The zircon shrimp u - pb dating results suggest that the qiongzhong and danxian granites were emplaced at 237 3 ma and 186 3 ma , respectively , which argued against the previous thoughts that all the foliated granites with orientated structure in hainan island formed duing the hercynian - indosinian episode
高精度shrimp锆石u - pb定年显示琼中岩基形成于印支期( 237 3ma ) ，而儋县岩基形成于燕山早期( 186 3ma ) ，修正了前人将海南岛具有定向构造的变形花岗岩等同于海西?印支期花岗岩的认识。
The qiongzhong and danxian granites are belong to the kcg - type ( k - rich calc - alkaline ) granitoids according to the tectonic nomenclature by barbarin ( 1999 ) . these foliated kcg - type granites with original orientated structure are the results generated in a changing geodynamic orogenic environment with alternating compressional to extensional stress field . this suggests that hainan island has been a part of south china since latest permian , and been major in extrusion environment of the tethys tectonic system
根据barbarin ( 1999 )分类，琼中和儋县岩基花岗岩属于高k及含钾长石斑晶的钙碱性花岗岩，同时它们具有原生定向构造，是挤压?松弛?挤压的构造演化过程的产物，表明海南岛从二叠纪末期开始已经是华南大陆的一部分，主要受到了特提斯构造域的影响。
