中文摘要 | 為推動10萬分之1海洋地質圖與海底沉積物分布圖之編製,將本國海域領海至鄰接區以及離島規劃了37區海域,並選定臺灣北部富貴角海域及西南部外小琉球海域,作為海洋地質圖和海底沉積物分布圖之試測及編製地區。其中,富貴角海域搭配有海上施測工作,外小琉球海域則屬現有資料之編繪整理。富貴角海洋地質圖地質構造中,有兩條正斷層和陸上逆斷層(金山斷層和崁腳斷層)位置相對應,可能是陸域斷層向海域延伸的證明。外小琉球海洋地質圖以近南北向的逆斷層和背斜為主要構造,而有部分背斜向北銜接圖幅東北角的泥貫入體。外小琉球海底沉積物分布圖以黏土質粉砂(clayey silt)沉積物為主,主要沉積來源為以曾文溪和高屏溪為主的陸上沉積物。 |
英文摘要 | In order to push for the compilation of the 1:100,000 scale Marine Geological Map and Sedimentological Map for Taiwan, we divided the territorial waters to the contiguous zone to 37 mapping units. The offshore areas of Fuguijiao in the northern part of Taiwan and the offshore areas of Wai-Siaoliouciou in the southwestern part of Taiwan were selected as areas for testing and compilation of the Marine Geological map and Sedimentological map. The survey was carried out at sea in the areas of Fuguijiao and existing data collected from the offshore area of Wai-Siaoliouciou was analyzed and mapped. Two normal faults were observed in a direction extending from two thrust faults on land, the Chinshan and Kanchiao Fault and extending to the offshore area of Fuguijiao. It might be the evidence of fault extension from land to the sea. In Wai-Siaoliouciou, the main geological structure thrusts in south to north direction and anticline axes are almost in north-southern direction. Some anticline axes extend from diapers at the north-eastern side of the map. The Wai-Siaoliouciou Sedimentological Map is composed mainly of mud (clayey silt). Sediment is conveyed mostly from the Zengwun River and Kaoping River. |
