Palaeomagnetic results from some panchet clay beds, Karanpura coalfield. Northeastern India

Abstract

Reversely magnetized Panchet clay samples of Early Triassic or possibly Late Permian age, from the North Karanpura coalfield (Damodar Valley, NE. India) revealed, after thermal cleaning, the mean direction: D = llO.S”, I = +69” (k = 49, tugs = 6” , N = 13). The corresponding pole position is: 59.5”W 7.5”s (dp = 9”, dm = IO”). A probable remagnetization of some Indian Gondwana red beds, during Late Cretaceous to Early Tertiary times, by the Deccan Trap flood basalts is indicated.
