Procedure forming a correlation database of marine strata:An example from global Cretaceous Oceanic Red Beds
Zeng Hung Xuan, Xianghui Li, Chengshan Wang · Journal of Chengdu University of Technology · 2006
By accumulation of a large amount of data on marine stratigraphy,a database has been established in order to decrease much boring work by manual operation for stratigraphic correlation.The sedimentary and geochemical information should be included in the database besides that of bio stratigraphy and chronostratigraphy.A procedure to build a database by Hood's software is introduced from an example of global Cretaceous Oceanic Red Beds(CORB).It is suggested that the procession of the database is going to be executed as: new files of stratigraphic sections→taxonomic dictionary files→catalog files→running the software GraphCor-results of database and graphs of correlation+ sedimentary data + geochemistry data →composite database.Some discussions on the choice of standard correlation section,first and last occurrence of a taxonomic,update and linkage of data are made.
