摘要
本文提出了郯庐古岛弧—新裂谷式控矿构造系统及“等结性”金矿成矿集中区的新认识,将混合热液型金矿成矿机制概括为“递进叠加三合(和)式”成矿模式,并总结出“六位一体”的遥感地质综合找矿模式,为成矿预测提供了重要依据。文中提出了三类金矿预测区:①第一类,5个金矿成矿区;②第二类,5个金矿远景区;③第三类,4个找矿靶区。
Based on the systematic research on various types of gold deposits (including altered tec-tonite type, quartz vein type, veinlet -disseminated type and volcanic -subvolcanic type) along Tancheng-Lujiang fault and adjacent areas, eastern China, this paper summarizes the new achievments and thoughts on the regularity of regional metallogenesis and metallotect of gold with the application of remote sensing technique in gold geological survey, including in-tegration analysis of TM images data, comprehensive investigation and compiling a series of interpretation maps in scales of 1; SOOOOOto 1; 500000. The new achievments have been ac-cepted by relative geological Parties and organizations.
For the first, a new recognition is proposed in ore ?controlling structural system of Tancheng -Lujiang ancient island arc -new rift type and ' isorenge' gold mineralization con-centration areas. According to structure feature, the gold deposits in studied region are clas-sified into Jiaojia, Linglong, Jinshan and Sanahandao mineralization types. ' Progressive su-perposed triple type' metallogenic model is proposed for the gold deposits of mixed hy-drothermal type and remote -sensing geological comprehensive ore-searching model of 'Six in one' is summerized. Finally, three kinds of prospect areas are outlined, including five gold metallogenetic prospect arers, five gold mineralization prospect areas and four target of gold ore -searching.
