dc.description.abstract | 台灣南部海域為隱沒轉為初始碰撞之板塊斜聚合區,直到現在弧陸碰撞仍在台灣南部海域作用著,故由北呂宋海槽往北延伸至台灣南部海域增積岩體之構造變化,為研究弧陸碰撞演化特色的絕佳區域。因此,本研究乃整合台灣東南海域隱沒至碰撞過渡區之海上多頻道震測資料,以強調地質構造上的連續性,對增積岩體東翼弧前盆地區域的構造演化特徵,做進一步的描繪及分析討論。
本研究將研究區域依構造特徵畫分為四個區域。21° 15' N以南之弧前盆地區為典型的隱沒構造,由逆衝活動主導著增積岩體弧前區域的發展。而弧前盆地於21° 15' N ~ 21° 30' N之間的明顯隆起,可能為一次新火山作用下形成的不規則噴發物質,並影響到後逆衝構造組的走向,使其衍生出一組橫移壓縮系統。在21° 30' N ~ 21° 45' N間的初始碰撞區,可清楚發現北呂宋海槽北段與南段基底偏移的情形,並由相鄰剖面顯示之構造觀察到北呂宋海槽北段乃由島弧內部之正斷層陷落所開啟,另一方面,於增積岩體東翼處,在島弧旋轉作用下將後逆衝構造楔形體(花東海脊之前身)再一次擠壓到盆地西緣處,而使盆地縮減終至關閉。21° 45' N ~ 22° 20' N處,則可發現到雙海槽系統經由正斷層作用而再度開啟沉積盆地,當中的台東海槽是與島弧內正斷層有關;而南縱海槽則是由後逆衝構造上的正斷層崩落所張開。 由震測剖面觀察到的構造特徵及分佈趨勢,發現後逆衝斷層構造,在受到斜向碰撞作用下,可能將弧前盆地沉積物併入增積岩體東翼或是附入島弧西側,因此增積岩體之外形得以往北逐漸壯大且弧前盆地構造也漸趨關閉。。 從本研究所描繪出的構造分佈,當中的主要後逆衝斷層組,可顯示出研究區域中主應力之分佈呈現弧形分佈,與台灣島上之應力均連續而相符。此外,本研究於弧前盆地21° 15' N處,所觀察到的大尺度右移壓縮構造,不僅改變後逆衝構造之趨勢走向,其亦為台灣東南海域數值模擬中,應力於單海槽及雙海槽交界處的變化區域所在。 | zh_TW |
