简介:摘要:煤是中国的主导的精力资源。煤地质的探索是煤工业的持续开发的基础。自从1990年代末,在中国煤地质学和探索技术的进展在下列方面被显示出。(1)煤地质学的基本研究从传统的地质的研究改变了到地球系统科学;(2)突破为煤资源在综合探索技术被完成了;(3)煤和coalbed甲烷资源的评估为为中国的煤工业和大煤底的建设做的macropolicy提供重要基础;(4)重要进展在在煤使用信息技术被做了地质的探索和3S(GPS,GIS,RS)技术。目前并且时间的一个时期以后,中国煤的主要任务地质的技术如下:(1)在东方中国和深采矿的地质的问题解决资源代替问题;(2)在华中,和资源问题的精力底解决复杂区域的综合的煤探索的问题由煤利用导致了;(3)作努力在西方的中国提高地质的研究的水平和煤累积盆的资源评估;(4)加强干净的煤技术的地质的研究;(5)在现代的煤采矿和安全生产加强这些问题的地质的研究;(6)在煤资源和主要地质的调查支持信息技术。
简介:对从中国大陆人和邻近的块的白垩纪paleomagnetic数据寒武纪用原则被收集获得可靠、高精确的paleomagnetic数据并且注意paleobiogeography和构造进化的协作的类似。中国大陆人块在建议全球paleocontinents的重建上被贮藏与几乎一样的规模。因此,包括中国大陆人块,全球大陆在赤道的南部的方面上沿着纬度变化在期间,这能清楚地被认出早古生代。在古生代的、中国大陆人,块仍然在Laurentia,西伯利亚和Gondwana盘子之中位于,跟随向北的西伯利亚板的快移动,在在Laurentia和Gondwana盘子的西方的部分的一个纵贯的方向的合并,和Iapetus和Rheic海洋是subducted,最后形成一致Pangea在晚古生代。东方Gondwana的澳大利亚、印度的盘子向南逐渐地移动了并且分散,继续扩大Paleo-Tethys海洋。中国大陆人和邻近的块仍然位于Paleo-Tethys海洋,保存了分散的地位,逐渐地向北移动,沿着northsouth取向变化直到的出现特征二叠。另外,一系列本地碰撞发生了在期间三叠纪,并且因而,大多数中国大陆人块被混合进Pangea,除了Gangdise和喜玛拉雅的块。有在侏罗记的东方亚洲大陆的逆时针方向的旋转,向北,在在白垩纪期间改变度的中国大陆的移植,而是喜玛拉雅、印度的盘子没在这个时期期间碰撞进中国大陆。
