迄今为止,保罗纪生物礁在国内报道极少,且仅限于西藏西南部。本文报道的保罗纪生物礁是近3年中作者等在气候十分恶劣的高寒地区——藏北进行油气地质勘探过程中发现的,其产地共3处,即安多县东巧区、巴青县马如乡和索县一带。所发现的礁体不仅类型丰富,造礁生物种类繁多,而且礁体均产于近年来我国在藏北地区进行油气勘探的目的层——侏罗系中。这一发现不仅填补了藏北地区侏罗纪生物礁领域的空白,丰富了我国侏罗纪生物礁的类型,而且对研究该区大地构造的演化史具有

So far, Paul Reef reefs rarely reported in the country, and only limited to the southwestern part of Tibet. The Paleochromological reefs reported in this paper were discovered by the author during the recent 3 years in the alpine region where the climate is very harsh - the exploration of oil and gas geology in the north of Tibet. There are 3 sites of origin in this area, that is, Dongqiao District, County horse and rural areas such as cable. The discovered reefs are not only rich in types but also have a large variety of reef-forming organisms. Moreover, the reefs are all produced in the target layer of Jurassic in our country for oil and gas exploration in northern Tibet in recent years. This finding not only fills the gaps in the Jurassic reefs in northern Tibet, but also enriches the types of Jurassic reefs in China,
