摘    要:本文对砂金矿物的形态、表生显微结构及残留原生结构、化学成分及杂质元素、气液包体成分及爆裂温度进行了研究。认为该区的砂金以碎屑成因为主,化学成因仅占很次要的地位,砂金的原生来源为海西-燕山期的斑岩型和火山岩型金矿床。

关 键 词:砂金矿物 成因 金矿床

A DISCUSSION OF THE ORIGIN OF PLACER GOLD AS EXEMPLIFIED BY PLACER GOLD DEPOSITS IN THE HUNCHUN AREA, JILIN PROVINCE
Wu Shangquan Yang Yi Song Qun. A DISCUSSION OF THE ORIGIN OF PLACER GOLD AS EXEMPLIFIED BY PLACER GOLD DEPOSITS IN THE HUNCHUN AREA, JILIN PROVINCE[J]. Acta Mineralogica Sinica, 1992, 12(3): 261-266,T001

Abstract:This paper deals with the following problems: (1) the morphological characters of placer gold; (2) the hypergene and relict protogenic microtextures; (3) the chemical compositions and contents of impurity elements; (4) the compositions and forming temperatures of fluid inclusions; and (5) the Pb isotopic composition of placer gold. It is concluded that the placer gold, mainly clastogene and only a small amount was chemogenic, seems to have been derived from some Yenshanian and Hercynian porphyry and volcanic-type gold deposits.
Keywords:placer gold  clastogezne  chemogenic
