摘要: Abstract Radiometric determinations of Th, U, and K in 6 eclogites from metamorphic environments, 13 eclogitic rocks volcanic environments are given. Good agreement is found between radiometrically flamephotometrically determined potassium contents. The most important conclusions made this study are: 1. (a) the Th U ratio comparable to tholeiitic basalts orogenic type; 2. (b) derived upper portion mantle; 3. (c) data indicate a more complex history formation examined as compared with those environments.
