  • 本研究針對泰國西北部達府 (Tak) 地區,受西北-東南走向的王朝 (Wang Chao) 斷層切過的藍山 (Lansang) 國家公園附近,採集定向岩石標本進行顯微構造分析,並探討此區域中岩石的變形作用。
    以岩石顯微構造Rf /ψ應變分析法的結果得知,本區域為西北-東南向的背斜褶皺構造,主要葉理面為西北-東南的走向,傾角大致上都是往東北傾斜,褶皺的東翼傾角比較平緩,褶皺的西翼傾角比較陡峭。應變量在東北-西南向的剖面上的比較一致;西北-東南向的剖面上有愈北愈小、愈南愈大的趨勢。
    利用Flinn Diagram應變橢球體的變形量分析法的結果得知,東北-西南向的剖面上,顆粒大致上都被壓成扁平狀,且主應力為水平方向的擠壓力。西北-東南向的剖面上有愈靠南邊,顆粒愈扁平,且主應力為垂直方向的擠壓力;愈靠北邊的變形形態愈偏雪茄狀的拉伸模式。
    藍山國家公園附近經應變分析的結果,是由於造山運動產生了背斜褶皺的西翼接近垂直向的壓扁應變,而且整個西翼的變形量相當一致;之後造成的左移剪切運動,背斜東翼產生接近水平的應變,反應出此剪切帶左移逆衝褶皺東翼尾端之構造現象,而且其應變量有愈北愈小、往南增大的趨勢。
