First of all, determine to which segment (if any) the block belongs.

col owner format a15
col segment_name format a20
col partition_name format a20
select owner, segment_name, partition_name, segment_type
from dba_extents
where file_id = 7
  and 76376 between block_id and block_id+blocks-1
/

Regards
Michel
