  boreal realm
The new ammonoid taxa belong to the family Arpaditidae, which was not previously recorded from the eastern Boreal Realm.
      
In the Boreal realm, condontophorids went through three stages of evolution comprising probably four substages and four phases, whereas three stages with six substages and twelve phases are distinguished in the Tethyan realm.
      
Lastly, a long-distance transect is constructed between the Vocontian Basin, Swiss Jura, northern France, and southern England, the last two areas being part of the sub-boreal realm.
      
The main results of this work are that: (1) third-order depositional sequences, and also higher-frequency sequences, can be correlated from the Tethyan to the boreal realm; (2) the sequence-stratigraphic interpretation given by Hardenbol et al.
      
Exchanges with the Boreal Realm to the north were possible.

The brachiopods described in the paper contain 9 genera and 11 species. They are all new species and there are 2 new genera. These fossil brachio- pods were collected from Zhaohuajing formation in Tongxin County, Ningxia. The age of these fauna approximates middle Llandoverian. Striispirifer and Eospirifer, Nalivkinia, pentamerid constitute 86%, 6%, and 5% of the total amount respectively. Clearly, the fauna correspond to Boucot's Striispirifer community of the 3 Benthic assemblage. The diagnosis of the 2 new...

The brachiopods described in the paper contain 9 genera and 11 species. They are all new species and there are 2 new genera. These fossil brachio- pods were collected from Zhaohuajing formation in Tongxin County, Ningxia. The age of these fauna approximates middle Llandoverian. Striispirifer and Eospirifer, Nalivkinia, pentamerid constitute 86%, 6%, and 5% of the total amount respectively. Clearly, the fauna correspond to Boucot's Striispirifer community of the 3 Benthic assemblage. The diagnosis of the 2 new genera are given as follows: Disulcatella gen. nov. Type species: Disulcatella didyma gen. et sp. nov. Diagnosis: Subequally biconvex Shell, small and smooth, Virginiadid with sulcus in both pedicle and brachial. Ventral interior with spondilium supported by median septum. Interior of brachial valve with parallel brachial plates. Imbricatospira gen. nov. Type species: Imbricatospira decora gen. et sp. nov. Diagnosis: Subeqtlally biconvex shell of small size, with pedicle sulcus and brachial fold, costellae simplex Ventral interior withe dental plates, dorsal interior with hinge plates. Like Clintonella but with lamellose growth lines. Nalivkinia Bublichenko, 1928, emend. Type species: Atrypa gruenwaldtiaeformis Peetz, 1901 Diagnosis: Subequally, biconvex, biconvex, costate shells, fold and sulcus lacking or developing anteriorly. Dental plates present, hinge plates discrete, spiralia dorsomedially directed, jugum simple, situated posteriorly. Remarks: According to specimens in Ningxia, we sugest replenish developing anterior fold and sulcus previously believed lacking.

本文描述腕足动物属11种,全部是新种,均产于宁夏同心照花井剖面S_(1-2)照花井群下部灰岩段。根据属种分析,时代为兰多维中期,根据属群数量统计分析,属于典型的Striispirifer群落,生物区系为早志留世北方大区的中亚-祁连亚区。

The Devonian System of Zhusileng Haierhan area, Ejina Qi, Neimongol was divided into four formations by Zhang et al (1983) , Zhusileng Formation, Yikewusu Formation, Wotuoshan Formation and Xipingshan Formation, belonging to Emsian, Eifelian, Givetian and Frasnian respectively. In thispaper four Middle and Upper Devonian sections are studied, and are divided into four sedimentation cycles, each making up one formation.

The Devonian System of Zhusileng Haierhan area, Ejina Qi, Neimongol was divided into four formations by Zhang et al (1983) , Zhusileng Formation, Yikewusu Formation, Wotuoshan Formation and Xipingshan Formation, belonging to Emsian, Eifelian, Givetian and Frasnian respectively. In thispaper four Middle and Upper Devonian sections are studied, and are divided into four sedimentation cycles, each making up one formation. They are from below upwards, Yikewusu Formation, Wotuoshan Formation, Lower Xiping-shan Formation and Upper Xipingshan Formation. On the basis of rugose coral assemblages and other associated fossils, the upper part of Yikewusu Formation and the lower part of Lower Xipingshan Formation are considered to be Givetian, while the upper part of Lower Xipingshan Formation and Upper Xipingshan Formation to be Frasnian in age. Famenian is absent in the area.

前人(张研等,1983)曾将珠斯愣海尔罕地区的泥岔系分为4个组:珠斯楞组、依克乌苏组、卧驼山组和西屏山组,分别属于埃姆斯期、艾菲尔期、吉维特期和弗拉斯期。本文描述了该区中、上泥盆统4个剖面,将其划分为4个沉积旋网,每个旋回构成一组,自下而上依次为依克乌苏组、卧驼山组、下西屏山组和上西屏山组。根据四射珊瑚组合和其它共生化石,把依克乌苏组上部到下西屏山组下部归入吉维持期,下西屏山组上部相上西屏山组的时代为弗拉斯期,木区缺乏法门期的沉积。 关于珠斯楞海尔罕地区所在的北方槽区泥盆纪的生物地理区系特征尚无统一认识。作者根据四射珊瑚动物群的地方性分子含量,Otsuka相似性系数和构造古地理,将中同泥岔纪的珊瑚分为3个大区:北方大区、北特提斯大区和南特提斯大区。这种划分方案也非常适用于吉维特期和弗拉斯期。 吉维持期到弗拉斯期,巴丹吉林区和扬子区珊瑚群的关系最为密切,与北天山——准噶尔区和内蒙古——兴安区共同的属很少。因此,广大的北方槽区属于两个不同的生物大区,北方大区和北特提斯大区,二者的界线是居延海——林西地壳对接带。这种认识与王鸿祯(1981)所划分的中国大地构造单元一致。

Silurian rocks in East Asia are encountered in the Siberia, Kolyma, Tarim-Sino-Korea, South China and other plates, as well as in those mobile belts composed of two or more ancient continental margins among these plates. A basic hierarchy for subdividing stratigraphic realms is here pro-posed. The largest unit of stratigraphic realm may be designated as a domain. Different plates generally belong to different domains)stable and mobile areas within the same plate may be attributed to different provinces; various litho-and bio-facies belts may be assigned to the subordinate unit, subprovinces. In the light of this schedule, the subdivisions of the Silurian stratigraphic realm in East Asia are summarized as follows: 1.Kolyma province (I1)

亚洲东部包括西伯利亚,科累马,塔里木—中朝和华南等古板块,以及围绕或穿插其间的活动带.不同古板块基本上被归于不同大区,同一大区中的稳定和活动地带属不同的一级地层区,同一区中的不同岩相和生物相带为不同的二圾地层区.志留纪时期除冈瓦纳古陆之外,其他各板块都分布在赤道两侧的低、中纬度地带,而且以南半球为主.在各古板块内的志留纪古地理面貌上,本文着重剖析华南古板块.志留纪的生物地理区系划分,虽然基于不同门类有不同的认识,但亚洲东部范围内均属北方大区.本文用生态地层学、沉积学,古地理学等方法研究了华南早志留世海平面升降的规律变化.
