Converting from .dat to netcdf(.nc)

I have a .dat file https://www.dropbox.com/s/8dbjg0i6l7a4sb6/CRUST10-xyz-complete.dat?dl=0 that I need to convert to either .grd or .nc, so that I can visualize the data in GMT(Generic Mapping Tool). I tried to do this using cdo using following command: 

cdo -f nc import_binary  CRUST10-xyz-complete.dat CRUST10-xyz-complete.nc

but got following error:

Open Error:  Unknown keyword in description file
  --> The invalid description file record is: 
  --> 0.5,89.5,4.19,0,2,0.7,0,0.73,1.62,5.01,14.25,10.06,7.36,2.7,1.5,3.81,2,3.5,0,5,6.5,7.1,8.07,5.5865805168986,6.7596467391304,2.3888888888889
  The data file was not opened. 

cdo import_binary (Abort): Open failed!

Can anyone please guide?

First make .ctl file then apply:-

cdo -f nc import_binary  CRUST10-xyz-complete.ctl CRUST10-xyz-complete.nc

Here is the example link for to make .ctl file. http://cola.gmu.edu/grads/gadoc/descriptorfile.html

It will definitely work for you. Thanks!

Without the data itself, it is hard to see what went wrong. In any case, just look at the following message from cdo forum: https://code.mpimet.mpg.de/boards/1/topics/3631

which you could use as an example of how to convert ASCII data to netCDF using cdo's.
