在贞丰县城附近,早三叠世印度期地层发生相变,相变带两侧分别为夜郎组第二段灰岩和安顺组第一段下亚段白云岩。本文介绍了该相变带的地质特征,分析其形成的缓坡型碳酸盐环境,并指出该相变带是贵州早三叠世最早的岩相变化带,进而探讨了它的地质意义。
在貞豐縣城附近,早三疊世印度期地層髮生相變,相變帶兩側分彆為夜郎組第二段灰巖和安順組第一段下亞段白雲巖。本文介紹瞭該相變帶的地質特徵,分析其形成的緩坡型碳痠鹽環境,併指齣該相變帶是貴州早三疊世最早的巖相變化帶,進而探討瞭它的地質意義。

Near the Zhijin county town,the phase changes in the Induan age of early Cambrian,the two sides of the transformation band are limestone in the second section of Yelang formation and dolomite in the first section of Anshun formation.In this paper,the geologic characteristic of this transformation band is introduced,it analysis the gentle slope-pattern carbonate environment and points out this transformation band is the earliest of early Cambrian in Guizhou,its geologic significance is discussed.
