Experimental introduction of excess Ar40 into a granitic melt
Samples of a Precambrian granite were melted in sealed capsules to produce a radiogenic Ar 40 atmosphere over the melt. The amount of Ar 40 incorporated in the quenched charge was then determined. Under these experimental conditions the amount of argon dissolved in the quenched melt was appreciable and could be an important source of error in potassiumargon dating.
