Abstract:Summary The coefficient of the gamma-ray absorption mgr Cs 137 investigated in eclogites of the Bohemian Massif varies with fresh samples from0.2477 cm –1 to 0.2804 cm –1 . Symplectite is the main factor decreasing the value of mgr down to0.242 cm –1 . On the contrary, the coefficient mgr increases with the increasing content of clinopyroxene and especially of garnet. The linear dependence of the coefficient mgr on the density phiv may be expressed by the equation mgr=0.0682phiv+0.028.
