中文摘要 | 臺灣海域可依其地形及地質特徵,可區分為六個地質區,即東海陸棚區、臺灣海峽陸棚區、高屏棚坡區、琉球弧溝區、加瓜海盆-海脊區及恆春海脊-綠島、蘭嶼區。各地質區間的界限,有些呈現明顯的地形及構造差異,有些表現地質特徵的漸變,呈現過渡帶的現象,較具爭議性。臺灣海域六個地質區性質不同,形成的時間先後不同,而其空間的分佈型態也相異。其特徵反應了大地構造環境及地質演化歷史。東海陸棚區的地質特徵為一新生代張裂大陸邊緣,臺灣海峽陸棚區是一個殘留新生代張裂邊緣,高屏棚坡區的特徵是個變形的上新世-更新世前淵,琉球弧溝地質區可以板塊隱沒帶視之,加瓜海盆-海脊地質區的特徵為深海平原及海脊,而恆春海脊-緣島、蘭嶼地質區代表擠壓變形的弧溝系統。 |
英文摘要 | The offshore area around Taiwan can be divided into six geological provinces on the basis of distinguished physiographic features. These geological provines are East China Sea Shelf, Taiwan Strait Shelf, Kaoping Shelf-Slope Region, Ryukyu Arc-Trench System, Gauga Basin and Ridge Region and Hengchun Ridge-Lutao and Lanhsu Region. Most of the major boundaries separating these provinces are clearly defined to distinguish from the other. Some boundaries are characterized by transitional features either in geological or physiographic aspects with uncertainty. These six geological provinces were formed with different geological ages and were distributed in different geological settings, reflecting tectonics and geological evolution in the Taiwan region. The geological provnice of East China Sea Shelf is characterized by a Cenozoic rifting continental margin whereas the Taiwan Strait Shelf can be considered as a relict Cenozoic rifting margin, The Kaoping Shelf-Slope Region has characteristics of a deformed Pliocene-Pleistocene foredeep. The Ryukyu Are-Trench Syetem is characterized by features resulted from subduction. Off eastern coast of Taiwan, the Guaga Basin and Ridge Region reflects the submarine sea floor characteristic of abyssal plain and ridge. The Hengchun Ridge-Luato and Lanhsu Region is characterized by a compressed arctrench system. |
