EXPLANATION OF PLATES XV & XVI. 

 [All the figures are magnified 20 diameters.] 



Plate XV. 



Fig. 1. Tourmaline-rock: Parapara. The marked cross-fracture is shown 

 in the coarse tourmaline-crystals. (See p. 354.) 



2. Dunite: Dun Mountain, Nelson. The slide shows rounded grains 



of olivine, with some chromite (black). (See p. 357.) 



3. Garnet-pyroxene rock or garnet-gabbro : from the contact- 



zone, Nelson. The darker portion is lime garnet (grossularite) ; the 

 lighter parts consist of diallage. (See p. 358.) 



4. Epidote-rock : from the contact-zone, Nelson. The slide shows a 



mass of interlacing crystals and needles of epidote. The black 

 fragments in the centre are of pyrrhotite. (See p. 358.) 



5. Amphibole-serpentine rock: from the contact-zone, Nelson. 



Consists of veinlets of fibrous amphibole (grey) ramifying through 

 serpentine (colourless). (See p. 359.) 



6. Serpentinized dunite: Nelson. Residual cores of olivine in a 



mesh of serpentine, with a few grains of chromite. (See p. 357.) 



Plate XVI. 



Fig. 1. Bowenite: Anita Bay (Milford Sound). A very fine-grained, foliated 

 serpentine aggregate. Polarized light. (See pp. 361-62.) 



2. Bowenite matrix: Anita Bay (Milford Sound). Plates of talc 



appear in the centre. The remainder of the slide shows colourless 

 foliated serpentine (bowenite), with a few small grains of chromite 

 and some intermixed magnesite. (See p. 362.) 



3. Bowenite matrix: Anita Bay (Milford Sound). The slide shows 



flakes of coarse foliated talc, partly altered to bowenite. (See p. 363.) 



4. Nephrite: Griffin Range (Westland). The slide shows the typically 



foliated structure of the dense amphibole aggregate. Polarized light. 

 (See p. 373.)
