Gonzha terrane is located in the southern part of Mongolo-Okhotsk fold belt, within the northern part of Argun terrane. A large number of superlarge-large gold deposits lie in Gonzha terrane, such as Pionernoe, Burinda, Pokrovskoe and Borgulikan. These deposits are closely related to the intrusions and subaerial volcanic accumulations. Petrogeochemical studies indicate that the granodiorite-diorite assemblage is enriched in LILE (such as K, Rb, Ba), mobile incompatible elements (such as U, Th, Pb) and light rare earth elements (LREE), relatively depleted in HFSE (such as Ta, Nb, P, Sr, Ti) and heavy rare earth elements (HREE). The chondrite-normalized REE patterns display pronounced LREE enrichment and HREE depletion, slightly negative or no Eu anoma?lies (δEu=0.78~0.93, averagely 0.86), and no Ce anomalies (δCe=0.89~0.97). Geochemical characteristics of elements imply that the granodiorite-diorite assemblage was formed in an island-arc environment on continental margin, with characteristics of obvious crust-mantle mixing. LA-ICP-MS zircon U-Pb studies indicate that ore-bearing diorite porphyry in the Pionernoe Au-Ag depos?it has a weighted mean 206Pb/238U age of 113.8 ± 2.0Ma, whereas ore-bearing monzodioritic porphyrite in the Borgulikan Au-Cu-Mo deposit has a weighted mean 206Pb/238U age of 112.7 ± 2.8Ma. The LA-ICP-MS zircon U-Pb ages for granodiorites related to metallogenesis in Pionernoe and Borgulikan are 117.2 ± 1.3Ma and 117.0 ± 3.6Ma, suggesting that the Pionernoe Au-Ag deposit and the Borgulikan Au-Cu-Mo deposit were formed in Early Yanshanian period, and their formation ages are consistent with formation ages of Sandaowanzi and Doan gold deposits in Heilongjiang Province.

Qiupigou deposit is located in the Lesser Xing'an range-Zhangguangcai range metallogenic belt.The systemic field geological survey,zircon LA-ICP-MS U-Pb dating,test of major and trace element results show that the major elements(Ca,Ti,Al,Si,etc) are transferring among marble,skarn and limestone rocks,and the content of the elements among these rocks exhibits a linear change.The mineralization granites belong to ultraluminum and calc-alkaline rocks(A/CNK=1.26,Na2O/K2O=0.93,σ=1.27).The granites is enriched in Rb,Th,U,Nd,Yb,and depletion in Sr,P,Ti,which is compatible with the geo-chemical characteristics of subduction magma.The distributing pattern of rare elements are rich in LREE and deficient in HREE with negative Eu abnormalities.The same REE distributing patterns show that the granites have some relation in petrogenesis.The zircon U-Pb ages of 184.1±2.2 Ma show the granites formed in Early Jurassic.The Qiupigou deposit was formed later than 184.1±2.2 Ma and probably related to subduction of the Paleo-Pacific.

Balifang gold deposit,located in the northwest part of Heilongjiang Province,is one of the recently discovered gold deposits.The ore bodies are hosted in the diorite and arkose of the Middle Jurassic Emuerhe Formation.The ore types include gold and pyrite-bearing arkoses and quartz veins. Studies of petrogeochemistry indicate that the diorite,is with medium to low ∑ REE concentrations, enriched in LILE (such as K,Rb,Ba)and more mobile incompatible elements (such as U,Th,Pb), relatively depleting in HFSE (such as Ta,Nb,P,Sr,Ti).The chondrite-normalized REE patterns of the diorite samples display pronounced LREE enrichment and HREE depletion,slightly negative Eu anomalies (average 0.82),and no Ce anomalies (δCe=0.97~1.07).Geochemical characters imply that the Balifang diorite intrusion has the similar geologic characteristic to the island-arc and active continental margin magma.The arkoses has a wide range of ∑REE concentrations,slightly negative Eu anomalies (average 0.76),and no Ce anomalies (δCe = 0.91 ~ 0.99).The arkoses belongs to the sandstone series in active margin.Fluid inclusions in quartz veins can be classified into aqueous two-phase,CO2-bearing three-phase and pure CO2 types.The homogenization temperatures of aqueous two-phase and CO2-bearing three-phase inclusions range from 107.9 to 247.4 ℃,269.8 to 332.7 ℃,and the salinities(w(NaCl))range from 3.05% to 8.55%,4.41 to 10.29%.The ore-forming fluids are the hydrothermal system with medium-low temperature and low salinity.Combined with the geological characteristics of ore deposit,petrogeochemistry and ore-forming fluids,it can be concluded that the Balifang gold deposit belongs to the orogenic gold deposit.

The Sujia iron polymetallic deposit is located in the Zhangguangcai Range metallogenic belt of Heilongjiang Province,controlled by the Yizuomao alkali feldspar granite and granite porphyry.The orebodies were hosted in the contact zone of granite-porphyry and marble,and in the interlayer fracture zone,being mainly as skarn Fe-Zn orebodies in type.The metallic minerals of orebodies are composed mainly of magnetite and sphalerite.The alteration of wall rocks mainly were skarnized,petrified,hornfels,carbonation and chloritization in type,in which the skarnized was closely related to mineralization,being as the main prospecting criteria.The characteristics of geochemistry indicate that the metallogenic material mainly came from the evolution of crust-source magma and upper carbonate rocks.The hydrothermal mineralized bodies and orebodies occurred in the skarn rock which formed by the hydrothermal metasomatism with carbonate layer.Combined with the regional geological background,we determined that the Sujia iron polymetallic deposit was skarn deposit in type.

Ershisangongli gold deposit is located at the junction of Taipingling domes and Laoheishan fault basin.The deposit is a newly found hard rock gold deposit,which is still under exploration.9 orebodies are delineated in the mining area all of which occur as NE-trending and are controlled by NE-trending faults.This paper summed up the geological characteristics of Ershisangongli gold deposit,and on the basis of geological characteristics,a magma-related epithermal mineralization type deposit is concluded as the origin of the deposit.
