中文摘要 | 從構造的發展來看,臺灣與阿爾卑斯山都是由地塊衝撞而成,有許多相似之處而為前輩所提及。衝撞的雙方在臺灣是一個歐亞大陸與海岸山脈島弧,在阿爾卑斯山是歐洲大陸陸塊與非洲大陸陸塊。儘管衝撞的一方在兩地不同,然而兩地各有一些油氣儲集封閉,形成發展上相同或不同,但在性質上總是相同。這兩個地區各有變形前緣及在前阻擋的古陸塊,陸塊內的裂谷因衝撞而復活,陸塊邊緣 也因衝撞產生縱向橫移斷層以及扭力斷層行列,在衝撞的遠端的推移帶縱或沉積物不同,也都有底辟作用,並有走滑斷層、平緩的背斜存在。油氣儲集存在這些構造運動造成的封閉內,雖然生、儲、蓋岩的年代都不相同,但油氣封閉的機制卻是一致。在非洲東北已有大油田及大油氣田被發現,相互比較,對臺灣西南部油氣探勘可有新的認識。 |
英文摘要 | In view of tectonic evolution, both Taiwan and Alps are products of crustal collisions and have a lot of similarities mentioned by Biq (1976). Although the Taiwan collision is continent-arc in type while the Alpine collision continent-continent, each has left in the orogenic framework a deformation front, a foreland paleohigh, a foreland basin area, a paleohigh marginal rift area and most importantly a collision slip zone with strike-slip faults, gentle folded structures and diapir structures. Hydrocarbon accumulates in various traps within these geological structures. Although the hydrocarbon source rock, reservoir and sealing rock in these two areas are different, the hydrocarbon accumulation mechanism is the same. Some giant gas fields were discovered in the NE Africa, especially in the deep sea area of east Mediterranean Sea, because of the deposition of hydrocarbon rich source rock in the rift basins, the prospect of hydrocarbon exploration in SW Taiwan deep sea area should be the same way. |
