     Up to now, there are more than 20 known oil shale occurrence spots in Yunnan, resource amount 158 million t, convertible into shale oil 5. 5 million t. The rock series with oil shale are from Cambrian Lower Se- ries to Neogene, mainly in Lower Cambrian, Middle Devonian near bottom, Middle Jurassic, Upper Cretaceous, Neogene Miocene and Pliocene, etc. As to the sedimentary type, the others are inland lacustrine facies besides Lower Paleozoic is littoral - bay lagoon facies and offshore plain facies. The thickness of oil shale is over the lowest minable thickness lm. And the oil - bearing ratio can meet or over the boundary grade of oil shale 4%. The oil - bearing ratio of Lower Paleozoic oil shale is rather high generally, the highest oil - bearing ratio is to 27. 07 %. It is desirable that the oil shale in Yunnan will become an important non- routine oil- gas resources.
