Hi,

if you want to create a mixture of materials, the 'fraction' tag calls the

G4Material::AddMaterial

method, which

has the signature

  void AddMaterial(G4Material* material,			//the material
                   G4double   fraction);			//fractionOfMass

so, the answer is mass fraction.

You can also create a mixture of elements by using the 'composite' tag, and in that case the method that would be called will be:

G4Material::AddElement, with the signature:

  void AddElement(G4Element* element,				//the element
                  G4int      nAtoms);				//nb of atoms in
		    						// a molecule

(so no mass fraction, but number of atoms).

Cheers, Witek
