伊朗珊瑚在新疆的发现

THE DISCOVERY OF IRANOPHILLUM IN XINJIANG

本文描述的伊朗珊瑚(Iranophyllum)是1971和1984年第一区调队在新疆南部昆仑山下二叠统黄羊岭群和叶桑岗组采集的,共4新种和1未定种,名单是:Iranophyllum xinjiangense(sp.nov).Ir.kunlunense(sp.nov.),Ir.clisiophylloides(sp.nov.),Ir.neoclisio-phylloides(sp.nov.),Ir.sp.A等.与其共生的有(?)类:Sumatrina annae,Verbeekina of.verbeeki,paraverbeekina of.umbi-lcata,Polydiexodina sp.,Yangchienia sp.,Neo-misellina sp.,parafusulina sp.,Chusenella sp.,Afghanella?sp.,腕足:Neospir-ifer sp.,Martinia sp.,Stenoscisma sp.,Waagenoconcha sp.,四射珊瑚:Amplexo-carinia sp.,Huangophyllum sp.,Lytvolasma sp.,plerophyllum sp.等.因此,含Ira-nophyllom的黄羊岭群和叶桑岗组应属同一层位,它们与新疆喀喇昆仑地区空喀山口组、西藏阿里地区龙格组及文部组是相当的.

In 1971 and 1984, Iranophyllum described were collected by No.1 Regional Geological Serveying Party in the lower Permian Huangyangling group and Sanggan formation at the foot of the southern Kunlun mountains, with four new species and one undefinited species, i.e. Iranophyllum xinjiangense (sp.nov. ), Ir.kunlunense (sp. nov.) , Ir.clisiophylloides (sp.nov.) , Ir.neoclisiophylloides (sp.nov.) , Ir. sp. A, etc. Those associated are Fusulinidz: Sumatrina annae, Verbeekina of. verbeeki, pa-raverbeekina cf. umbilicata, polydiexodina sp., Yangchienia sp., Neomisellina sp., parafusulina sp., Chusenella sp., Afghanella? sp., Brachiopoda: Neospirifer sp., Martinia sp., Stenoscisma sp., Waagenoconcha sp., Tetracoralla: Amplexocarinia sp.r Huangophyllum sp., Lytvolasma sp., pterophyllum sp., etc. Thus, the Huangyang group and Yesanggang formation bearing Iranaphyllum in Karakunrun mountain of Xin- Jiang must belong to the same horizon and correspond to formation. Wenbu formation in Ary region of Tebet.
