Three Alkali-Rich Intrusive Rock Belts Newly Discovered in the Mt. Kunlun-Mt. Altun Region, Xinjiang, China

The newly discovered three alkali-rich intrusive rock belts in the Mt. Kunlun Mt.Altun region of southern Xinjiang are the Lapeiquan-Yitunbulak alkali-rich intrusive rock belt,the Gez-Taxkorgan alkali-rich intrusive rock belt and the Beilisai-Abulash alkali-rich intrusive rock belt. The former two belts were formed during the Yanshanian period, and the third one was formed during the Himalayan period, which is the youngest alkali-rich intrusive rock belt in China. The discovery of the alkali-rich intrusive rock belts is of great significance in shedding light on the history of tectono-magmatic activities in this region.     

Practising geographical knowledge: fields, bodies and dissemination

In this article we make a case for a renewed emphasis upon some of the generic, albeit often tacit, spaces of practice that we share across our sub–disciplinary boundaries. In this we seek to emphasize the ways in which everyday actions make up the grander facades of institutional agendas, empirical projects and disciplinary schools of thought. To achieve this we trace the performance of disciplinary contours and identities across three important sites: the field, the body and the act of dissemination. There are, we will argue, significant commonalities that bind us as disciplinary practitioners in terms of how we perform within and across these sites, and indeed, how we join them up through our practices.     

充电激发极化法在金属矿上的应用

充电激发极化法是矿山物探的一种主要方法，其兼有充电法与激发极化法的特点，可利用已有的工程，最大限度地了解地下三度空间地球物理场的分布情况，解决地质问题。概述了其理论基础和方法技术，并列举了该方法在多个金属矿上的应用实例。     

川南S8滑坡体不稳定现象分析与防治

S8滑坡体后壁出露有新鲜滑动面，两侧呈双沟同源，坡体出现大量裂缝，前缘缓慢推移等，充分说明该滑坡体正处于不稳定状态。主要原因是：季节性洪水侵蚀滑坡体，前缘出现了临空面，使前缘支撑作用减弱；滑坡体内裂隙发育，裂隙水动力作用使滑动面抗滑能力降低；邻近采煤区造成的采动裂隙增加了水动力作用。该滑坡体裂隙丰富，保水性差，不利于植物生长；滑坡体边缘不断垮塌造成水土流失，沉积物淤塞下游河谷。防治措施有：在滑坡体后壁修筑排水沟，关闭邻近小煤窑，在前缘冲沟里构筑堡坎以减小水侵蚀作用；在冲沟里构筑拦砂埂，抬高沟底阻止切向侵蚀，以稳定滑坡体前缘。
