Abstract: The Mesozoic volcanic rocks distrbuted zone in the eastern parts of Zhejiang,Fujian andGuangdong Provinces is a new area for oilandgas exploration,As a result of work conductedinrecent years,the features of the volcanic rocks distributed zone have been basically clarified.It can be divided into three types of sedimentary basins:situated under,among and abovethe main boby of volcanic rocks.There are two late Paleozoic marine facies basins and one late Triassic-early Jurassic al-tenated marine and terrestrial facies basin under the main boby of volcanic rocks.Thesebasins were seriously destroied,but the source rocks with low degree of evolution are betterconserved in the late Paleozoic marine facies basin at the boundary of Zhejiang and FujianProvinces.It would be a promising gas-bearing region for exploration.The sedimentary basin located among the main body of volcanic rocks can be divided intothree zones: the eastern,central and western zones.The terrestrial lake basin in the westernzone and the aIternated marine and terrestrial facies sediments in the eastern zone are promis-ing for oil and gas exploration.The Cretaceous-Tertiary basins over the main body of volcanic rocks are located at thesouthern and northern end of the volcanic rocks zone,The Changhe-Wangpanyang,Ningpo,Shengxian basins at northern end and the Dongguan basin in southern end,each covering anarea of about 1000sqkm respectivelly,possess conditions of oil and gas generation.They areworth to be explored further.

Key words: eastern parts of Zhejian Fujian and Guangdong, volcanic rock, sedimentary basin, oil and gas resource

摘要： 浙闽粤东部中生代火山岩分布区是探索寻找油气的新领域.经近几年的工作,基本明确火山带特征,并分为主体火山岩之下、之中、之上三类沉积盆地.主体火山岩之下埋藏着二个晚古生代海相盆地和一个晚三叠至早侏罗世海陆交互相盆地,均遭受比较严重破坏,而渐闽交界的晚古生代海相盆地生油条件好,演化程度较低,有寻找气的希望;主体火山岩之中的沉积盆地分为东、中、西三带,西带陆相湖盆,东带海陆交互相沉积是寻找油气有希望地区;主体火山岩之上的白垩一第三纪盆地,集中在火山带南北两端,北端的长河一王盘洋,宁波,嵊县等盆地,南端的东芜盆地,面积都在1000km²左右,有生油条件,值得进一步勘探地区.
