Because of detection limitation, the gold particles are not found independently in pyrite, scheelite, quartz, and other minerals. So it is believed that submicroscopic gold can be found in gold-bearing minerals as micro-inclusions or isomorphous atoms.

由于受检测手段所限，在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

Because of detection limit the gold particles are not found independently in pyrite scheelite quartz and other minerals. So it is believed that submicroscopic gold are occurred in gold-bearing minerals as micro-inclusions or isomorphous atoms.

受检测手段所限在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以我们倾向于寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。
