Distribution of gold resources in orogenic gold deposits and related placer gold endowment over geologic time. A. Precambrian gold resources are mainly the product of ore-forming events clustered between 2.8 and 2.55 and 2.1 and 1.8 Ga. B. Phanerooic gold resources indicate relatively continuous gold-forming events during orogenic events
AbstractBased on the sampling of ore bodies and surrounding rock systems at the surface and deep of the Hatu gold mine and the study of quart inclusions and oxygen isotopes it is believed that the Hatu gold mine is an orogenic type medium-low temperature mixed hydrothermal gold deposit.

The third phase ductile-brittle shearing process of Yanshanian period provided favorable ore-hosting conditions for the large-scale injection of ore-forming fluids and mineraliation. Researches show that the ore-forming fluids were mainly derived from the depth and through the multistage evolution of mantle plume injected into the ductile shear one to form ore deposits via accumulation
