摘要(中) 菲律賓海板塊在台灣東北部向西北方向隱沒至歐亞板塊的下面，因為南沖繩海槽張裂逐漸由東北向西南移動，因此，在台灣東北處，台灣造山運動從早期到晚期，由地殼抬升轉變為塌陷。台灣東北部正處於後碰撞時期，因為南沖繩海槽張裂，在台灣東北外海有多東北—西南走向的正斷層，使得台灣東北部外海多呈現半地塹和地塹的地形樣貌，在基隆外海，根據多音束水深（Multi-beam）以及單音束（Single-beam）的資料，在本研究區域發現有錐狀突起的構造，熱液活動旺盛，微震活動頻繁，本研究區域為基隆海底火山範圍，而出露的海底錐狀體是基隆海底火山頸，基隆海底火山頸周圍可發現許多噴氣。本研究使用新海研2號 0082-KL1、0093航次的水深、電火花反射震測、船載底質剖面和EA640的資料，在基隆海底火山附近收集了15條電火花反射震測剖面和15條與電火花反射震測剖面共線的底質剖面，來探討流體特徵、火成岩體特徵和噴氣分布，並且進而討論噴其分布的原因。本研究利用了電火花反射震測剖面觀察深部地層的流體特徵、火成岩體特徵和震波訊號極性反轉特徵，接著利用底質剖面和EA640的資料觀察噴氣特徵來去觀察特徵上面是否有噴氣出露至海床上，以便證實在電火花反射震測剖面上觀察到的特徵是否活躍中，利用研究結果來加以輔助說明、證實前人的研究，最後根據這些特徵可以發現火成岩體、流體特徵是沿著特定方向分布，此特定方向上可能有一個斷層帶存在，而岩漿沿著此斷層帶移棲至淺部地層，造成流體特徵……等特徵的產生。 摘要(英) In the northeastern Taiwan, the Philippine Sea Plate subducts northwestward beneath the Eurasian Plate in northeastern Taiwan. Because the extension of the southern Okinawa Trough gradually migrates from northeast to southwest, from the early stage to the late stage, the Taiwan orogen transferred from the collision stage to the collapse stage due to the reverse subduction polarity. Nowadays, the northeastern Taiwan is in the post-collisional stage, due to the extension of the southern Okinawa Trough, there are some NE-SW trending normal faults which caused the offshore northeastern Taiwan in the graben and half-graben features. In the Keelung offshore, according to multi-beam and single-beam data, there is a cone-shaped structure was found in this study area which is with strong hydrothermal activity and frequent microseismic activity. This study area is in the Keelung submarine volcano range, and the emergency submarine cone is the neck of the Keelung submarine volcano. Many gas plumes can be found around the neck of the Keelung submarine volcano. This study used the data of water depth, sparker seismic reflection survey, sub-bottom profiles and EA640 data which collected from NOR2-0082-KL1 and NOR2-0093.This study collected 15 sparker seismic reflection profiles and 15 collinear sub-bottom profiles of the spark reflection seismic profiles which are used to explore the fluid characteristics, igneous rock characteristics, and the distribution of gas plumes to discuss the reason for the distribution of these characteristics. Observing the fluid characteristics, igneous rock, and seismic signal reverse polarity characteristics of deep strata by using spark reflection seismic profiles in this study Then, using the bottom profiles and EA640 data to observe the gas plumes characteristics and prove whether there are gas plumes erupt to the seafloor which is above the features, in order to confirm whether the features which are observed on the sparker seismic reflection profiles are active. Using the research results to assist in explanation and previous research confirmation. Finally, based on these features, it can be found that the igneous rock characteristics and fluid characteristics are along the Distribution which is in a specific direction, there may be a fault zone in this specific direction, and the magma migrates to the shallow strata along this fault zone, causing fluid characteristics... and other characteristics. 關鍵字(中) ★ 基隆海底火山
