| 中文摘要:在几乎所有有关东南亚的古构造再造中，人们普遍认为从泰国到马来西亚半岛存在着一条或多条长缝合带。但是这两地业已建立起来的有关缝合带的地质证据却与古构造模式依据的许多地质解释与推论相悖。除泰国难-程逸缝合带可能例外外，其他缝合带与俯冲过程的关系很值得快得怀疑。现行再造方案所提出的致使冈瓦纳块体与亚洲块体相联合的碰撞事件的时代始终是最关键的问题之一。就该区主要造山运动而言，能够对此难题做出解释的古生物、地层、火山岩、变质岩及构造方同的证据，给出了与模式不相一致的年代结果。 |

| “Suture Zones”in Peninsular Malaysia and Thailand:Implications for Palaeotectonic Reconstruction of Southeast Asia |

| Abstract:The existence of one or more long suture zones extending from Thailand to Peninsular Malaysia has been widely accepted in almost all the palaeotectonic reconstruction of Southeast Asia.Geological evidence from the areas where suture zones have been proposed in this two countries are not reconcilable with many of the inferences and interpretations of the geology on which the palaeoteconic models are based.With the possible exception of the Nan-Uttaradit suture in Thailand,the relationship of the other proposed "sutures"to subduction processes must be regarded as highly doubtful.The timing of the proposed collision event to bring together the Gondwana terrain with the Asian terrain,as envisaged in the popular reconstructin schemes remains one of the most crucial problem which need to be addressed by those advocating this concept.Palaeotological,stratigraphical,igneous,metamorphic and structural evidence which can shed light on this difficult question gives confilicting ages for the major orogenic events in this region. |
