摘要
浙东南萤石型金矿赋存于萤石矿田中，是一个受陈蔡群层位控制的新类型金矿。矿石中金最高含量为５４×１０－６，一般５×１０－６～２５×１０－６，主要工业矿物为银金矿。原始矿液中，金和氟、硫关系密切，早期金以［ＡｕＦ４］－、［ＡｕＦ２］－形式运移；中期以［ＡｕＳ２］－、［ＡｕＳ３］３－、［ＡｕＳ］－、［Ａｕ（ＨＳ）］０等形式运移。成矿有多期次的特征。矿石中还含Ｓｅ。
Fluorite gold deposit,a new type of gold deposits,is hosted in the fluorite orefield and controlled by Chencai group horizon.The deposit locates Southeast of Zhejiang.The highest Au content in the ore is 54×10 -6 ,the general is 5×10 -6 ～25×10 -6 ,the main industrial mineral is electrum.Au has a close relation with F and S in the original ore fluid. Au is migrated in the forms of -、 -in the early stage,in the forms of [AuS 2] - 、[AuS 3] 3- 、 - 、 0,etc.in the medium stage.There is a characristic of multiperiodic ore forming.Ores are still Se bearing.
