Uranium and yttrium accumulation in the bone debris in carbonaceous rocks of the Kamchatsky Mys Peninsula
The carbonaceous rocks composing the beds in the Cretaceous carbonate-siliceous paleoceanic sediments of the Kamchatsky Mys Peninsula (Eastern Kamchatka) were studied using a scanning electron microscope. In the matrix, which consists of organic and siliceous matter, abundant bone debris and phospha...
