Khurram:
You are not going to be able to restore just that missing partition (or even just that whole table) from the logs or archive to the source server. Your best bet will be to restore to another host and recover the table or just the missing data from there. First a question: are your archives taken using ontape or onbar?
If onbar, then you just need to perform an export of the archive and logical log backups to the target host, then perform a point-in-time restore to before the 7:19 drop of the partition.
If ontape, it is both easier and harder. Just copy the latest archive and logical logs that followed it up until the last logical log back up file before 7:19 to the target host and perform a normal restore stopping after restoring that last logical log and bringing that server online.
Either way, once the restored server is online, you should be able to export the missing data and insert it back into the original table after recreating the missing partition.
There is one other options, but it is more involved. You could try using archecker to extract the table (or just the data from the dropped partition) from the archive. That can be restored to a new table in the same server, then you can copy the data to the original table from there or detach the dropped partition from the restored new table and attach it back to the original table.
