Deccan Traps ....

Deccan Traps ....

Alan Silverstein <ajs at> in “Deccan traps ....” at

>It seems that somewhere I read that the Deccan

>Apparently not so. Recent news:

>after the impact..."

Although the Deccan traps started erupting prior
to the Chicxulub asteroid impact, it has been
proposed that the Chicxulub asteroid impact
resulted in cataclysmic eruptions of the already
active, but relatively sluggish, Deccan trap fissure
eruptions. Go seee;
