新疆塔里木盆地西—西南缘泥盆—石炭纪四射珊瑚

塔里木盆地西—西南缘石炭纪地层层序清楚,化石丰富,是新疆研究石炭系的良好地区之一。目前海相泥盆纪地层中有化石佐证的只有中泥盆世,而早泥盆世地层存在与否尚难定论。描述珊瑚计22属22种。中泥盆统3属3新种,石炭纪19属12新种。塔里木盆地西—西南缘的中泥盆统称克孜勒陶组,上泥盆统为奇自拉夫组,属陆相沉积。石炭系自下而上为下统库山河组、克里塔克组、和什拉甫组;中统卡拉乌依组、阿孜干组;上石炭统塔哈奇组、克孜里奇曼组。

THE DEVONIAN AND CARBONIFEROUS TETRACORALS FROM WESTERN AND SOUTH- WESTERN MARGINS OF TARIM BASIN,XINJIANG

Marine sediments of Devonian and Carboniferous are widely distributed on the western and south -western margins of Tarim Basin, and exposed in simple structures, yielding abundant and a great variety of fossils including fusulinids,foraminiferas, corals and conodonts etc. . The tetracorals, collected mainly by Comprehensive Scientific Expedition, includes 22 genera and 22 species, with 14 new species. Middle Devonian tetracorals from Aketao county, consist of 3 genera with 3 new species: Cyathophyilum (Peripaedium) xinjiangense (sp. nov. ), Disphyllum carinatum (sp. nov. ) and Hexagonaria talimuensis (sp. nov. ). Lower Carboniferous tetracorals from Aketao and Wushi counties include 12 genera with 12 species (6 new species): Dematophyllum xinjiangense,Psudouralinia talimuensis (sp. nov. ), Saleelasma xinjiangensis (sp. nov. ). , Yuanophyllum kansuennse, Y. xinjiangense(sp.nov. ), Y. sp. A, Palaeosmilia murchisoni, Di-bunophyllum confertum, Neoclisiophyllum aketaoense (sp. nov. ), Siphonodendron aketaoensis (sp. nov. ). Lithoslrotion portlocki, Keuichouphyllum sinense gracile, Lonsdaleia aketaiensis (sp. nov. ), Kizilia sp. Middle Carboniferous tetracorals from Aketao and Yechang counties include 6 genera with 6 new species: Donophyllum xinjiangense(sp. nov. ), Hillia Xinjiangensis(sp. nov. ), Eokoninckocarinia aketaoensis (sp. nov. ) , Neokoninc - kophyllum talimuense(sp. nov. ) , Pseudozaphrentoieds aketacensis (sp. nov. ), P. tal-imuensis (sp. nov. ) and Caninophyllum sp. Upper Carboniferous tetracorals from Hetan county only contain Eowentzpilellites kunlunshanensis.
