In this paper, the authors used such geophysical exploration methods as the high - precision geomagnetic method, the resistivity profiling method and the induced polarization method to synthetically study the exhausted areas of the archean sedimentary metamorphic iron mines in eastern hebei, built an effective geophysical exploration combination model for the exhausted areas, and summarized the serviceability and validity of various geophysical exploration methods in the exploration of exhausted areas under different geological settings
摘要應用高精度磁法、電阻率剖面法、激發化法等常規地球物理勘查方法對冀東地區太古宙沉積變質鐵礦采空區進行綜合研究,建立冀東鐵礦采空區有效的地球物理勘查組合模型,總結不同地質環境條件下各種地球物理勘查方法在冀東鐵礦采空區勘探中的適用性和有效性。Through measuring and comparing the magnetic susceptibility dates of loess profile in guanzhong plain, and according to regression equation the temperature, precipitation, the climate elements in this area were calculated
摘要通過測定和對比關中黃土剖面的磁化率數據,依據磁化率與溫度、降水量回歸方程,對該區全新世氣候要素進行了計算。With the widespread and profound impacts of global change on the natural elements and progress, the society and economy, and even the human activities, the study of global change has become one of the most active frontiers in the current earth science research field. especially, climatic and environmental changes of holocene and human history is a very important time scale of the study of global change. however, the geographic surroundings and the natural environment of the southern margin of tarim basin, which lies in the hinterland of eurasia continent, are so special that it is difficult to obtain the proxies indicating its environmental evolution
在多年來前人研究成果的基礎上,本文通過尼雅剖面年代解析度可達10a的沉積物質量磁化率、碳酸鹽碳同位素、粒度等氣候替代性指標及約特干剖面的地球化學元素、孢粉等氣候指標信息的結果分析,並結合達木溝、塔格勒等剖面的成果及相關資料,得出以下結論: ( 1 ) 、南疆塔里木盆地南緣中全新世6 . 7 3 . 0kab . p .以氣候溫暖偏乾的荒漠環境為總體特徵。O curve of dsdp607 v30 - 97 show that loess began to deposit on the terrace of the yellow river about 1. 20 ma b p, and passed thirteen climatic changes from drier and cooler to warmer and wetter later. the turn of sedimentation from alluvium to loess, an event of transformation from accumulation to down - cut of the yellow river, indicates a sharp tectonic uplift occurred around 1. 2 ma b p. key words : loess - paleosol ; susceptibility ; climatic changes ; tectonic movement ; yellow river ; yangfan section
通過對楊范剖面黃土地層巖性特徵沉積結構質量磁化率和頻率磁化率的分析及與深海氧同位素曲線的對比,劃分了剖面地層,初步確定了黃土沉積始於1 . 20 ma b p ,黃土沉積以來該區發生了13次大的乾冷暖濕氣候變化沉積轉型指示河流強烈加積轉變為河流侵蝕,代表約在1 . 20 ma b p發生過一次強烈的構造抬升事件。Relationship of archaeological sites distribution and environment from the paleolithic age to the warring states time in hubei province
