摘要：

The bedded felsic tuff exposed in Rutland Island, Andaman, consists of two facies: white massive tuff with ill-defined bedding contacts (facies-A) anddominantly green tuff exhibiting well-developed turbidite sequence with up-section change from a massive unit to plane laminated units to ripple drift lamination (facies-B).
