伊朗珊瑚在新疆的发现

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.     

Stratigraphic Implications of Skeletal Microfossils from the Cambrian of Korea: A Preliminary Report

Diverse small shelly fossils and other associated fossils were recently recovered from the Cambrian Hanaeri section, southwestern Mungyeong, Korea. The fauna includes conoidal problematica, poriferans (sponge spicules), coeloscleritophorans (chancelloriids), brachiopods, monoplacophorans, trilobite (?) fragments, echinoderms, and conodonts. A preliminary assessment of faunal associations, stratigraphic implications, and the correlation of these skeletal fossils is given, based on occurrences of Actinotheca cf. mira (He), Microcornus sp., Torellela laevigata (Linnarsson), Torellela sp., Archiasterella quadratina Lee, Chancelloria sp., Lingulella sp., Prototreta sp., Phakelodus tenuis (Müller), Phakelodus elongates (An), Hertzina sp., and Furnishina sp.

Mississippian foraminifers from the Onimaru Formation in the Hikoroichi area, South Kitakami Belt, Northeast Japan

Abundant foraminifers were found from the Mississippian Onimaru Formation distributed in the Hikoroichi area of the central part of the South Kitakami Belt, Northeast Japan. They include Brunsia pulchra, Archaediscus sp., Paraarchaediscus? sp., Neoarchaediscus? sp., Palaeotextularia spp., Climacammina, spp., Tetrataxis spp., Haplophragmella sp., Lituotubella? sp., Forschiella sp., Cribrospira sp., Bradyina spp., Janischewskina sp., Endothyra spp., Planoendothyra aljutovica., Endothyranopsis compressa, E. crassa, Omphalotis samarica, Eo-staffella spp., Mediocris breviscula, and several others. The Onimaru foraminiferal fauna is similar to those re-ported from MFZ (Mamet Foraminiferal Zone) 15-16. This supports a late Visean (V3b-V3c) age of the formation, which has been proposed previously by rugose corals.

陕西镇安石炭纪四射珊瑚新属种

本文描述陕西镇安西口石门垭下石炭统顶部及中石炭统底部的四射珊瑚9属11新种。 1982年6月笔者随同中国地质科学院“石炭二叠系界线”专题研究队丁蕴杰等在陕西南部镇安县西口区石门垭测制剖面。该剖面中所采早、中石炭世四射珊瑚交由笔者鉴定。本文即为这批材料中的新属种,共9属(包括3新属、2新亚属)11新种。石门垭剖面中、下石炭统为连续沉积,岩性均为灰、浅灰色厚层灰岩。此界线上下发现有四个主要珊瑚化石层,自上而下产: 4.Acrocyathus xikouensis sp.nov.,Amandophyllum xikouense sp.nov.,Carruther-sella(Liuzhouia) shimenyaensis subgen.et sp.nov.,Koninckocarinia shaanxiensis sp.nov。,Kionophyllum sp.,Amygdalophylloides sp.和 pseudostaffella。 3.Liuia typica gen.et sp.nov.和pseudostaffella。 2.Semenoffia (pseudosemenoffia) typica subgen. et sp.nov.,Carruthersellazhenanensis sp.nov.。 1.paranemistium typicum gen.et sp.nov.,Cystilophophylloides typicus gen.et sp.nov.,C.shimenyaensis gen。et sp.nov.,C.xikouensis gen.et sp.nov,Arachnolasmaspp.,Amplexocarinia sp.,Zaphrentoides sp.,Siphonodendron sp.,Protocarcinophyllum sp. 上列层3-4内产蜓仅pseudostaffella,故时代为中石炭世早期pseudostaffella带。层1产产大量Arachnolasma种群及Protocarcinophyllum其时代定为早石炭世晚期似无疑问。层2中未采得蜓类,其时代据四射珊瑚Carruthersella的存在暂定为早石炭世末期。丁蕴杰同志给予笔者研究这批材料的机会并与夏国英、赵松银等同志共同采集化石,欧阳萱、金同安等同志给予笔者支持和帮助均此致谢。     

