Palaeomagnetism of Deccan traps from the Killari borehole flows

Borehole drilling in Deccan Traps at the Killari village, Latur District, M aharashtra, revealed nine Deccan Trap flows with a thickness of 338 m resti ng over a Precambrian basement, A palaeomagnetic study of drill core sample s from these flows using laboratory AF and thermal demagnetization methods revealed downward pointing magnetic inclinations with a mean value of + 56. 3 degrees. This suggests that these flows were erupted during a reverse pol arity period of the geomagnetic field. The mean magnetic inclination of the se flows is equal to the reported inclination of the eastern and south-east ern part of the Deccan Traps, From this correlation it appears that most of the Deccan Traps in the region were poured out at the same time supporting the suggestion that the Deccan flood basalts were erupted in a very short period of time.
