摘要
根据磁场特征和磁性基岩等深线图,作者推断出秦豫地区基底断裂51条,隐伏岩体56个,并对断裂系统的展布规律和隐伏岩体的分布特点进行了分析。认为,以推断的栾商、襄广两条深大断裂为界,全区自北向南可划分为华北准地台、秦岭地槽和扬子准地台3个Ⅰ级构造单元。在上述工作的基础上,预测大河屯、郭滩、新野和天门—沙洋4处为最有希望的含油气远景区;陈官营等7处为有希望的含油气远景区;鼓桥等9处为可能的含油气远景区。
The high-precision aeromagnetic survey on the scale of 1 : 106 was carried out by CCGSGS in 1984 in Qin- Yu region . On the basis of feature of the magnetic anomalies and the isodepth map of the magnetic basement rock , the 51 fundamental faults and the 56 blind plutons were inferred in the region . And being bounded by two deduced deep faults > Luan
- shang and Xiangguang , the whole region is divided into 31 - grade tectonic units from the north to the south , namely Huabei metaplatform , Qinling geosyncline and Yangzi metaplatform . It is pointed out that the Dahetun ,Guotan ,Xinye and Tianmen -Shayang are the most prospective in oil and gas , the 7 areas ,such as Chenguanying and so on ,are more prospective , and another 9 areas , such as Guqiao and others might be prospetive in oil and gas .
