| 摘 要： | 以江苏南部1：20万重力资料为基础，通过对区内岩石及地层密度特征的归纳与分析，对区内重力场形成的地质因素作了讨论。对区内重力场进行了分类、分区及地质解释。通过进一步对区内重力资料的数据处理，一方面对区内莫霍面及印支一燕山面的埋深、形态特征及其地质意义作了讨论，另一方面对区内断裂构造及变质基底分布格局也作了推断解释。

| Abstract: | Based on gravity data in a scale of 1 ： 200,000 and through analyses of the properties of rocks and strata density in the study area, the author discussed the geological factors formed by regional gravity field. In addition, the author divided the types, zones and conducted geological explanations for the gravity field in the study area. Through gravity data processing, the author discussed Moho surface and the burial, morphological characteristic and geological significance of Indosinian-Yanshan face, made inferred interpretation for the fracture structures and metamorphosed basement. |
