Every journal seems to have a philosophy on what constitutes an appropriate research paper.
Textural characteristics of siliciclastics, micropaleontology, carbonate mineralogy, and petrographic studies of all types filled each issue. The proportion has shifted gradually to larger B issues over the 5 year period since the division. It is clearly an international journal. Thus, papers must be written with that in mind. Parochial research results that are only applicable to geologists working in the immediate geological area are not appropriate.
