qiongzhong 中文意思是什麼

qiongzhong 解釋
瓊中
  1. 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。
  2. 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。
  3. 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。
  4. Observation on the effect of naphthoquine phosphate on the control of malaria in qiongzhong county, hainan province

    海南省瓊中縣高瘧區應用磷酸萘酚喹控制瘧疾的效果
  5. The direct evidence about tectonic boundary between sanya terrain and qiongzhong terrain

    三亞地體與瓊中地體構造邊界的直接證據
  6. 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。
