qiongzhong
解釋
瓊中-
The qiongzhong and danxian batholiths, as the largest early mesozoic syntectonic granite intrusions in hainan island, are mainly composed of porphyritic biotite two - feldspars granitoids, in which alkali - feldspar phenocrysts and dark minerals are foliated mostly in we - direction. the granites are of metaluminous i - type. major and trace elements show co - variations with sio2, suggesting the fractional crystallization of plagioclase, hornblende, apatite and ti - fe oxides in the evolution of the granites
花崗巖的主量元素和部分微量元素成分與sio _ 2呈良好的相關關系,顯示出明顯的斜長石、角閃石、磷灰石和ti - fe氧化物等的分離結晶作用,總體上它們與大陸島弧花崗巖的微量元素豐度和分佈特徵相似,系統地虧損ba 、 nb 、 sr 、 p和ti等元素。 -
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。
