It depends on what application do you want to use the Lu-Hf method.

There are several papers discussing the use of the Lu-Hf method for a number of applications.

For application on detrital zircon grains for provenance analysis you can look for a paper of Bertotti et al. 2014

For application on granite and crustal evolution you can take a look a paper of Linnemann et al. 2014:

http://dx.doi.org/10.1016/j.precamres.2013.08.007

You should always take a good look on the books dealing with isotope geology, such as the Faure's book.

Hope this will help.

Springer just published an Encyclopedia of Scientific Dating Methods, covering all major techniques for the Earth Sciences. There is a search option and you possibly find all sorts of applications/limitations for Lu-Hf

Thanks Felipe Guadagnin and Oliver Nebel for your valuable answers on my interest. Basically I am dealing with sedimentary rocks from Foreland basin of Nepal Himalaya. I will go through the suggested papers from you and hope to be in touch with you all in near future too....
