摘要:First of all I want to express to the Directors of the National Geological Survey my profound gratitude for the invitation to visit Peking and for the privilege of seeing the impressive results of the work carried on under their

摘要:Ⅰ. HISTORY OF THE DISCOVERY. Many years ago (1892) A. Pomel (17, 18) described under the name of Cervus pachygenys, parts of the skeleton, and chiefly lower jaws, belonging to a fossil Deer from Algeria, this form being related, according to him, to the

摘要:For centuries the tufa of Niangtzekuan has possessed a peculiar fascination. It is to be seen decorating rock-gardens and fish-ponds all over North China, and is sold in curio-markets for use in flower-bowls, and as ornaments.

摘要:In connection with a study recently made of the famous tufa from Niangtzckuan, Dr. Barbour asked me to determine by analysis the relative amounts of soluble and insoluble matter so as to find out what proportion of the deposit is due to direct precipitation of mineral matter in solution and what amount is clastic material incorporated in the growing deposit.

摘要:The species of corals here described comprise the following.1. Favosites forbesi E. & H. vat kweitungensis Grabau2. Omphyma glomerata Grabau.3. Omphyma cystiphylloides Grabau.4. Cystiphyllum omphymiforme Grabau.5. Cystiphyllnm sp.6. Amplexus of lojopingensis Grabau.With these corals occur numerous well-preserved specimens of Spirifer tingi Gr. and several other brachiopods of undescribed species. Also a species of Holopea, probably H. yilungensis Gr.Though not large, this fauna is distinctive and consists of typical Silurian forms.The Spirifer tingi beds were first recognized as a part of the Miaokao group in the Chütshing region of East Yunnan, where these beds overlie the Lower Silurian Mientien group disconformably, and have an exposed thickness of 165 metres. The fauna in the typical section at Yilung comprises the following species~1.ANTHOZOA.Cladopora kütsingensis GrabauBRACHIOPODACamarotoechia of tongkinensis Mans.Spirifer (Eospirifer) tingi Grabau.PELECYPODAPterinea mientienensis GrabauActinopteria mansuyi GrabauModiolopsis miaokaoensis GrabauModiolopsis sp.Leda yilungensis GrabauPraecardium distans GrabauGASTROPODAHormotoma kütsingensis GrabauH. kütsingensis var. major GrabauHolopea yilungensis Grabau OSTRACODALeperditia tingi GrabauLeperditia sp.Entomis? corduroides GrabauIn the East Yunnan region, the Spirifer tingi beds are overlain by the Spirifer bourgeoisi beds, and these by higher beds with Ceratiocaris, while still higher beds with fish remains succeed these. None of these higher beds however, have so far been found in Kweichow. The stratigraphy is given in the following note by V. K. Ting.

摘要:INTRODUCTION The material studied has been in the Paleontogical collection of Columbia University for several years. The label on the material reads as follows: "Brought up by marine dredge from depths varying from 10. ft. to 40. ft. in the mud at the mouth of the Rio Grande near La Boca about one mile from

摘要:Ⅰ. INTRODUCTION. The Peipiao coal field is situated about 90 li North of the Chaoyang city, eastern Jehol and is connected with Chin Hsien, a station on the Peking-Mukden railway by a branch line of about 170 li. The region is characterized by a moderately dissected mountain range which runs roughly in a N. E. —S. W. direction.

摘要:Ⅰ. INTRODUCTION. The microscopical study of coal either by thin section or by polished section has formed now a special branch of geological science which is called in Germany "Kohlenpetrog(?)aphie." This name is not at all a satisfactory one as, so far as I know, it has been followed neither in America nor in European
