Radon over Kimberlite Pipes: Estimation of the Emanation Properties of Rocks (Lomonosov Diamond Deposit, NW Russia)

In this paper, using the example of Lomonosov diamond deposit, experimental studies rocks were carried out to assess main radiation and physical factors affecting formation radon field over kimberlite pipes Arkhangelsk diamondiferous province. For various types rocks, represented by vent kimberlites, tuffaceous-sedimentary crater enclosing overlying sediments, following studied: porosity, density, activity radium-226, in a free state, level production, emanation coefficient. The research results showed that greatest amount state is produced near-pipe space, Vendian V2 deposits characterized high values coefficient, radium activity, production porosity. This fact associated with structural geological features which was exposed impact magma on host rocks. lowest these parameters are characteristic kimberlites facies, limits body pipe. create prospects for development methods searching conditions
