中文摘要 | 根據震測剖面的研究顯示臺灣-新畿褶曲帶及其附近含有四種構造形貌:1.擾亂帶 (disturbance zone),2.撓曲帶(buckling zone),3.平行帶(parallel zone),4.張裂構造 覆蓋(overprint)帶。在區域性分佈上,從西北往東南方向在構造上的變化是平行帶-撓曲帶- 擾亂帶-張裂構造覆蓋帶,這種變化顯示在始新世-上新世時期盆地穩定地加深,到了上新世 時期發生壓縮作用形成了撓曲帶,最後則發生張裂運動形成了沖繩海槽。撓曲帶在臺灣盆地 內分佈最寬廣,往西南則變窄。在臺灣盆地的東北部以大型背斜構造為主,往西南則漸變成 狹窄的褶曲帶。褶曲構造應是在上新世以後才發生,因為上新世以前的地層並無褶曲現象。 在古第三紀的盆地架構中,臺灣盆地東南邊的界限應是現今沖繩海槽張裂的位置,但當時沖 繩海槽當未發生,所以古第三紀時臺灣盆地的東邊應是以琉球脊(Ryukyu Ridge)為其盆地邊 界。 |
英文摘要 | Study of seismic sections indicates that the following four structure styles exit in the Taiwan-Sinzi fold zone and its vicinity : I,disturbance zone, 2,buckling zone, 3,parallel zone, and 4.rifting overprint zone. The trend of these zones from northwest to southeast is parallel zone-buckling zone-disturbance zone-rifting overprint zone. The parallel zone indicates that the basin deepened steadly during Eocene to Pliocene. The buckling zone was formed as a result of the compression during Pleistocene. Okinawa Trough developed due to the rifting during or after Pleistocene. Buckling zone was formed after Pliocene and is wide in the Taiwan Basin and becomes narrow to the southwest. Large scale syncline exit northeast to the Taiwan Basin and narrow folded zone exits southwest to the Taiwan Basin. Folded zone should have happened after Pliocene since there are no folded structures before Pliocene. The eastern boundary of the Taiwan Basin is the Ryukyu Ridge in the Paleogene since the Okinawa Trough has not been formed at that time. |
