样子哨盆地基底为龙岗地块,盖层以晚元古代地层、古生代地层为主。基底构造变形以韧塑性变形和塑性纵弯柔流褶皱及固态流变剪切变形为主,发生片理、片麻理、褶皱及条带状构造。盖层经历多次挤压隆升和拉张断陷运动,屡次遭受海侵—海退,沉积了典型的地台型沉积建造。后经断块运动,改造或继承先期断裂,形成盆地—山岭式构造。
樣子哨盆地基底為龍崗地塊,蓋層以晚元古代地層、古生代地層為主。基底構造變形以韌塑性變形和塑性縱彎柔流褶皺及固態流變剪切變形為主,髮生片理、片痳理、褶皺及條帶狀構造。蓋層經歷多次擠壓隆升和拉張斷陷運動,屢次遭受海侵—海退,沉積瞭典型的地檯型沉積建造。後經斷塊運動,改造或繼承先期斷裂,形成盆地—山嶺式構造。

Yangzishao Basin basement is Longgang land mass,cover rock is mainly Late Proterozoic and Paleozoic strata.The basal tectonic deformation is mainly tough plastic deformation and plastic vertical soft curved flow folds and solid rheological shear deformation,occurred schistosity,gneissosity folds and banded structure.The cover rock experienced many compression uplift and extensional rift motion,repeatedly suffered transgressive-regressive,and deposited a typical platform sedimentary formation.After the block movement,transformed or inherited pre-fractures formatted the Basin – mountain structure.
