The Huanggangliang Fe–Sn deposit is located in the eastern section of the Central Asian Orogenic Belt (CAOB) and in the southern segment of the Great Hinggan Range polymetallic belt.
This deposit is the largest tin-based polymetallic ore deposit in the northern part of the North China plate.
The Fe–Sn mineralization principally occurs in skarn zones, which formed in the contact areas between granite intrusions and marbles.
Twenty-one δ values for sulfides from the Huanggangliang Fe–Sn deposit range from − 2.3 to 2.7‰, with an average of 0.38‰, and these values are interpreted to reflect a deep magmatic source of the sulfur contained within the ore minerals of the deposit.

The distribution of lead isotopic compositions from sulfides in the Huanggangliang Fe–Sn deposit exhibits a generally concentrated field, indicating that those sulfides have homogeneous lead isotopes and may derive from the same metallic source.
The existence of such identical Pb isotopic compositions of sulfides and host granites suggests that granitic magmatism was probably largely responsible for the Huanggangliang mineralization.
Molybdenites separated from ore-bearing quartz-veins yielded a Re–Os isochron age of 226.5 ± 5.1 Ma.
These age data confirm that both intrusion and related skarn mineralization initiated at ~ 227 Ma.
