＜正＞ This paper deals with the evolution of carbonate rocks and associated strata-bound depositsof various geological times in China. Distributions of the carbonate rocks are not very homo-geneous in time and space. Temporally, they are less common in both Archaean and Meso-Cainozoic strata, but more abundant in Palaeozoic and Proterozoic strata; spacially, they aremore abundant in the East Platform, but less in the West Folding Zone. They were depositedmainly in the sedimentary environments with shallow water. The Archaean carbonate rockswere formed by chemical processes, the Proterozoic carbonate rocks composed mainly of dolo-mites were deposited by algal activity, and the Palaeozoic and some Meso-Cainozoic carbonaterocks, in which limestones were predominant over dolomites, were formed by chemical and bio-chemical processes. After the Proterozoic era bioherms and banks were initiated. Many strata-bound deposits are found to associate with carbonate rocks in China,most of which were formed from the reformation caused by Hercynian and Yenshanian oro-genies.
