新安含镍基性岩体的岩石学、岩石化学及地球化学初步研究

A PRELIMINARY STUDY ON PETROLOGY, PETROCHEMISTRY AND GEOCHIMISTRY OF THE XINAN Ni-BEARING BASIC INTRUSION

通过对新安含镍基性岩侵入体的岩石学、岩石化学与地球化学研究,认为它与赤柏松含镍基性岩体是同源、同期、产于不同部位的孪生岩体,一旦有暗色橄榄辉长苏长岩相大量出现,则具找矿远景。

The article describes the petrological, petrochemical and geochemical characteristics of the Xinan Ni-bearing basic intrusion in the Chibansong orefield occurring in the Archaean terrain in the platform area, Jilin province, further providing that the Xinan Ni-bearing intrusion and large Rockbody No·1 of the Chibansong Cu-Ni sulphide deposit formed by the injection of ore magma are twined.The following characteristics, such as geological background, controlling structures,diagenetic epoch,sources of materials, lithofacies and their interrelation, diagenesis and mineralization regularities, and metallogenic prospect etc.are also very similar.
