The geochemistry and submarine exhalitive genesis of sulfide black shalein Xinglong district, Hebei

A thickness varying, sulfide containing, black laininar shale occurs at the footwalls of the massive sulfide deposits in Xinglong Kuancheng district, Hebei. The shale contains 4.04% Zn and 11.73% S in average. Sphalerite and pyrite occur, separately, within the shale in the form of lamina. A series of characteristics of the shale of lamina type, mineralogy, principal chemical composition, microelements, REE and Si O isotope composition can refer it to a hot water sedimentary rock different strongly from a common marine black shale. The sulfide carrying this kind of black shale represents a product of submarine exhalation in a rift basin and has a special genetic tie with massive sulfide deposits, thus probably serving as understanding sulfide deposit origination and guiding deposit prospection.
