桦树沟（ 铁）铜矿床矿石及含矿岩系的稀土元素、微量元素、稳定同位素、流体包裹体以及同位素年代学等地球化学研究表明，铜矿床形成于近大陆边缘的海底裂谷环境，成矿物质主要来自元古代基性火山岩，硫、碳主要来自海水。火山—沉积岩系经深循环水—热系统的作用，成矿物质被浸出和搬运，并经海底喷溢作用沉淀于海盆洼地中形成含矿层，后期变质作用使成矿物质活化、转移和富集。矿床成因为喷气（流）沉积—变质改造型（ 铁）铜矿床
The geochemical studies of rare earth elements, trace elements, stable isotopes, fluid inclusions and isotopic chronology of the ore and ore-bearing rock series of the Huashugou copper (Cu) ore deposit show that the copper deposits formed in the submarine rift near the continental margin Environment, mineralization material mainly from the Proterozoic basic volcanic rocks, sulfur, carbon mainly from seawater. The volcanic-sedimentary rocks are leached and transported by the deep-cycle water-heat system and deposited in the depression of the sea basin by seafloor spill-out to form a ore-bearing layer. Later metamorphism activates, transforms and enriches the metallogenic material . The genesis of the deposit is jet (flow) sedimentary-metamorphic (iron) copper deposit
