CENOZOIC GEOLOGY OF THE WENHO-SSUSHUI DISTRICT OF CENTRAL SHANTUNG

1. Syclinal warping at the end of the Cretaceous time?(Phase Ⅲof Yenshan Movement?).Intermont sedimentation.Deposition of the lowerand middle portions of the Kuanchuang Series during the Eocene(and earlyOligocene?)time. 2. Block-faulting and progressive tilting during the late Oligocenetime(Nanling Movement).Accumulation of the "bajada breccias" in con-nection with the faulting and the inauguration of the Tanghsien consequentdrainage system. 3. Tanghsien erosion to full maturity during the Miocene time. 4. Prolonged period of chemical weathering.Fossil soils withmanganese-iron pisolites and karst surfaces formed(Pliocene). 5. Deposition of gravels(Late Pliocene?). 6. "Z erosion" of moderate dissection followed by the accumula-tion of the Concretionary Reddish Loams (Lower Pleis cene). 7. Chingshui dissection along old lines,followed by the deposition ofbrownish-gray loams and loess of the Malan epoch(Upper Pleistocene). 8. Present cycle of erosion and deposition.     

新採集之脊椎動物化石簡報

一年以來,關於新生代骨化石之採集與研究,續有進展。除賈蘭坡在四川,技工王存義在河北邢台西所獲標本爲前所採集,新經研究者外;關於第三紀初期者,李悅言在河南盧氏,卞美年在雲南曲靖及魯南,均獲有確切無疑之始新統或漸新統     

新生代地質研究与經濟地質

在地質研究中,新生代地質,向來是最易被人忽略的一部分,早年的地质報告中,提到第三纪第四纪地層,每以数十字成十餘字了之,最普遍的無非是紅色岩系或第三紀初期砂岩,三趾馬紅土或黄土等而已。一般的地质调查,多注意新生代以前地層,故此等现象,本無足怪。     

中國之鴕鳥蛋化石

(一)過去研究中國北方各地新生代後期各地層中,常有易見的一種化石,就是鸵鳥蛋。他的骨格雖也有發見,但至今所知尚少。獨其蛋皮,差不多每次旅行,都可以採得若干,但完全的究爲少數。安特生在他的中國北部之新生界一書中,有一篇文章,專門討論鴕鳥     

非常時期之地質界

现在中國遭遇空前的國難,一切工作,均不能照预定計劃,按步就班的進行,乃是意料中事,我們地質界,當然也不能成爲例外。有許多人,值此緊張關頭,把握不住個人的意志,往往陷於過分的悲觀,情緒很緊張,乃至日常最低限度應作之事,亦不能好好的辦。我以為這是最不應該的。現在就鄙見所     

A MIOCENE FOSSIL FROG FROM SHANTUNG.

Among a large collection of plants,insects,fishes,turtles andmammals recently collected by the author near Lingchühsien,Shantung,a well preserved fossil frog and numerous impressions of tadpoles are     

THE CENOZOIC SEQUENCE IN THE YANGTZE VALLEY

On the whole the sequence of the Cenozoic formations in the Yangtzebasin and its provisional correlation with the Cenozoic sequence in North China,can be expressed in the following table: ON THE POSSIBILITY OF PREHISTORIC FINDS IN THE YANGTZE VALLEY (1) Generally speaking,possibilities of discovering traces of PalaeolithicMan in the Yangtze basin are rather limited,either on account of the poordevelopment of the Late Pleistocene beds,or on account of their unpromisingfacies(silt or mud). Nevertheless,methodical researches should be started in the extensivepits opened for brick industry in the lower terraces of the Yangtze,for instance,near Nanking in the Hsiasu Loam.Fig.12.An artifact collected on the ground west of Wanshien.Natural size. (2) An attractive field for the search of stony implements would bethe superficial deposits capping the 30-meter terrace developed so extensivelyalong the Yangtze.The Yuhuatai gravels,composing this terrace,contain alarge amount of siliceous pebbles remarkably fitted for the development of astony industry. (3) West of lchang,there is still a better material for stony implementsrepresented by the large pebbles of hard quartzite forming the gold-bearing gravel of the Yangtze.Most probably,if the Red Basin of Szechuan wascovered by loess,palaeolithic flakes would be common in its basal gravel.Un-fortunately,the Mesozoic ground is exposed almost everywhere,in a barrenand cultivated condition,this fact rendering researches difficult,and eventually,interpretation of finds rather difficult.Our figure 12 illustrates a retouchedflake of siliceous pebble collected along the Yangtze,some 10 kilometers westof Wanhsien(nght bank of the river).The specimen was picked up from theground,at a point a little higher than the loamy terrace 1 represented in ourfigure 11.The piece is distinctly incrusted,and differs by its shape from theNeolithic implements(mostly polished celts)commonly observed along theYangtze banks.But its pre-Neolithic age is impossible to prove. (4) As the most promising field for Palaeoanthropology still remainthe fossiliferous dissolution pits spread over the karstic plateaus of the Wanhsienarea.As observed by Granger,those pits have most been worked as naturaltraps,and never represented a dwelling place for animals.Yet the possibilityof discovering somewhere(as in Kwangsi,cf.Teilhard,...Chang,1935)anhabitated cave is not excluded. (5) A special re-investigation is necessary of the Tatsienlu area inwhich quartzite flakes associated with pot sherds have been collected in a kindof loess by Edgar and Bowles.Our own suspicion is that the Tatsionlu loessreally is Late Pleistocene,and the fragments of pottery secondary additions inthe deposits.     

NOTE ON A MAMMALIAN MICROFAUNA FROM YENCHINGKOU NEAR WANHSlEN,SZECHUAN

While on a trip to Szechuan in the spring of 1934,I spent a few days,together with Dr.G.B.Barbour and P.Teilhard de Chardin,at Wanhsien,inorder to visit the famous fossiliferous site of Yenchingkou.The latter site hadalready been visited and excavated in 1921-23 and 1925-26 by Dr.WalterGranger of the Third Asiatic Expedition of the American Museum of NaturalHistory~1.     

ON THE FISSURE DEPOSITS OF CHINGHSINGHSIEN(井陘县) WITH REMARKS ON THE CENOZOIC GEOLOGY OF THE SAME AREA

In August 1933, the writers of the present paper were sent by the Geological Survey to Chinghsinghsien along the Chengtai Railway, on the Hopei and Shansi border, to examine the long known but not sufficiently surveyed     

ON SOME NEOLITHIC (AND POSSIBLY PALAEOLITHIC) FINDS IN MONGOLIA,SINKIANG AND WEST CHINA

In the course of the past two years,when they were in the field with theThird American (1930) and the Haardt-Citroen (1931) Central Asiatic Expedi-tions,the authors of the present note had opportunities for making a series ofarchaeological observations over an extensive area.It seems interesting to report
