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.  相似文献

川西磷酸岩   总被引:4,自引:0,他引:4       下载免费PDF全文
孙枢  陈其英  陈开会 《地质科学》1973,8(3):196-216
川西磷酸岩的特征,对阐明磷的沉积作用和磷块岩的成因,有一定的重要性。多年来,四川省地质局在该区作了大量的详细的勘查和研究。这里仅就我们的工作所及,讨论磷酸岩的一些沉积学问题。一、含磷岩系的岩性序列与岩相系列掌握含矿岩系本身在纵横两个方向上变化更替的规律,对沉积矿床的勘查是很重要的。这种变化规律,可以用岩性序列与岩相系列表示之。岩性序列是含矿岩系的各个岩类在纵剖面上转换的次序,反映它成生时期沉积盆地的地质、自然地理、物理、化学和生物等诸方面的状况及其在时间上的演化;而岩相系列则是含矿岩系的各个岩类及其组合在横向上的转换次序,反映上述诸方面状况在空间上的演变。  相似文献
