The results show that : 1 ) though the water environment of nanyisan is more muddy than others , algal can still grow ; 2 ) the composition and rock type of the algal limestone are complex , the main rock types include lettuce - like stromatolites , algal reef , digitate stromatolies , wave - like stromatolites and so on ; 3 ) the deposits of algal limestones were formed in low - energy peritidal to subtidal high - energy environment of lakeshore slopes , sliding under the action of gravity and some other factors and become slump mixosedimentite layers ; 4 ) the physical property of algal limestones layers is better than others ; 5 ) the genetic development of the sediment decides that the single deposit is small , distributive and thin - layed 結果表明,南翼山藻灰巖沉積水體環境相對渾濁,但藻類仍能生長;該區藻灰巖巖石組成及類型復雜,主要的藻灰巖巖石類型有包心菜狀疊層石、藻礁、指狀疊層石、水平波狀疊層石等;其主要為濱岸斜坡上低能潮上環境至高能潮下環境形成的沉積體,在重力等因素的作用下產生滑動或滑塌形成的微生物成因的滑塌混積巖;巖層物性好于其它巖層;藻灰巖層的成因決定了該地區單個沉積體規模小、分散、層薄。
