Is there any example of a welded lithic breccia lithofacies?

31 March 2019 0 2K Report

In massive lapilli tuffs welding seen from incipient to intense degree. Heat, loading, rheology and chemistry conditions of a current weld the pyroclasts. Pumices will be collapsed and elongated, vitric shards will be lineated and/or folded or may even the deposit resembles a lava. What will happen to lithic pyroclasts if they encounter welding conditions? Is there any example of a welded cooling unit which bears a lithic breccia lithofacies ?
