英文
volcanic accident-
By comparing i8o curve with annual growth rate and grey level curve in the stalagmite during the same period, the author brings forward that that climate in shennongjia region mostly embodies matching modes of warm / wet, cold / dry over the past 2000 years, but temperature was out of harmony with precipitation in the course of climate transforming, which shows that shennongjia climate embodies matching modes of cold / wet, warm / dry at part period of time
近2000年中17次太陽活動和1400aad以來29次火山活動對氣候變化影響的印跡在石筍氧同位素中都有明顯的記錄，表明氣候事件與太陽活動、火山活動有較好的相關性。石筍各代用指標譜分析顯示126a 、 100a 、 81a 、 60a 、 40a 、 22a 、 11a等周期成分，也進一步支持了太陽活動對季風區短尺度氣候變化的驅動作用。We deduce that it is a relic old crust that was brought upwards during the formation of neo - tethyan ophiolite. the step heating 40ar - ' 9ar spectra show that during 100ma, luobusha ophiolite suffered intensely alternation, which affected distinctly the k - ar system ; during 771ma some basalt formed in the country rock of xiubugabu ophiolite ; during 55ma, the pillow basalt of rikangba ophiolite affected by a strong thermal event ; all the variety of ages illustrates possible impacts of the subduction - collision between india and eurasia. through dissecting mainly the gabbro of luobusa ophiolite and studying the 40ar / 39ar
~ （ 40 ） ar ~ （ 39 ） ar階段升溫年齡圖譜顯示， 100ma左右羅布莎巖體經歷了較強的後期蝕變作用，對其k ? ar體系造成明顯影響； 77 1ma休古嘎布巖體圍巖中形成玄武質火山集塊巖； 55ma日康巴巖體巖石枕狀玄武巖受到較強熱事件影響；這些~ （ 40 ） ar - ~ （ 39 ） ar年齡上的變化顯示了印度板塊與歐亞板塊俯沖?碰撞對該區的強烈影響。After the volcanic eruption of multi - phrase cycle - deformation, filling of basin, crustal uplifting event being studied, this dissertation tries constructing the different degree rhythm of magma activity corresponding with crust - mantle dynamic system, studying the crust - mantle deep processes. based on the studies on the characteristics of volcanic rhythm, igneous rocks assemblages, temporal and spatial distribution of igneous rocks, tectonic deformation, the author has util ized the methods of petrology, geochemistry, isotopic geology et al. to do research on the above - mentioned geological problems
通過多次幕式火山噴發-構造變形-盆地充填-地殼隆升事件序列的釐定，從火山活動節律特徵、火成巖構造組合類型、時空分佈及其演化和構造變形的歷史記錄，利用巖石學、地球化學、同位素地質學等方法，反演深部過程與淺部響應等來闡明造山過程，建立與不同級別巖漿活動節律對應的殼幔動力學系統，追索殼幔深部過程，已成為當今地球動力學研究的前沿課題之一。Finding a reasonable candidate for an impact crater marked a turning point in the search for the causes of extreme climate perturbations and mass extinctions ? away from earthly sources such as volcanism and toward a singular, catastrophic event
針對地球上氣候大變動、生物大滅絕的研究，從此發生了重大轉折，因為學者找到了一個合理的隕石撞擊點，就不再只是著眼于地球內部的肇因，例如火山活動，他們開始認為整個事件源自非比尋常的大災變。分享友人
