Title: Use of Mercury for Determination of Volume of Rock Specimens in Russell Porosity Apparatus

Author(s): W. B. Gealy (2)


A method is described wherein mercury is used in porosity determinations to measure the volume of the rock chunk. Inasmuch as mercury does not enter the pores of a consolidated rock, it is not necessary to dip the specimen in paraffin. The volume is measured in a Russell porosity apparatus, mercury, rather than acetylene tetrachloride, being used. The use of mercury saves time and eliminates the error of estimating the outer surface of the specimen. Comparisons with results obtained by dipping the specimen in paraffin and weighing in water show that the method is quite accurate.
