According to the types of rock density and magnetism of magmatite , with separation , continuation , derivation , and false color encoding between gravity anomaly and magnetic anomaly as well as a composite process of their attributive information , the magmatite belts reflected by both gravity anomaly and magnetic anomaly can be divided into two belts and seven group sections based on their positions in the tectonic unit , the magma series characteristics , and the time - space relationship with the ore belt 摘要根據(jù)不同類型巖漿巖的巖石密度、磁性的不同,通過重磁異常分離、延拓、求導(dǎo)、異常的彩色編碼及重、磁特徵信息的復(fù)合處理等,按重磁反映的巖漿巖帶所處的構(gòu)造單元部位、巖漿系列特徵以及與礦帶的時(shí)空關(guān)系,將秦嶺造山帶劃分為2帶和7個(gè)群段。
