Extract

The olivine-rich rocks have acquired a particular significance in petrogenetic discussions as a result of the growth ofthe realization of the difficulties involved in postulating the existence of anhydrous melts of corresponding composition.The belief that such rocks have originated through the local accumulation of olivine crystals, without significant remelting (Bowen, 2, p. 108; 3, pp. 133–174)1 has received added support from the experimental determination ofthe melting relationships of the olivines. The facts “seem susceptible of no other interpretation than that, when such masses become rich in olivine, they do so through the accumulation of crystals of that mineral, which remain as such and do not become a part of the liquid by remelting or re-solution” (4, pp. 394–5).