甘肃酒泉盆地早白垩世植物化石及其古气候意义

首次较系统报道了产于甘肃酒泉盆地下白垩统的植物化石,分为两个植物组合。Athrotaxites-Solenites组合产于赤金堡组上段,有Solenites luanpingensis Wang,Pityocladus cf.i waianus(ishi)Chow,Pityocladus sp.,Athrotaxites berryi Bell等,时代大致为早白垩世早期,反映潮湿或半干旱半潮湿气候。Brachyphyllum-Pseudofrenelopsis组合见于中沟组上部,包括Sphenopterissp.,Pseudofrenelopsis dalatzensis(Chowet Tsao)Cao ex Zhou,Cupressinocladus elegans(Chow)Chow,Cupressinocladus sp.,Pagiophyllumyumenense sp.nov.,Pagiophyllumcompressum sp.nov.,Pagiophyllum sp.,Brachyphyllumningshiaense Chow et Tsao,Brachyphyllumobtusum Chow et Tsao,Elatocladus sp.,Podozamites sp.,Carpolithus sp.等12种,时代为Aptian-Albian期,反映干旱型气候。     

湘西黔东上奥陶统临湘组的三叶虫

湖南西部和贵州东部奥陶系临湘组,地层厚度甚小,但含有较丰富的三叶虫化石,经作者研究共计11个属15个种和2个未定种,其中包括1个新属Dayongia(gen.nov.)和7个新种:Madygenia exsculpta sp.nov.,Madygenia tuberculata sp.nov.,Davongia brevica gen.＆ sp.nov.,Dayongia longicephala gen.＆ sp.nov,Eobronteus hunanensis sp.nov.,Shuma-rdia songtaoensis sp.nov.,Encrinurells exsculpta sp.nov.。这个动物群除具有我国地方性色彩外,同时具有与欧洲动物群明显的近似性。其时代应属晚奥陶世,相当于欧洲Ashgill期。     

云南西部施甸地区中泥盆世四射珊瑚

本文描述的四射珊瑚采自云南省西部施甸地区中泥盆世马鹿塘组及何元寨组。描述了马鹿塘组珊瑚5属5种,2个未定种,并建立1个珊瑚组合:Metrionaxon yunnanense-Neaxon inopinata组合,包括Metrionaxon yunnanense sp.nov.,M.sinense sp.nov.,Neason inopinata(Prantl),Neaxon sp.,Metriophyllum gracile Schluter,Barrandeophyllum?sp.,Amplexocarinia yunnanensisn sp.nov.等。该组合的时代为中泥盆世早期(Eife lian)。描述了何元寨组1属,1个亚种:Peripaedium planum planumBirenheide.本组时代为中泥盆世晚期。这一珊瑚动物群与我国华南区珊瑚动物群截然不同,而与欧洲珊瑚动物群非常相似。     

藏北申扎一带下奥陶统拉塞组的发现及意义

吉林省地质调查院在进行1：25万《多巴区幅》区域地质调查时，在西藏北部申扎县一带首次发现一套富含北方珠角石动物群Armenoceras sp.,Wutinoceras sp.,Discoactinoceras multiplerum Kobayashi,Adaomsoceras sp.,Sactoceras sp.,Ordosoceras sp.,Oncoceratida,Ormoceratidae,? Curtoceras sp.,Ormoceras sp.,Liulinoceras sp.,Deiroceras cf.globsom Zholt et Shen及腕足类、牙形刺、苔藓虫、海百合茎等化石的海相碳酸盐岩地层。该地层的岩石组合特征及生物群面貌与区内已知的地层存在明显的差异，其地质时代也明显早于区内已知的其它古生代地层，故建立下奥陶统拉塞组。     

