Research On Metallogenic Regularity And Metallogenic Prediction Of Gold Deposits Of Jinchang Dongning Town, Heilongjiang Province

The Jinchang gold deposit, located geographically in eastern Heilongjiang Province and tectonically at the easternmost portion of the Central-Asian Orogenic Belt, is one of the important gold districts in eastern Jilin-Heilongjiang provinces. this deposit has reserves of 100t of Au. Lots of work have been done since 50s last century including geosciences,geophysical prospecting,geochemical exploration,Remote Sensing, and finally get an common view that the deposit consist by four types of deposit. But until now the four type of deposits are studied isolately, but there are lots of evidence which can demonstrate that all type of deposites may create in the same system.Comparing the typical feature among the four types of deposit, the background of the deposit, the elements of forming a deposit, the process of deposit forming, and the final result of the deposit are studied within one system. Through studying the process and the rule of distribution of these deposits, finally we can built a deposit system with the concept of material field, energy field and spatial field. And with the system which we founded we can analyze the geochemistry date of the out area of jinchang deposit. After analyze the relativity of the elements we can fund the element which are most close with Au during the process of deposit forming. Using specify formal we can get the map of material field distribution and energy field distribution. Considering the condition of geology, finally we can get the minerogenetic prognostic map.
