Abstract

CODE SYSTEMS OF RESULTS OF GEOCHEMICAL STUDIES ON DISPERSED BITUMENS, OILS AND GASES Summary The paper discusses the use of index cards marginally perforated. The cards are used for establishing an archive of geochemical analyses of dispersed bitumens, oils and gas. The method of coding data on perforated cards according to triangle and quadrangle system is given, and each system is discussed in detail.
