多目标地球化学调查在成都平原的实践

通过在中国西部地区成都平原首次开展的多目标地球化学调查，研究了深层样元素的基准值及浅层样元素的分布特征，并利用元素的分布特征判断隐伏构造和隐伏岩体；探讨了在农业地质、环境污染、人体健康、天然气预测、pH值计算等多目标的地球化学研究。     

义敦成矿带铜银铅锌锡矿产资源调查评价进展与潜力

义敦成矿带地处独特的大地构造部位，经历了复杂的地质构造演化和强烈的岩浆活动，成矿条件优越，矿产资源丰富。1999年实施国土资源地质大调查以来，相继发现了普朗、松诺、卓玛斑岩铜矿；砂西、热朗泽、夏隆等银铅锌矿；热隆、脚根玛锡矿；打马池觉铜金矿等一批具有重要找矿前景的矿床(点)。该地区矿产资源勘查工作程度低，蕴藏着较大的找矿潜力，有望成为国家级重要的有色及贵金属矿产勘查和开发基地。     

Study of Triggering Action Between the Mani （Ms7.9） and the West Kunlun Mountains Pass （ Ms 8.1 ） Great Earthquakes and Their Dynamic Background

Based on Coulomb static stress variation, the stress trigging action of the Mani ( Ms7.9, Nov.1997) earthquake on the West Kuulun Mountains Pass (MsS.1, Nov. 2001 ) earthquake is researched. Results of different source mechanism resolutions show that a 10_3 MPa Coulomb stress due to the Mani earthquake was added to the fracture fault of the Kunlun earthquake, and this may shift the broken date to about 10 years earlier, and infer that the stress level in the crust is not low. Comparing the relationship between strong earthquake strength and frequency and earth rotation change, it is shown that the strength‘s decrease and the variation period‘ s shortening of earth rotation are important controlling factors on strong earthquake activity. This great event with Ms = 8.1 took place probably due to a gradual strengthening background of regional stress field within the Qinghai-Xizang block in the period of acceleration of change of day‘s length and stress triggering from the Mani earthquake.     

Research on Earthquakes in Cities of China

In this paper, we briefly describe the general destruction caused by historic earthquakes in major cities of China, preliminarily analyze the heaviness and widespread occurrence of earthquakes in cities of China, and suggest that research on scenario earthquakes in cities should be developed as a part urban disaster reduction research.     

Characteristics of Tectonic Deformation and Mechanisms for the Active Maxianshan-Xinglongshan Fault System in the Lanzhou Area

A detailed investigation permitted us to obtain quantitative data concerning fine geometric structures of 4 faults of the active Maxianshan-Xinglongshan fault system and the latest movement along them. Of them the northern Maxianshan border fault is a large-scale, strongly active Holocene reverse sinistral strike-slip fault, the other 3 faults, the southern Maxianshan border fault and the southern Xinglongshan border and the northern Xinglongshan border faults are the accompanying active late-Pleistocene thrust faults, which are incorporated into the main strike-slip fault, the northern Maxianshan border fault at depth. It is the most important earthquake-controlling fault in the Lanzhou area, the fault influences and constrains the seismic activity in the area.

在实践中探索预防土地违法的新途径——对河北省冀州市在预防土地违法中实施“关口前移，提前介入”的情况调查

根据部领导指示,部执法监察局组成的调研组不久前到河北省冀州市,针对该市通过关口前移,提前介入,防范国土资源违法行为发生工作情况进行了调查。通过调查和分析,我们感到,冀州市的做法,完全符合部领导在2002年全国国土资源执法监察工作会议上提出的,要从源头防范国土资源违法行为和努力调动地方执法监察工作积极性的要求,方向明确,重点突出,富有特
