以我国首次试验的航空重力数据为基础,通过局部重力异常的突出方法处理和反演拟合,结合航磁、地震、钻井等资料,按照引起局部异常的地质体性质,将研究区的局部重力异常划分为6类,即与基岩凸起有关的局部异常、与基岩凹陷有关的局部异常、与侵入岩有关的局部异常、与喷出岩有关的局部异常、与中酸性岩浆岩中老地层有关的局部异常、与深部地幔柱有关的局部异常。每类局部异常又可根据具体的地质体属性划分为若干种局部异常,并构成某种矿产资源的反映。其中,基岩凸起异常、基岩凹陷异常、岩浆岩体异常分别构成油气田、煤田、金属矿床的重要找矿标志。正确认识局部重力异常及其成因,是航空重力地质资源调查的目标之一,具有重要的找矿意义。 Based on the data of aeronautical gravity data from the first experiment in our country, the local gravitation of the study area is processed and retrieved by the prominent methods of local gravity anomaly, according to the data of aeromagnetic, seismic, drilling and so on. The anomalies are divided into six types, namely, the local anomalies related to the bedrock bump, local anomalies related to bedrock depression, local anomalies associated with intrusive rocks, and local anomalies associated with extrusive rocks, Local anomalies associated with the strata, and local anomalies associated with deep mantle plumes. Each type of local anomaly can be divided into several kinds of local anomalies according to the specific geologic body attributes and constitute a reflection of some kind of mineral resources. Among them, the anomaly of bedrock, anomalous bedrock anomaly, and anomaly of magmatic rock constitute the important prospecting marks of oil and gas fields, coal fields and metallogenic deposits respectively. A correct understanding of the local gravity anomalies and their causes is one of the targets of the investigation of the airborne gravity geology resources and has important prospecting significance.
