摘要
样子哨盆地位于龙岗隆起北西部,具有多时代叠加沉积,多期次构造演化特征。地层主要由上元古界、古生界、中生界、新生界组成,沉积中心由北东向南西转移;区内褶皱构造发育,上元古界褶皱构造以全形紧密褶皱为主,古生界褶皱构造以全开阔线形复式褶皱为主;盆地找矿前景较好,在南西部具备形成矽卡岩型多金属矿的地质条件,南东部沿盆缘断裂具备形成浅成低温热液型金矿的地质条件,盆地中部中生界煤系地层也较发育。
The Yangzishao Basin is located in the north west of the Longgang uplift, which has multiperiodic superimposed deposit, multiphase tectonic evolution characteristics. Formation is mainly composed of the upper Proterozoic, Paleozoic, Mesozoic and Cenozoic, sedimentary center transfers from the north east to south west; The folding structure development in the study area, the upper Proterozoic fold structure is given priority to full close fold, Paleozoic fold structure is given priority to with full open linear double fold; the prospecting prospect of Basin is good, the southwestern part has the geological conditions for forming skarn type polymetallic mineralization, the southeastern part along the basin edge fracture has geological conditions for forming shallow low temperature hydrothermal type gold deposits, the central part of Basin,and the Mesozoic strata is also development.
