| 摘 要： | 从相分析着手,重点剖析京山、崇阳两条岩相剖面,系统地研究了岩石、古生物、地球化学组分及分布规律。在此基础上提出了中扬子二叠系碳酸盐岩岩相模式。二叠系碳酸盐岩属台地碳酸盐岩岩相,包括潮坪、局限台地、台地浅滩、开阔台地A、开阔台地B、边缘浅滩、斜坡等七个次级相。该模式较合理地解释了中扬子二叠系碳酸盐岩的发育规律,并对硅质岩、白云岩的成因提出了新认识。

| Abstract: | Starting with the fades analysis and emphatically dissecting two field sections of Jinshan and Chongyang On the Middle Yangtze Permian Carbonate Platform,a carbonate facies model has been established based on systemically studying its rock,palaeobiology and geochemistry.The facies model includes seven subfacies,i.e.tidal flat,restricted platform,platform shoal;broad platform A,B;edge shoal and platform slope.The model more reasonably explain the Permian carbonate rock development and puts forward new viewpoints on the forming of silicalite and dolomitite,and can be used as a reference criterion in future facies analysis work. |
