Geochronology of minerrlization and tectonic setting of Baishidong skaro-type iron deposit in Helony aree of Yanbian,Jilin Province,NE China

The Baishidong iron deposit is the only skarn-type iron deposit discovered in the study area.According to mineral assemblage and paragenesis,the mineralization can be divided into four metallogenic stages:early garnet-diopside skarn stage,late magnetite-tremolite-epidote skarn stage,early quartz-pyrite-chalcopyrite stage and late quartz-calcite-pyrite stage.Through LA-ICP-MS zircon U-Pb dating of diorite,which is closely related to mineralization,the results show that the weighted average age is 164.6±1.4 Ma,which limits the mineralization time of Baishidong iron deposit during or slightly later than Middle Jurassic.The diorite rocks are rich in sodium(Na_(2)O/K_(2)O=1.24-1.76),aluminium(Al_(2)O_(3)=17.41%-18.76%),LREE and large-ion lithophile elements(Ba,K and Sr),depleted in HREE and high-field-strength elements(Y,Nb,Ta,P and Ti),and show strongly fractionated patterns(LREE/HREE=6.58-9.93),no apparent Eu anomalies(δEu=0.91-1.13),which shows similar characteristics to island arc or active continental margin arc magma.The zirconεHf(t)values range from-22.6 to 5.9,and the age of the two-stage model(t_(DM2))is 836-2633 Ma.Above data combined with the geochemical characteristics,it is indicated that the magma was a mixture of multiple sources,composed of ancient materials and newly formed crust.During the process of evolution and ascending of magma,separation and crystallization occurred,and a large amount of continental crust material was mixed at the same time.Combined with regional tectonic evolution,the formation of this deposit may be related to the westward subduction of the Paleo-Pacific Plate to the Eurasian Plate.

Consumers’ Awareness of Genetically Modified Food and Their Willingness to Buy in Yanbian Prefecture

Having a clear understanding of consumers' awareness of genetically modified food and their willingness to buy, plays a very important role in formulating the regulatory policy of genetically modified food and regulating the market of genetically modified food. This paper takes the supermarket consumers as the study object. Through on-site questionnaire survey, we find that consumers' awareness of genetically modified food is not high in Yanbian Prefecture, and their willingness to buy is also low; the prices of genetically modified food, consumers' income, educational level and so on, are the main factors that affect the willingness to buy. Based on this, we put forth the relevant recommendations: increasing publicity efforts to safeguard consumers' right to know and choose; increasing supervision efforts to improve the existing regulatory system of genetically modified food; actively organizing forces to carry out the study on safety of genetically modified food.

Re-Os isotopic dating and geological significance of molybdenite from Xintian Cu-Mo polymetallic deposit in Yanbian,Jilin

Xintian polymetallic deposit is a hydrothermal vein type Cu-Mo deposit. Analysis on Re-Os isotopic dating for the molybdenite from this deposit is undertaken to determine metallogenic epoch and dynamics setting of the deposit. Re-Os isotopic dating for the molybdenite yields model ages ranging from 123. 9 ± 1. 9 Ma to 124. 7 ± 1. 8 Ma,with a weighted mean age of 123. 4 ± 0. 81 Ma,and an isochron age of 127 ± 16 Ma,MSWD= 0. 25,indicating that the metallization was at late Yanshanian. The content of Re in molybdenite is( 330. 1± 4. 0--367. 9 ± 3. 1) × 10^(-6),which demonstrates mantle derived metallogenic sources. Integrating the regional tectonic evolution and the metallogenic characteristics of other contemporaneous Cu-Mo deposits in the region,it is suggested that the Cu-Mo mineralization of this deposit occurred in an active epicontinental environment under lithospheric extension resulted from the subduction of the Izanagi plate to the Paleo-Asia continental margin at late Yanshanian. The Mantle wedge was partially melted with large amount of metallogenic elements dissolved in it. Under the favorable conditions of crust-mantle interaction,large-scale magmatic activity turns out to be the important mechanism of the mineralization of many Cu-Mo deposits in the Xiaoxingan Range--Zhangguangcai Mountain metallogenic belt,including the Xintian Cu-Mo polymetallic deposit.

Ore-forming mechanism for the Xiaoxinancha Au-rich Cu deposit in Yanbian,Jilin Province,China:Evidence from noble gas isotope geochemistry of fluid inclusions in minerals

The Xiaoxinancha Au-rich copper deposit is one of important Au-Cu deposits along the continental margin in Eastern China. The deposit consists of two sections: the Beishan mine (North), composed of altered rocks with veinlet-dissemination sulfides and melnicovite-dominated sulfide-quartz veins, and the Nanshan mine (South), composed of pyrrhotite-dominated sulfide-quartz veins and pure sulfide veins. The isotope compositions of noble gases extracted from fluid inclusions in ore minerals, i.e. ratios of 3He/4He, 20Ne/22Ne and40Ar/36Ar are in the ranges of 4.45―0.08 Ra, 10.2―8.8 and 306―430, respectively. Fluid inclusions in minerals from the Nanshan mine have higher 3He/4He and 20Ne/22Ne ratios whereas those from the Beishan mine have lower 3He/4He ratios. The analysis of origin, and evolution of the ore fluids and its relations with the ore-forming stages and the ages of mineralization suggests that the initial hydrothermal fluids probably come from the melts generated by partial melting of oceanic crust with the participation of fluids from the mantle (mantle-plume type)/aesthenosphere. This also corresponds to the continental margin settings during the subduction of Izanagi ocaneic plate towards the palaeo-Asian continent (123―102 Ma). The veinlet-dissemination ore bodies of the Beishan mine were formed through replacement and crystallization of the mixed fluids generated by mixing of the ascending high-temperature boiling fluid with young crustal fluid whereas the melnicovite-dominated sulfide-quartz veins were formed subsequently by filling of the high-temperature ore fluid in fissures. Pyrrhotite-dominated sulfide-quartz veins in the Nanshan mine were formed by filling-deposition-crystallization of the moderate-temperature ore fluids and the pure sulfide veins were formed later by filling-deposition-crystallization of ore substance-rich fluids after boiling of the moderate-temperature ore fluids. The metallogenic dynamic processes can be summarized as: (1) formation of fluidand ore substance-bearing Adakitic magma by degassing, dewatering and partial melting during subduction of the Izanagi plate; (2) separation and formation of ore fluids from the Adakitic magma; and (3) success-sive ascending of the ore fluids and final formation of the Au-rich Cu deposit of veinlet-dissemination and vein types by secondary boiling.

From Teacher-Education University to Comprehensive University:Case Studies of East China Normal University,Southwest University and Yanbian University

Three different“logics”—that of the internal strategies of the institutions,the economic pressures of the socialist market economy and the political policies of the state drive the development of a university.The dynamic interaction and coexistence of the three logics has determined the transformation models of teacher-education or normal universities in China.This paper aims at describing and analyzing both the process and the forces that led to these transformations by taking East China Normal University(ECNU),Southwest University(SWU)and Yanbian University(YBU)as examples.Reliance on government and market resources has put these universities into a dilemma:On the one hand,they wanted to retain their original features so as to preserve their leading position in the“teacher education”market,and on the other,they needed to merge,expand,restructure and enhance their quality as they pursued overall development.The case analyses show that the teacher-education university’s need for self-development,which is the internal determinant,plays a critical role in its transformation.At the same time,the socioeconomic environment and national policies influence the institution while it displays considerable capacity for self-adjustment.
