1·Buried hills of high density crystalline rock appear as positive anomalies and even outcropping conglomerates will show higher values than surrounding claystones and marls.

被掩埋的高密度结晶岩山丘显示为正的重力异常。即使砾岩露头也会显示出比周围的泥岩和泥灰岩高的重力异常值。

2·Carbonate sedimentary facies include lime-mud flats and algal flats in littoral lake, grain banks in shallow lake, algal mounds in shallow lake and marls in semi-deep lake etc.

碳酸盐岩沉积相可划分为滨湖灰泥坪、滨湖藻坪、浅湖颗粒滩、浅湖藻丘以及半深湖泥灰岩相。
