Assuming the flat and delta files could be recovered and are healthy, it should be possible to re-create the snapshot chain. However, depending on how many snapshots there are and whether you were also able to recover the latest vmware.log files this can be tricky.
To start with, create a file listing (ls -lisa > filelist.txt), then download this filelist.txt file from the datastore along with the existing vmware*.log files, the current .vmdk header files, the .vmsd file as well as the .vmx file, compress/zip the files and attach the .zip file to a reply post (you have to switch to the Advanced Editor to be able to attach files).
To minimize risks, you may - unless already done - backup the current files now!