海南岛含杜内早期腕足动物群层的发现

白沙县金波附近的 Spirifer subgrandis Rotai,Unispirifer extensus Tan,Fusella tornacensis (Koninck) ,Punctospirifer insculptus (Phillips) ,Marginatia huaqiaoensis Tan,Palaeochoristites sp.,Megachonetes sp.,Plicochonetes sp.,Schuchertella sp.,Pustula sp.,Sentisia sp.,Crurithyris sp.,Rhipidomella spp.等是海南岛首次发现的最丰富的杜内早期腕足动物群。据此 ,该地区含化石的南好组第四段确定为下石炭统岩关阶 ,似可与湖南马栏边组、黔南汤耙沟组等层位对比。以石燕贝类最繁盛、长身贝类数量少为特征的该动物群与华南其他地区同期腕足动物群存在诸多相同属种但又有明显差异。     

福建安溪尾厝和长泰钟魏二叠系上统大隆组的确定及认识

笔者在1:20万龙岩幅的尾厝,钟魏原划为(T_1x)、(T_3w)的一套浅灰土黄、浅紫色薄层状泥岩,粉砂岩,细砂岩中采有:Haydenella SP.,Orthoteina SP.,Waagenites SP.,Spinomarginifera SP.,Oldhamina sp.,Leptodus sp.,Neowellerella sp., Uncinuellina sp.,Crurithyris sp.,Edriosteges sp.,等化石;并测制了剖面,通过剖面发现其上与溪口组为整合接触;其下与翠屏山组也为整合接触,并在(P_2cp)粉砂质泥岩中采有其常见的植物化石如下:Neuropteridium Coreainicum, Gigantopteris sp., Compsopteris sp.,Fascipteris densata, Labatannularia sp., L.multifolia等化石。上述化石经省区测队王国平工程师鉴定;认为其生物群为晓二叠世大隆组的常见分子。笔者结合其岩性岩相、生物群组合、地层的上下接触关系及与邻区的龙岩雁石、华安草坂等地的大隆组进行比较,认为其层序相当,可以进行对比。故将上述二地所出露的地层划归为晚二叠世大隆组。对于上述二地地层时代的确定及划分,它对今后进一步恢复晚二叠世时的岩相古地理、沉积环境能有一定帮助。由此联想到福鼎南溪中下石炭统的存在事实,因此表明在政和——大埔大断裂以东及南部,在大面积中生代又山岩盖层之下,可能还有上二叠大隆组的存在,工作中应给予注意。     

内蒙古新巴尔虎左旗罕达盖地区早泥盆世化石的发现及其意义

2007年在内蒙古自治区呼伦贝尔市新巴尔虎左旗罕达盖地区开展1/5万矿产调查时,在原划分为中奥陶统多宝山组的灰岩中首次发现早泥盆世化石:牙形刺Pseudooneotodus beckmanni,Belodella resima,Belodella devonica,?Caudicriodus sp.;竹节石Nowakia sp.,?Homoctenus sp.;介形虫Tricornina sp.,Praepilatina sp.,Tetrasaculus sp.,Microcheilinella sp.,从而将这套缺少时代依据的地层确定为早泥盆世,归为泥鳅河组。     

华北板块北缘东段上三叠统的若干特征

位于华北板块与古蒙古洋板块的交接处、金银别河至白水滩一带的一套变质的陆相碎屑岩,前人命名为白水滩组,时代归属早侏罗世。80年代末笔者在此进行1∶5万区域地质调查,在该地层中采到了Neoclamites sp.,Cycadocarpiclium sp.,Uniohuang bogouensis(?)等重要分子,同时发现其被二长花岗岩(U—Pb 192.7Ma)侵入,暂与小营子组对比,将其时代归属为晚三叠世。该套地层分为上下两段,即下部砾岩段和上部砂岩段;地层褶皱形态复杂,断裂构造发育,新老地质体相互推覆掩盖,构成独特的地质景观。
