断裂-流体充填律与储矿空间选优——以小秦岭金矿带为例

Faults-fluids filling rules and ore deposited space selection take Xiaoqinling Gold Deposit for example

断裂-流体充填律是在含金流体充填定律基础上,进一步深入研究,升华为3个充填规律:流体在舒缓波状断层(Fb)中充填顺序,由自由空间→屏蔽空间,为第一个充填规律;到1条Fb的中心波→近相似波,为第二个充填规律;再到1组Fb的主Fb→第n对或第n个侧翼Fb,为第三个充填规律。根据充填律研究出内生脉型矿床空间的选优方法,包括断裂带(群)或矿脉带(群)选优,1组、多组Fb(矿脉)选优;1条Fb(矿脉)的波形选优和同一波形中的波段选优及第二轮选优。选优法找矿比传统法省时、省工、省钱。以小秦岭金矿带为例选优出次级矿带、矿脉组、矿脉和中心波。

Based on further study, the faults-fluids filling rules of auriferous.fluids divided into three. The frist rule consists filling sequence of fluids in the flat undulate fault （Fb ） that is from free space to screen space; the second rule ： the second sequence is from center wave to nearly similar wave of a single Fb ; the third law ： the third sequence is from major. Fb to the nth or the nth side Fb of a Fb group. Based on the filling rule, the selection method for the filling space of endogenous vein type deposits was determined, including for fault zone（ groups） or vein zone （groups）, for a Fb（vein） group and many Fb（vein） groups,for wave selection in a single Fb （vein） ,for wave band selection in the same wave and for the seceond section. The select method for prospecting takes tess time, strength and money than traditional methods. Take Xiaoqinling gold deposit for an example , the sub-mine zone, vein group, vein and center wave are selected.
