Abstract
Abstract Most of the sulfide nickel deposits in China occur on the margins of platforms and their outer mobile belts. The ore‐ bearing basic‐ ultrabasic rock bodies were formed in the Proterozoic and Variscan. The types of metallogenic rock bodies include ultrabasic‐ basic complexes related to volcanism in eugeosynclines and ultrabasic rock bodies, ultrabasic‐basic complexes and basic rock bodies related to deep fractures. On the basis of ore‐forming processes and modes, nickel sulfide deposits of China may be divided into two major types: in‐ situ magmatic liquid unmixing deposits and deep‐ seated magmatic liquid unmixing injection deposits. The latter may by subdivided into four types: single injection deposits, multiple injection deposits, and pulsatory injection depositis, and late injection deposits which may inject into either comagmatic rocks or other kinds of country rocks.Two metallogenic models for nickel sulfide deposits are proposed in this paper.
