摘要:

Fossil plant associations are best named by traditional phytosociological methods from genera or species prominent in a reference collection. The named association then has some stability during later palaeoecological interpretation and threedimensional mapping in sedimentary basins. Biostrati‐graphic zones are best established from successions of events in similar associations within a specified area. Such events may not have occurred in other types of association, nor have been contemporaneous in separate areas. These events are most effectively correlated when the likely environment and ecology of the associations are also considere

摘要:

Quantitative treatment of the geological sciences must remain limited; there continues to be need for a language of words. This is keenly felt in stratigraphy, where the practising geologist is dismayed by the effusions of the stratigraphical philosophers. The situation, in so far as it appears to remain in some ways obscure or troublesome, is briefly reviewed in terms of lithostratigraphy. biostratigraphy. and chronostratigraphy. A revised version of a controversial diagram is presented, in which the role of the boundary stratotype as anchor point is believed to be clarified. Finally a synthesis is attempted of relationships between the various stratigraphical procedures and the provision of dates in years through the parallel discipline of geochronometry.
