Petrogenesis and metallogenesis of the Yaxi gabbroic intrusion associated with Fe-Ti-V-P ores in eastern Tianshan, NW China

An Fe-Ti-V-P ore deposit hosted by the Yaxi layered gabbroic intrusion was recently discovered in eastern Tianshan of the Central Asian Orogenic Belt (CAOB). The Yaxi intrusion is composed of interlayered leucogabbro and melagabbro, and the Fe-Ti-V-P ore layers are mainly hosted at the bottom of the melagabbro layers. We have studied the geology, petrology, mineralogy and geochemistry of the Yaxi gabbroic rocks and associated ore. Igneous...
