constructive diagenesis, the development of carbonate cements must have played an apparent controlling effect on reservoir characteristics.

由于含铁碳酸盐胶结物形成时代晚而且储层未受到其他建设性成岩作用的明显改造，晚期碳酸盐胶结物含量和面孔率呈互相补偿的关系，表明了晚期碳酸盐胶结物对储层物性的破坏作用。

In Southwest China, carbonate rocks are mainly distributed along the NE-extending tectonically upheavedzone, deeply impacted by geological background.

中国西南岩溶石山区岩溶发育的地质历史背景，决定其碳酸盐岩主要分布于NE向的构造隆起带上。

In Chinese Palaeozoic era, many multiorigin prototype basins were overlapped and composite, paleokarst was welldeveloped because of multiperiod tectonic movement, largethickness and widely distributed carbonate rocks of sea facies.

中国古生代具有多时代、多类型原型盆地叠加复合的特点，海相碳酸盐岩分布广、厚度大，受多期构造运动等因素的控制和影响，古岩溶十分发育。

Microspar structures,so far,are enigmatic of Precambrian,and generation interpretation is still to go.

由于缺乏现代相似沉积物，臼齿构造碳酸盐岩的成因还是一个谜，需要进一步研究和探索。
