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.
