中文拼音 [dānxiàn]-
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鋯石u - pb定年顯示瓊中巖基形成於印支期（ 237 3ma ） ，而儋縣巖基形成於燕山早期（ 186 3ma ） ，修正了前人將海南島具有定向構造的變形花崗巖等同於海西?印支期花崗巖的認識。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
根據barbarin （ 1999 ）分類，瓊中和儋縣巖基花崗巖屬于高k及含鉀長石斑晶的鈣堿性花崗巖，同時它們具有原生定向構造，是擠壓?鬆弛?擠壓的構造演化過程的產物，表明海南島從二疊紀末期開始已經是華南大陸的一部分，主要受到了特提斯構造域的影響。The qiongzhong granite should have been formed at orogenic relaxing stage after the peak of indosinian orogeny, and the danxian granite were formed at the latest orogenic phase
瓊中巖基可能形成於「印支期」碰撞造山運動峰期后的鬆弛階段，而儋縣巖基則可能形成於造山運動的結束階段。
