綜合利用巖心、普通薄片、全巖和黏土礦物X射線衍射、碳氧同位素等資料,對珠江口盆地西部珠江組二段Ⅰ油組海相砂巖地層鈣質(zhì)隔層的巖性和礦物結(jié)構(gòu)特征、成因模式及其分布規(guī)律進行系統(tǒng)研究。研究區(qū)鈣質(zhì)隔層巖性主要為含陸源碎屑生屑灰?guī)r和少量細粒鈣質(zhì)石英砂巖。在此基礎上建立了兩種鈣質(zhì)隔層的成因模式:蒸發(fā)作用海水成因和淺埋藏淡水成因。蒸發(fā)作用海水成因的鈣質(zhì)隔層在前濱亞相發(fā)育,主要發(fā)育在1-1巖層組和1-3巖層組頂部。淺埋藏淡水成因的鈣質(zhì)隔層在后濱亞相發(fā)育,主要發(fā)育在1-2巖層組。
