<正>This study aims to uses paleomagnetic and anisotropy of magnetic susceptibility(AMS)methods to recognize the initial deposit position and to track the paleoflow at the origin of an iron skarn-related deposit.The Yamansu deposit is located in eastern Tianshan(Charvet,2007).This province has a substantial mining potential for Fe–(Cu)skarn,Cu–Ni and V–Ti orthomagmatic deposits,and orogenic Au lodes(Branquet et al.,2012;Zhang et a.,2005;Mao et al.,2005).Recent publication dates the Yamansu deposit at 323 Ma,and uses this deposit to define a model of Submarine Volcanogenic Iron Oxide(SVIO)deposits(Hou et al.,
