Since 1986 lab determination of radiogenic heat production(A) for 97 rock specimens including outcrop samples (n=46) and core specimens(n=51) collected from the Himalayan Block in South Tibet and the Lhasa Block north of the Yarlung-Zangbo River has been conducted. Though the core samples(mainly of sedimentary rocks, n=42) occupy 53% of the whole sampling, they are all from four drillholes of limited coverage.

Since 1986 lab determination of radiogenic heat production(A) for 97 rock specimens including outcrop samples (n=46) and core specimens(n=51) collected from the Himalayan Block in South Tibet and the Lhasa Block north of the Yarlung-Zangbo River has been conducted. Though the core samples(mainly of sedimentary rocks, n=42) occupy 53% of the whole sampling, they are all from four drillholes of limited coverage. The A valuc was also measured for 9 cores of ultrabasic rocks from one of driUholes in the Luobusha Ultrabasic Rock Belt. Of the outcrop samples 35 are collected from 15 granitic rock bodies (5 for South-Tibet and 10 for North-Tibet) along Nelamu to Anduo with relatively large sampling coverage. Therefore,the determination results may define an average order of magnitude of A for granitic rocks of the South-Central part of Tibet. The remaining 10 outcrop specimens are from volcanic (n=7) and ultrabasic (n=3) rock bodies in the region near Naqu and Tongqiao. Owing to the data limitation, no definite conclusions can be derived for these rock types. The statistics of the lab-determined A values of granitic rocks gives average heat production values A of 3.2±1.5μW/m~3 and 2.6+1.6μW/m~3 for the South-Tibetan granitic rocks (n=12) and North-Tibetan granitic rocks (n=24), respectively. Compared with the statistical results for 17 heat flow provinces of global scale, both are of moderate level in abundances of the radioheating elements. Moreover, the Th/U ratios for the two regions are very similar, being 4.4±2.7 and 4.5±1.4, respectively, thus identifying an intermediate extent of magma differentiation. These results imply that(1) the order of magnitude of A accepted by the authors in the previous studies is adequate; (2)the average heat production value of granitic rocks as a main heat-generating rock type does not show any anomalous features; in other words. it is the tectonic evolution process and thereby induced deep-seated thermal activities that may be the major mechanisms responsible for the formation of high heat flow anomaly in both South-and North-Tibet.

测定了采自喜马拉雅和冈底斯地块露头和钻孔的97块岩石标本的放射性生热率(A),结果表明:藏南花岗岩(n=12)和藏北花岗岩(n=24)的平均生热率A值分别为3.2±1.5μW/m~3和2.6±1.6μW/m~3,与全球17个热流省的统计数据相比,两者均具有中等的放射性生热元素丰度;两者的平均钍铀比十分接近,分别为4.4±2.7和4.5±1.4,岩浆分异程度属中等。这些说明了:(1)本文作者在前期研究中选用的A值量级是适宜的;(2)花岗岩类作为壳内主要的放射性生热岩层,其生热率A值并未呈现异常量级。换言之,应着重从构造演化过程及其诱发的深部热作用机制,探讨藏南藏北高热流异常的成因。

利用武汉测绘科技大学在1993年、1995年观测的两期GPS资料,具体分析了青藏高原各块体相对运动情况。目前青藏高原大约以33.4mm/a,N30°E方向向西伯利亚运动,其中巴颜喀拉块体、羌塘块体、拉萨—冈底斯块体和喜马拉雅块体大约分别以17.3mm/a±3.1mm/a,N35°E;25.7mm/a±5.1mm/a,N33°E;38.9mm/a±6.1mm/a,N29°E;46.0mm/a±6.2mm/a,N27°E方向朝西伯利亚运动,而西藏块体大约以28.5mm/a±5.0mm/a速率,N31°E方向朝西伯利亚运动,这些结果与地质结果符合。文中还给出了各块体相对运动的欧拉向量。

On the basis of the GPS data and the relative gravimetries in some GPS stations, observed repeatedly in 1992 and 1996 in the middle section of the Himalayas,the crust movement and its mechanism are analyzed and discussed.The results show that the Jiangzj(Himalayas)and Lasa Blocks under the horizontal compresion from northern and southern sides are shortening at a rate of 12mm/a,that is much less than the plate moving rate of 50~60mm/a reported by Molner.The rate of vertical movement(uplift)is less than...

基于1992、1996年两期GPS重复观测资料,对喜马拉雅中段的地壳运动及其机制作了初步分析和探讨。结果表明:江孜(喜马拉雅)块体在喜马拉雅南侧和雅鲁藏布江北侧的水平挤压下,以12mm/a缩短,这与Molner等所给出的50~60mm/a相比要小得多;喜马拉雅的垂直运动(隆起)速率各点平均值仅为5.3mm/a。最后,对喜马拉雅和青藏高原隆起的机理作了初步探讨。
