THEORETICAL REFLECTICTIONS ON THE GEOMORPHOLOGY OF CHINA FROM THE VIEWPOINT OF GLACIO-EUSTATISM.

It is quite generally accepted that the growth of the Pleistocene ice-capsdemanded world-wide depression of mean sea-level; indeed,as Henri Bauligsays,"it expresses a physical necessity." There is striking evidence,moreover,for such a recent depression in the extension of river systems across the continental     

ON A MESOLITHIC(■)INDUSTRY OF THE CAVES OF KWANGSI

INTRODUCTION In the beginning of 1935,a party of geologists was sent by Di.W.H.Wong,Director of the Geological Survey,in order to survey the Cenozoicformations of Kwangsi.The party,including P.Teilhard de Chardin,Dr.C.C.Young and the author,was met in Canton and greatly assisted in thefield by Dr.H.C.Chang,Professor at the Sunyatsen University (Canton).

RELATIONSHIP BETWEEN P-T CONTITIONS OF TWO PHASES OF TAN-LU STRIKE-SLIP SHEAR ZONES AND DELAMINATION OF OROGENIC BELTS ON THE EASTERN MARGIN OF THE DABIE MOUNTAINS

The Tan-Lu fault zone joins the Dabie Mountains on its eastern margin, and offsets the Dabie and Sulu orogenic belts sinistrally for about 500 kin. On the basis of calculation of temperature and pressure experienced by the two phases of the fault zone as well as the thermo-chronological information on mylonite from the earlier and later Tan-Lu fault zones on the eastern margin of the Dabie Mountains, this paper discusses the delamination history and uplifting magnitudes of the Dabie Mountains from earlier Jurassic to earlier Cretaceous. From mineral assemblages, mineral deformation and muscovite-chlorite geothermometry calculation, it is known that the temperature experienced by the two phases of Tan-Lu fault zones are between 40℃ and 450℃, and the confining pressures are between 0.25Gpa and 0.36GPa for the earlier shear zones and 0.24-0.39GPa for the late shear zones. According to the geobarometry of Si-in-phengite and by considering shear heating and tectonic over-pressure, it is concluded that the maximum formation depths for the two phases of the ductile shear zones are not more than 12 kin. Differential formation depths for the two phases of shear zones are 1-2 km at most. At about 190 Ma and 128 Ma, the Tan-Lu fault zone experienced two phases of cooling events. During this period, the eastem margin of the Dabie Mountains experienced a tectonic calm period and no uplifting. According to information from the Tan-Lu fault zone, the uplifting magnitudes of the Dabie orogenic belts are not more than 12 km during the earlier Cretaceous.     

PHYSICAL ENRICHMENT--A NEW THEORY ON THE GENESIS OF INDUSTRIAL PHOSPHORITE DEPOSITS

Sedimentary mineral deposits were not formed simply as product of simplereactions through a single kind of factors,but were outputs of intricate reactionsamong a complex set of evolutionary natural environmental agents.They were formedat least through three different stages,viz.,the imbibition and concentration ofore forming materials;the geochemical enrichment;and the physical concentrationstages(Fig.1).As to industrial phosphorites,physical enrichmnt is of paramountimportance.It seems,almost all of the world industrial phosphorite deposits wereformed as such.Our idea of physical enrichment was first set up in 1980,during the 2ndNational Symposium on Mineral Deposits at Hongchow.Since then,lots of newevidences had been added up.In this paper,only those of phosphorite deposits are described.
